Our setup code wants to ensure that the haveged service is running, and furthermore at least the agent-subprocess test assumes that there's an init to reap zombie processes and doesn't work in (e.g.) autopkgtest-virt-unshare. * New upstream release (https://www.openssh.com/releasenotes.html#9.7p1): - ssh(1), sshd(8): add a "global" ChannelTimeout type that watches all open channels and will close all open channels if there is no traffic on any of them for the specified interval. This is in addition to the existing per-channel timeouts added recently. This supports situations like having both session and x11 forwarding channels open where one may be idle for an extended period but the other is actively used. The global timeout could close both channels when both have been idle for too long (closes: #165185). - All: make DSA key support compile-time optional, defaulting to on. - sshd(8): don't append an unnecessary space to the end of subsystem arguments (bz3667) - ssh(1): fix the multiplexing "channel proxy" mode, broken when keystroke timing obfuscation was added. (GHPR#463) - ssh(1), sshd(8): fix spurious configuration parsing errors when options that accept array arguments are overridden (bz3657). - ssh-agent(1): fix potential spin in signal handler (bz3670) - Many fixes to manual pages and other documentation. - Greatly improve interop testing against PuTTY. * Skip utimensat test on ZFS, since it seems to leave the atime set to 0. * Allow passing extra options to debian/tests/regress, for debugging. * Fix gssapi-keyex declaration, broken when rebasing onto 8.9p1 (LP: #2053146). -- Colin Watson Thu, 14 Mar 2024 10:47:58 +0000 openssh (1:9.6p1-5) unstable; urgency=medium * Restore systemd template unit for per-connection sshd instances, although without any corresponding .socket unit for now; this is mainly for use with the forthcoming systemd-ssh-generator (closes: #1061516).

This attack allows a MITM to effect a limited break of the integrity of the early encrypted SSH transport protocol by sending extra messages prior to the commencement of encryption, and deleting an equal number of consecutive messages immediately after encryption starts. A peer SSH client/server would not be able to detect that messages were deleted. - [CVE-2023-51384] ssh-agent(1): when adding PKCS#11-hosted private keys while specifying destination constraints, if the PKCS#11 token returned multiple keys then only the first key had the constraints applied. Use of regular private keys, FIDO tokens and unconstrained keys are unaffected. - [CVE-2023-51385] ssh(1): if an invalid user or hostname that contained shell metacharacters was passed to ssh(1), and a ProxyCommand, LocalCommand directive or "match exec" predicate referenced the user or hostname via %u, %h or similar expansion token, then an attacker who could supply arbitrary user/hostnames to ssh(1) could potentially perform command injection depending on what quoting was present in the user-supplied ssh_config(5) directive. OpenSSH 9.6 now bans most shell metacharacters from user and hostnames supplied via the command-line. - ssh(1), sshd(8): the RFC4254 connection/channels protocol provides a TCP-like window mechanism that limits the amount of data that can be sent without acceptance from the peer. In cases where this limit was exceeded by a non-conforming peer SSH implementation, ssh(1)/sshd(8) previously discarded the extra data. From OpenSSH 9.6, ssh(1)/sshd(8) will now terminate the connection if a peer exceeds the window limit by more than a small grace factor. This change should have no effect of SSH implementations that follow the specification. - ssh(1): add a %j token that expands to the configured ProxyJump hostname (or the empty string if this option is not being used) that can be used in a number of ssh_config(5) keywords. - ssh(1): add ChannelTimeout support to the client, mirroring the same option in the server and allowing ssh(1) to terminate quiescent channels. - ssh(1), sshd(8), ssh-add(1), ssh-keygen(1): add support for reading ED25519 private keys in PEM PKCS8 format. Previously only the OpenSSH private key format was supported. - ssh(1), sshd(8): introduce a protocol extension to allow renegotiation of acceptable signature algorithms for public key authentication after the server has learned the username being used for authentication. This allows varying sshd_config(5) PubkeyAcceptedAlgorithms in a "Match user" block. - ssh-add(1), ssh-agent(1): add an agent protocol extension to allow specifying certificates when loading PKCS#11 keys. This allows the use of certificates backed by PKCS#11 private keys in all OpenSSH tools that support ssh-agent(1). Previously only ssh(1) supported this use-case. - ssh(1): when deciding whether to enable the keystroke timing obfuscation, enable it only if a channel with a TTY is active. - ssh(1): switch mainloop from poll(3) to ppoll(3) and mask signals before checking flags set in signal handler. Avoids potential race condition between signaling ssh to exit and polling. - ssh(1): when connecting to a destination with both the AddressFamily and CanonicalizeHostname directives in use, the AddressFamily directive could be ignored. - sftp(1): correct handling of the limits@openssh.com option when the server returned an unexpected message. - ssh(1): release GSS OIDs only at end of authentication, avoiding unnecessary init/cleanup cycles. - ssh_config(5): mention "none" is a valid argument to IdentityFile in the manual. - scp(1): improved debugging for paths from the server rejected for not matching the client's glob(3) pattern in old SCP/RCP protocol mode. - ssh-agent(1): refuse signing operations on destination-constrained keys if a previous session-bind operation has failed. This may prevent a fail-open situation in future if a user uses a mismatched ssh(1) client and ssh-agent(1) where the client supports a key type that the agent does not support. * debian/run-tests: Supply absolute paths to tools. * debian/run-tests: Enable interop tests for Dropbear. -- Colin Watson Mon, 18 Dec 2023 22:35:25 +0000 openssh (1:9.5p1-2) unstable; urgency=medium * Upload to unstable. -- Colin Watson Sat, 25 Nov 2023 16:16:04 +0000 openssh (1:9.5p1-1) experimental; urgency=medium * New upstream release (https://www.openssh.com/releasenotes.html#9.5p1): - ssh-keygen(1): generate Ed25519 keys by default. Ed25519 public keys are very convenient due to their small size. Ed25519 keys are specified in RFC 8709 and OpenSSH has supported them since version 6.5 (January 2014). - sshd(8): the Subsystem directive now accurately preserves quoting of subsystem commands and arguments. This may change behaviour for exotic configurations, but the most common subsystem configuration (sftp-server) is unlikely to be affected. - ssh(1): add keystroke timing obfuscation to the client. This attempts to hide inter-keystroke timings by sending interactive traffic at fixed intervals (default: every 20ms) when there is only a small amount of data being sent. It also sends fake "chaff" keystrokes for a random interval after the last real keystroke. These are controlled by a new ssh_config ObscureKeystrokeTiming keyword. - ssh(1), sshd(8): Introduce a transport-level ping facility. This adds a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to implement a ping capability. These messages use numbers in the "local extensions" number space and are advertised using a "ping@openssh.com" ext-info message with a string version number of "0". - sshd(8): allow override of Subsystem directives in sshd Match blocks. - scp(1): fix scp in SFTP mode recursive upload and download of directories that contain symlinks to other directories. In scp mode, the links would be followed, but in SFTP mode they were not. - ssh-keygen(1): handle cr+lf (instead of just cr) line endings in sshsig signature files. - ssh(1): interactive mode for ControlPersist sessions if they originally requested a tty. - sshd(8): make PerSourceMaxStartups first-match-wins. - sshd(8): limit artificial login delay to a reasonable maximum (5s) and don't delay at all for the "none" authentication mechanism. - sshd(8): Log errors in kex_exchange_identification() with level verbose instead of error to reduce preauth log spam. All of those get logged with a more generic error message by sshpkt_fatal(). - sshd(8): correct math for ClientAliveInterval that caused the probes to be sent less frequently than configured. - ssh(1): fix regression in OpenSSH 9.4 (mux.c r1.99) that caused multiplexed sessions to ignore SIGINT under some circumstances. * Build-depend on dh-sequence-movetousr. * Report DebianBanner setting in "sshd -G/-T" output (thanks, Rasmus Villemoes; closes: #1053555). -- Colin Watson Thu, 23 Nov 2023 17:38:07 +0000 openssh (1:9.4p1-1) unstable; urgency=medium * New upstream release (https://www.openssh.com/releasenotes.html#9.4p1): - ssh-agent(1): PKCS#11 modules must now be specified by their full paths. Previously dlopen(3) could search for them in system library directories. - ssh(1): allow forwarding Unix Domain sockets via ssh -W. - ssh(1): add support for configuration tags to ssh(1). This adds a ssh_config(5) "Tag" directive and corresponding "Match tag" predicate that may be used to select blocks of configuration similar to the pf.conf(5) keywords of the same name. - ssh(1): add a "match localnetwork" predicate. This allows matching on the addresses of available network interfaces and may be used to vary the effective client configuration based on network location. - ssh(1), sshd(8), ssh-keygen(1): infrastructure support for KRL extensions. This defines wire formats for optional KRL extensions and implements parsing of the new submessages. No actual extensions are supported at this point. - sshd(8): AuthorizedPrincipalsCommand and AuthorizedKeysCommand now accept two additional %-expansion sequences: %D which expands to the routing domain of the connected session and %C which expands to the addresses and port numbers for the source and destination of the connection. - ssh-keygen(1): increase the default work factor (rounds) for the bcrypt KDF used to derive symmetric encryption keys for passphrase protected key files by 50%. - ssh-agent(1): improve isolation between loaded PKCS#11 modules by running separate ssh-pkcs11-helpers for each loaded provider. - ssh(1): make -f (fork after authentication) work correctly with multiplexed connections, including ControlPersist (closes: #348741). - ssh(1): make ConnectTimeout apply to multiplexing sockets and not just to network connections. - ssh-agent(1), ssh(1): improve defences against invalid PKCS#11 modules being loaded by checking that the requested module contains the required symbol before loading it. - sshd(8): fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand appears before it in sshd_config. Since OpenSSH 8.7 the AuthorizedPrincipalsCommand directive was incorrectly ignored in this situation. - sshd(8), ssh(1), ssh-keygen(1): remove vestigial support for KRL signatures. When the KRL format was originally defined, it included support for signing of KRL objects. However, the code to sign KRLs and verify KRL signatues was never completed in OpenSSH. This release removes the partially-implemented code to verify KRLs. All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in KRL files. - All: fix a number of memory leaks and unreachable/harmless integer overflows. - ssh-agent(1), ssh(1): don't truncate strings logged from PKCS#11 modules. - sshd(8), ssh(1): better validate CASignatureAlgorithms in ssh_config and sshd_config. Previously this directive would accept certificate algorithm names, but these were unusable in practice as OpenSSH does not support CA chains. - ssh(1): make `ssh -Q CASignatureAlgorithms` only list signature algorithms that are valid for CA signing. Previous behaviour was to list all signing algorithms, including certificate algorithms. - ssh-keyscan(1): gracefully handle systems where rlimits or the maximum number of open files is larger than INT_MAX. - ssh-keygen(1): fix "no comment" not showing on when running `ssh-keygen -l` on multiple keys where one has a comment and other following keys do not. bz3580 - scp(1), sftp(1): adjust ftruncate() logic to handle servers that reorder requests. Previously, if the server reordered requests then the resultant file would be erroneously truncated. - ssh(1): don't incorrectly disable hostname canonicalization when CanonicalizeHostname=yes and ProxyJump was explicitly set to "none". - scp(1): when copying local->remote, check that the source file exists before opening an SFTP connection to the server (closes: #59255). - sshd(8): provide a replacement for the SELinux matchpathcon() function, which is deprecated. - All: relax libcrypto version checks for OpenSSL >=3 (closes: #1035623). Beyond OpenSSL 3.0, the ABI compatibility guarantees are wider (only the library major must match instead of major and minor in earlier versions). - ssh-copy-id(1): Special case OpenWrt instead of Dropbear (LP: #1966886). -- Colin Watson Sat, 02 Sep 2023 21:02:53 +0100 openssh (1:9.3p2-1) unstable; urgency=high * New upstream release (https://www.openssh.com/releasenotes.html#9.3p2): - [CVE-2023-38408] Fix a condition where specific libraries loaded via ssh-agent(1)'s PKCS#11 support could be abused to achieve remote code execution via a forwarded agent socket. -- Colin Watson Wed, 19 Jul 2023 22:49:14 +0100 openssh (1:9.3p1-1) unstable; urgency=medium * Debconf translations: - Romanian (thanks, Remus-Gabriel Chelu; closes: #1033178). * Properly fix date of 1:3.0.2p1-2 changelog entry (closes: #1034425). * New upstream release (https://www.openssh.com/releasenotes.html#9.3p1): - [CVE-2023-28531] ssh-add(1): when adding smartcard keys to ssh-agent(1) with the per-hop destination constraints (ssh-add -h ...) added in OpenSSH 8.9, a logic error prevented the constraints from being communicated to the agent. This resulted in the keys being added without constraints. The common cases of non-smartcard keys and keys without destination constraints are unaffected. This problem was reported by Luci Stanescu (closes: #1033166). - [SECURITY] ssh(1): Portable OpenSSH provides an implementation of the getrrsetbyname(3) function if the standard library does not provide it, for use by the VerifyHostKeyDNS feature. A specifically crafted DNS response could cause this function to perform an out-of-bounds read of adjacent stack data, but this condition does not appear to be exploitable beyond denial-of-service to the ssh(1) client. - ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256 when outputting SSHFP fingerprints to allow algorithm selection. - sshd(8): add a `sshd -G` option that parses and prints the effective configuration without attempting to load private keys and perform other checks. This allows usage of the option before keys have been generated and for configuration evaluation and verification by unprivileged users. - scp(1), sftp(1): fix progressmeter corruption on wide displays. - ssh-add(1), ssh-keygen(1): use RSA/SHA256 when testing usability of private keys as some systems are starting to disable RSA/SHA1 in libcrypto. - sftp-server(8): fix a memory leak. - ssh(1), sshd(8), ssh-keyscan(1): remove vestigial protocol compatibility code and simplify what's left. - Fix a number of low-impact Coverity static analysis findings. - ssh_config(5), sshd_config(5): mention that some options are not first-match-wins. - Rework logging for the regression tests. Regression tests will now capture separate logs for each ssh and sshd invocation in a test. - ssh(1): make `ssh -Q CASignatureAlgorithms` work as the manpage says it should. - ssh(1): ensure that there is a terminating newline when adding a new entry to known_hosts. - sshd(8): harden Linux seccomp sandbox. Move to an allowlist of mmap(2), madvise(2) and futex(2) flags, removing some concerning kernel attack surface. * debian/README.Debian: Clarify that you need to restart ssh.socket after overriding its ListenStream= option (LP: #2020560). * debian/openssh-server.postinst: Use "sshd -G" to parse the server configuration file (closes: #959726). * Fix incorrect RRSET_FORCE_EDNS0 flags validation in SSHFP DNSSEC patch (thanks, Ben Hutchings; closes: #909022). * Always use the internal mkdtemp implementation, since it substitutes more randomness into the template string than glibc's version (closes: #1001186). -- Colin Watson Tue, 20 Jun 2023 01:01:48 +0100 openssh (1:9.2p1-2) unstable; urgency=medium * Fix mistakenly-unreleased entry for 1:9.2p1-1 in debian/NEWS. -- Colin Watson Wed, 08 Feb 2023 10:43:07 +0000 openssh (1:9.2p1-1) unstable; urgency=medium * Set "UsePAM yes" when running regression tests, to match our default sshd configuration. * Ignore Lintian error about depending on lsb-base for now, to avoid problems with partial upgrades on non-default init systems. * New upstream release (https://www.openssh.com/releasenotes.html#9.2p1): - [SECURITY] sshd(8): fix a pre-authentication double-free memory fault introduced in OpenSSH 9.1. This is not believed to be exploitable, and it occurs in the unprivileged pre-auth process that is subject to chroot(2) and is further sandboxed on most major platforms. - [SECURITY] ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen option would ignore its first argument unless it was one of the special keywords "any" or "none", causing the permission list to fail open if only one permission was specified. - [SECURITY] ssh(1): if the CanonicalizeHostname and CanonicalizePermittedCNAMEs options were enabled, and the system/libc resolver did not check that names in DNS responses were valid, then use of these options could allow an attacker with control of DNS to include invalid characters (possibly including wildcards) in names added to known_hosts files when they were updated. These names would still have to match the CanonicalizePermittedCNAMEs allow-list, so practical exploitation appears unlikely. - ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that controls whether the client-side ~C escape sequence that provides a command-line is available. Among other things, the ~C command-line could be used to add additional port-forwards at runtime. This option defaults to "no", disabling the ~C command-line that was previously enabled by default. - sshd(8): add support for channel inactivity timeouts via a new sshd_config(5) ChannelTimeout directive. This allows channels that have not seen traffic in a configurable interval to be automatically closed. Different timeouts may be applied to session, X11, agent and TCP forwarding channels. - sshd(8): add a sshd_config UnusedConnectionTimeout option to terminate client connections that have no open channels for a length of time. This complements the ChannelTimeout option above. - sshd(8): add a -V (version) option to sshd like the ssh client has. - ssh(1): add a "Host" line to the output of ssh -G showing the original hostname argument. bz3343 - scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to allow control over some SFTP protocol parameters: the copy buffer length and the number of in-flight requests, both of which are used during upload/download. Previously these could be controlled in sftp(1) only. This makes them available in both SFTP protocol clients using the same option character sequence. - ssh-keyscan(1): allow scanning of complete CIDR address ranges, e.g. "ssh-keyscan 192.168.0.0/24". If a CIDR range is passed, then it will be expanded to all possible addresses in the range including the all-0s and all-1s addresses. - ssh(1): support dynamic remote port forwarding in escape command-line's -R processing. - ssh(1): when restoring non-blocking mode to stdio fds, restore exactly the flags that ssh started with and don't just clobber them with zero, as this could also remove the append flag from the set. - ssh(1): avoid printf("%s", NULL) if using UserKnownHostsFile=none and a hostkey in one of the system known hosts file changes. - scp(1): switch scp from using pipes to a socket-pair for communication with its ssh sub-processes, matching how sftp(1) operates. - sshd(8): clear signal mask early in main(); sshd may have been started with one or more signals masked (sigprocmask(2) is not cleared on fork/exec) and this could interfere with various things, e.g. the login grace timer. Execution environments that fail to clear the signal mask before running sshd are clearly broken, but apparently they do exist. - ssh(1): warn if no host keys for hostbased auth can be loaded. - sshd(8): Add server debugging for hostbased auth that is queued and sent to the client after successful authentication, but also logged to assist in diagnosis of HostbasedAuthentication problems. - ssh(1): document use of the IdentityFile option as being usable to list public keys as well as private keys. - sshd(8): check for and disallow MaxStartups values less than or equal to zero during config parsing, rather than failing later at runtime. - ssh-keygen(1): fix parsing of hex cert expiry times specified on the command-line when acting as a CA. - scp(1): when scp(1) is using the SFTP protocol for transport (the default), better match scp/rcp's handling of globs that don't match the globbed characters but do match literally (e.g. trying to transfer a file named "foo.[1]"). Previously scp(1) in SFTP mode would not match these pathnames but legacy scp/rcp mode would. - ssh-agent(1): document the "-O no-restrict-websafe" command-line option. - ssh(1): honour user's umask(2) if it is more restrictive then the ssh default (022). - sshd(8): allow writev(2) in the Linux seccomp sandbox. This seems to be used by recent glibcs at least in some configurations during error conditions. - sshd(8): simplify handling of SSH_CONNECTION PAM env var, removing global variable and checking the return value from pam_putenv. - sshd(8): disable SANDBOX_SECCOMP_FILTER_DEBUG that was mistakenly enabled during the OpenSSH 9.1 release cycle. - sshd(8): defer PRNG seeding until after the initial closefrom(2) call. PRNG seeding will initialize OpenSSL, and some engine providers (e.g. Intel's QAT) will open descriptors for their own use that closefrom(2) could clobber. * debian/run-tests: Add a little more flexibility for debugging. -- Colin Watson Wed, 08 Feb 2023 10:36:06 +0000 openssh (1:9.1p1-2) unstable; urgency=medium [ Christian Göttsche ] * Do not copy SELinux security context in postinst.

Previously if an environment variable was multiply specified the last set value would have been used. - ssh-keygen(8): ssh-keygen -A (generate all default host key types) will no longer generate DSA keys, as these are insecure and have not been used by default for some years. - ssh(1), sshd(8): add a RequiredRSASize directive to set a minimum RSA key length. Keys below this length will be ignored for user authentication and for host authentication in sshd(8). ssh(1) will terminate a connection if the server offers an RSA key that falls below this limit, as the SSH protocol does not include the ability to retry a failed key exchange. - sftp-server(8): add a "users-groups-by-id@openssh.com" extension request that allows the client to obtain user/group names that correspond to a set of uids/gids. - sftp(1): use "users-groups-by-id@openssh.com" sftp-server extension (when available) to fill in user/group names for directory listings. - sftp-server(8): support the "home-directory" extension request defined in draft-ietf-secsh-filexfer-extensions-00. This overlaps a bit with the existing "expand-path@openssh.com", but some other clients support it. - ssh-keygen(1), sshd(8): allow certificate validity intervals, sshsig verification times and authorized_keys expiry-time options to accept dates in the UTC time zone in addition to the default of interpreting them in the system time zone. YYYYMMDD and YYMMDDHHMM[SS] dates/times will be interpreted as UTC if suffixed with a 'Z' character. Also allow certificate validity intervals to be specified in raw seconds-since-epoch as hex value, e.g. -V 0x1234:0x4567890. This is intended for use by regress tests and other tools that call ssh-keygen as part of a CA workflow. - sftp(1): allow arguments to the sftp -D option, e.g. sftp -D "/usr/libexec/sftp-server -el debug3". - ssh-keygen(1): allow the existing -U (use agent) flag to work with "-Y sign" operations, where it will be interpreted to require that the private keys is hosted in an agent. - ssh-keygen(1): implement the "verify-required" certificate option. This was already documented when support for user-verified FIDO keys was added, but the ssh-keygen(1) code was missing. - ssh-agent(1): hook up the restrict_websafe command-line flag; previously the flag was accepted but never actually used. - sftp(1): improve filename tab completions: never try to complete names to non-existent commands, and better match the completion type (local or remote filename) against the argument position being completed. - ssh-keygen(1), ssh(1), ssh-agent(1): several fixes to FIDO key handling, especially relating to keys that request user-verification. These should reduce the number of unnecessary PIN prompts for keys that support intrinsic user verification. - ssh-keygen(1): when enrolling a FIDO resident key, check if a credential with matching application and user ID strings already exists and, if so, prompt the user for confirmation before overwriting the credential. - sshd(8): improve logging of errors when opening authorized_keys files. - ssh(1): avoid multiplexing operations that could cause SIGPIPE from causing the client to exit early. - ssh_config(5), sshd_config(5): clarify that the RekeyLimit directive applies to both transmitted and received data. - ssh-keygen(1): avoid double fclose() in error path. - sshd(8): log an error if pipe() fails while accepting a connection. - ssh-keyscan(1): add missing *-sk types to ssh-keyscan manpage. - sshd(8): ensure that authentication passwords are cleared from memory in error paths. - ssh(1), ssh-agent(1): avoid possibility of notifier code executing kill(-1). - ssh_config(5): note that the ProxyJump directive also accepts the same tokens as ProxyCommand. - scp(1): do not ftruncate(3) files early when in sftp mode. The previous behaviour of unconditionally truncating the destination file would cause "scp ~/foo localhost:foo" and the reverse "scp localhost:foo ~/foo" to delete all the contents of their destination. - ssh-keygen(1): improve error message when 'ssh-keygen -Y sign' is unable to load a private key. - sftp(1), scp(1): when performing operations that glob(3) a remote path, ensure that the implicit working directory used to construct that path escapes glob(3) characters. This prevents glob characters from being processed in places they shouldn't, e.g. "cd /tmp/a*/", "get *.txt" should have the get operation treat the path "/tmp/a*" literally and not attempt to expand it (LP: #1483751). - ssh(1), sshd(8): be stricter in which characters will be accepted in specifying a mask length; allow only 0-9. - ssh-keygen(1): avoid printing hash algorithm twice when dumping a KRL. - ssh(1), sshd(8): continue running local I/O for open channels during SSH transport rekeying. This should make ~-escapes work in the client (e.g. to exit) if the connection happened to have stalled during a rekey event. - ssh(1), sshd(8): avoid potential poll() spin during rekeying. - Further hardening for sshbuf internals: disallow "reparenting" a hierarchical sshbuf and zero the entire buffer if reallocation fails. - sshd(8): add AUDIT_ARCH_PPC to supported seccomp sandbox architectures. * Drop patch to work around https://twistedmatrix.com/trac/ticket/9765, since the fix for that is in Debian testing. * Rewrite gnome-ssh-askpass(1) manual page using mdoc macros, and flesh it out a bit more. [ Steve Langasek ] * Support systemd socket activation. Migrate any existing inetd-style socket activation to systemd socket activation. [ Gioele Barabucci ] * Remove ancient version constraints. * d/openssh-server.{postinst,config}: get_config_option: Replace perl with sed. -- Colin Watson Mon, 14 Nov 2022 16:25:45 +0000 openssh (1:9.0p1-1) unstable; urgency=medium * New upstream release (https://www.openssh.com/releasenotes.html#9.0p1): - scp(1): Use the SFTP protocol by default (closes: #144579, #204546, #327019). This changes scp's quoting semantics by no longer performing wildcard expansion using the remote shell, and (with some server versions) no longer expanding ~user paths. The -O option is available to use the old protocol. See NEWS.Debian for more details. - ssh(1), sshd(8): use the hybrid Streamlined NTRU Prime + x25519 key exchange method by default ("sntrup761x25519-sha512@openssh.com"). The NTRU algorithm is believed to resist attacks enabled by future quantum computers and is paired with the X25519 ECDH key exchange (the previous default) as a backstop against any weaknesses in NTRU Prime that may be discovered in the future. The combination ensures that the hybrid exchange offers at least as good security as the status quo. - sftp-server(8): support the "copy-data" extension to allow server- side copying of files/data, following the design in draft-ietf-secsh-filexfer-extensions-00. - sftp(1): add a "cp" command to allow the sftp client to perform server-side file copies. - ssh(1), sshd(8): upstream: fix poll(2) spin when a channel's output fd closes without data in the channel buffer (closes: #1007822). - sshd(8): pack pollfd array in server listen/accept loop. Could cause the server to hang/spin when MaxStartups > RLIMIT_NOFILE. - ssh-keygen(1): avoid NULL deref via the find-principals and check-novalidate operations. bz3409 and GHPR307 respectively. - scp(1): fix a memory leak in argument processing. - sshd(8): don't try to resolve ListenAddress directives in the sshd re-exec path. They are unused after re-exec and parsing errors (possible for example if the host's network configuration changed) could prevent connections from being accepted. - sshd(8): when refusing a public key authentication request from a client for using an unapproved or unsupported signature algorithm include the algorithm name in the log message to make debugging easier. - ssh(1), sshd(8): Fix possible integer underflow in scan_scaled(3) parsing of K/M/G/etc quantities. - sshd(8): default to not using sandbox when cross compiling. On most systems poll(2) does not work when the number of FDs is reduced with setrlimit, so assume it doesn't when cross compiling and we can't run the test. * Remove obsolete FAQ, removed from openssh.com in 2016. -- Colin Watson Sat, 09 Apr 2022 14:14:10 +0100 openssh (1:8.9p1-3) unstable; urgency=medium * Allow ppoll_time64 in seccomp filter (closes: #1006445). -- Colin Watson Fri, 25 Feb 2022 23:30:49 +0000 openssh (1:8.9p1-2) unstable; urgency=medium * Improve detection of -fzero-call-used-regs=all support. -- Colin Watson Thu, 24 Feb 2022 16:09:56 +0000 openssh (1:8.9p1-1) unstable; urgency=medium * New upstream release (https://www.openssh.com/releasenotes.html#8.9p1): - sshd(8): fix an integer overflow in the user authentication path that, in conjunction with other logic errors, could have yielded unauthenticated access under difficult to exploit conditions. - sshd(8), portable OpenSSH only: this release removes in-built support for MD5-hashed passwords. - ssh(1), sshd(8), ssh-add(1), ssh-agent(1): add a system for restricting forwarding and use of keys added to ssh-agent(1). - ssh(1), sshd(8): add the sntrup761x25519-sha512@openssh.com hybrid ECDH/x25519 + Streamlined NTRU Prime post-quantum KEX to the default KEXAlgorithms list (after the ECDH methods but before the prime-group DH ones). The next release of OpenSSH is likely to make this key exchange the default method. - ssh-keygen(1): when downloading resident keys from a FIDO token, pass back the user ID that was used when the key was created and append it to the filename the key is written to (if it is not the default). Avoids keys being clobbered if the user created multiple resident keys with the same application string but different user IDs. - ssh-keygen(1), ssh(1), ssh-agent(1): better handling for FIDO keys on tokens that provide user verification (UV) on the device itself, including biometric keys, avoiding unnecessary PIN prompts. - ssh-keygen(1): add "ssh-keygen -Y match-principals" operation to perform matching of principals names against an allowed signers file. To be used towards a TOFU model for SSH signatures in git. - ssh-add(1), ssh-agent(1): allow pin-required FIDO keys to be added to ssh-agent(1). $SSH_ASKPASS will be used to request the PIN at authentication time. - ssh-keygen(1): allow selection of hash at sshsig signing time (either sha512 (default) or sha256). - ssh(1), sshd(8): read network data directly to the packet input buffer instead indirectly via a small stack buffer. Provides a modest performance improvement. - ssh(1), sshd(8): read data directly to the channel input buffer, providing a similar modest performance improvement. - ssh(1): extend the PubkeyAuthentication configuration directive to accept yes|no|unbound|host-bound to allow control over one of the protocol extensions used to implement agent-restricted keys. - sshd(8): document that CASignatureAlgorithms, ExposeAuthInfo and PubkeyAuthOptions can be used in a Match block. - sshd(8): fix possible string truncation when constructing paths to .rhosts/.shosts files with very long user home directory names. - ssh-keysign(1): unbreak for KEX algorithms that use SHA384/512 exchange hashes. - ssh(1): don't put the TTY into raw mode when SessionType=none, avoids ^C being unable to kill such a session. - scp(1): fix some corner-case bugs in SFTP-mode handling of ~-prefixed paths. - ssh(1): unbreak hostbased auth using RSA keys. Allow ssh(1) to select RSA keys when only RSA/SHA2 signature algorithms are configured (this is the default case). Previously RSA keys were not being considered in the default case. - ssh-keysign(1): make ssh-keysign use the requested signature algorithm and not the default for the key type. Part of unbreaking hostbased auth for RSA/SHA2 keys. - ssh(1): stricter UpdateHostkey signature verification logic on the client-side. Require RSA/SHA2 signatures for RSA hostkeys except when RSA/SHA1 was explicitly negotiated during initial KEX. - ssh(1), sshd(8): fix signature algorithm selection logic for UpdateHostkeys on the server side. The previous code tried to prefer RSA/SHA2 for hostkey proofs of RSA keys, but missed some cases. This will use RSA/SHA2 signatures for RSA keys if the client proposed these algorithms in initial KEX. - All: convert all uses of select(2)/pselect(2) to poll(2)/ppoll(2). This includes the mainloops in ssh(1), ssh-agent(1), ssh-agent(1) and sftp-server(8), as well as the sshd(8) listen loop and all other FD read/writability checks. On platforms with missing or broken poll(2)/ppoll(2) syscalls a select(2)-based compat shim is available. - ssh-keygen(1): the "-Y find-principals" command was verifying key validity when using ca certs but not with simple key lifetimes within the allowed signers file. - ssh-keygen(1): make sshsig verify-time argument parsing optional. - sshd(8): fix truncation in rhosts/shosts path construction. - ssh(1), ssh-agent(1): avoid xmalloc(0) for PKCS#11 keyid for ECDSA keys (we already did this for RSA keys). Avoids fatal errors for PKCS#11 libraries that return empty keyid, e.g. Microchip ATECC608B "cryptoauthlib". - ssh(1), ssh-agent(1): improve the testing of credentials against inserted FIDO: ask the token whether a particular key belongs to it in cases where the token supports on-token user-verification (e.g. biometrics) rather than just assuming that it will accept it. Will reduce spurious "Confirm user presence" notifications for key handles that relate to FIDO keys that are not currently inserted in at least some cases. - ssh(1), sshd(8): correct value for IPTOS_DSCP_LE. It needs to allow for the preceding two ECN bits. - ssh-keygen(1): add missing -O option to usage() for the "-Y sign" option. - ssh-keygen(1): fix a NULL deref when using the find-principals function, when matching an allowed_signers line that contains a namespace restriction, but no restriction specified on the command-line - ssh-agent(1): fix memleak in process_extension(). - ssh(1): suppress "Connection to xxx closed" messages when LogLevel is set to "error" or above. - ssh(1), sshd(8): use correct zlib flags when inflate(3)-ing compressed packet data. - scp(1): when recursively transferring files in SFTP mode, create the destination directory if it doesn't already exist to match scp(1) in legacy RCP mode behaviour. - scp(1): many improvements in error message consistency between scp(1) in SFTP mode vs legacy RCP mode. - sshd(8): fix potential race in SIGTERM handling. - ssh(1), ssh(8): since DSA keys are deprecated, move them to the end of the default list of public keys so that they will be tried last. - ssh-keygen(1): allow 'ssh-keygen -Y find-principals' to match wildcard principals in allowed_signers files. - ssh(1), sshd(8): don't trust closefrom(2) on Linux. glibc's implementation does not work in a chroot when the kernel does not have close_range(2). It tries to read from /proc/self/fd and when that fails dies with an assertion of sorts. Instead, call close_range(2) directly from our compat code and fall back if that fails. - Correct handling of exceptfds/POLLPRI in our select(2)-based poll(2)/ppoll(2) compat implementation. * Drop patch to work around https://twistedmatrix.com/trac/ticket/9515, since the fix for that is in Debian stable. -- Colin Watson Thu, 24 Feb 2022 11:06:15 +0000 openssh (1:8.8p1-1) unstable; urgency=medium * New upstream release (https://www.openssh.com/releasenotes.html#8.8p1, closes: #996391): - This release disables RSA signatures using the SHA-1 hash algorithm by default. (Existing RSA keys may still be used and do not need to be replaced; see NEWS.Debian if you have problems connecting to old SSH servers.) - ssh(1): allow the ssh_config(5) CanonicalizePermittedCNAMEs directive to accept a "none" argument to specify the default behaviour. - scp(1): when using the SFTP protocol, continue transferring files after a transfer error occurs, better matching original scp/rcp behaviour. - ssh(1): fixed a number of memory leaks in multiplexing, - ssh-keygen(1): avoid crash when using the -Y find-principals command. - A number of documentation and manual improvements. - ssh(1)/sshd(8): some fixes to the pselect(2) replacement compatibility code. * Work around missing RSA SHA-2 signature support in conch until the upstream fix lands in Debian. -- Colin Watson Tue, 15 Feb 2022 19:20:21 +0000 openssh (1:8.7p1-4) unstable; urgency=medium [ Daniel Baumann ] * Fix typo in openssh-client.alternatives (closes: #1002803).

This was previously available via the -3 flag. A -R flag has been added to select the old behaviour. - ssh(1)/sshd(8): both the client and server are now using a stricter configuration file parser. - ssh(1): when using SSHFP DNS records for host key verification, ssh(1) will verify all matching records instead of just those with the specific signature type requested. - ssh-keygen(1): when generating a FIDO key and specifying an explicit attestation challenge (using -Ochallenge), the challenge will now be hashed by the builtin security key middleware. - sshd(8): environment="..." directives in authorized_keys files are now first-match-wins and limited to 1024 discrete environment variable names. - scp(1): experimental support for transfers using the SFTP protocol as a replacement for the venerable SCP/RCP protocol that it has traditionally used. SFTP offers more predictable filename handling and does not require expansion of glob(3) patterns via the shell on the remote side. SFTP support may be enabled via a temporary scp -s flag. It is intended for SFTP to become the default transfer mode in the near future, at which time the -s flag will be removed. The -O flag exists to force use of the original SCP/RCP protocol for cases where SFTP may be unavailable or incompatible. - sftp-server(8): add a protocol extension to support expansion of ~/ and ~user/ prefixed paths. This was added to support these paths when used by scp(1) while in SFTP mode. - ssh(1): add a ForkAfterAuthentication ssh_config(5) counterpart to the ssh(1) -f flag. GHPR231 - ssh(1): add a StdinNull directive to ssh_config(5) that allows the config file to do the same thing as -n does on the ssh(1) command- line. GHPR231 - ssh(1): add a SessionType directive to ssh_config, allowing the configuration file to offer equivalent control to the -N (no session) and -s (subsystem) command-line flags (closes: #609122). - ssh-keygen(1): allowed signers files used by ssh-keygen(1) signatures now support listing key validity intervals alongside they key, and ssh-keygen(1) can optionally check during signature verification whether a specified time falls inside this interval. This feature is intended for use by git to support signing and verifying objects using ssh keys. - ssh-keygen(8): support printing of the full public key in a sshsig signature via a -Oprint-pubkey flag. - ssh(1)/sshd(8): start time-based re-keying exactly on schedule in the client and server mainloops. Previously the re-key timeout could expire but re-keying would not start until a packet was sent or received, causing a spin in select() if the connection was quiescent. - ssh-keygen(1): avoid Y2038 problem in printing certificate validity lifetimes. Dates past 2^31-1 seconds since epoch were displayed incorrectly on some platforms. - scp(1): allow spaces to appear in usernames for local to remote and scp -3 remote to remote copies. - ssh(1)/sshd(8): remove references to ChallengeResponseAuthentication in favour of KbdInteractiveAuthentication. The former is what was in SSHv1, the latter is what is in SSHv2 (RFC4256) and they were treated as somewhat but not entirely equivalent. We retain the old name as a deprecated alias so configuration files continue to work as well as a reference in the man page for people looking for it. - ssh(1)/ssh-add(1)/ssh-keygen(1): fix decoding of X.509 subject name when extracting a key from a PKCS#11 certificate. - ssh(1): restore blocking status on stdio fds before close. ssh(1) needs file descriptors in non-blocking mode to operate but it was not restoring the original state on exit. This could cause problems with fds shared with other programs via the shell. - ssh(1)/sshd(8): switch both client and server mainloops from select(3) to pselect(3). Avoids race conditions where a signal may arrive immediately before select(3) and not be processed until an event fires. - ssh(1): sessions started with ControlPersist were incorrectly executing a shell when the -N (no shell) option was specified (closes: #762633). - ssh(1): check if IPQoS or TunnelDevice are already set before overriding. Prevents values in config files from overriding values supplied on the command line. - ssh(1): fix debug message when finding a private key to match a certificate being attempted for user authentication. Previously it would print the certificate's path, whereas it was supposed to be showing the private key's path. - sshd(8): match host certificates against host public keys, not private keys. Allows use of certificates with private keys held in a ssh-agent. - ssh(1): add a workaround for a bug in OpenSSH 7.4 sshd(8), which allows RSA/SHA2 signatures for public key authentication but fails to advertise this correctly via SSH2_MSG_EXT_INFO. This causes clients of these server to incorrectly match PubkeyAcceptedAlgorithms and potentially refuse to offer valid keys. - sftp(1)/scp(1): degrade gracefully if a sftp-server offers the limits@openssh.com extension but fails when the client tries to invoke it. - ssh(1): allow ssh_config SetEnv to override $TERM, which is otherwise handled specially by the protocol. Useful in ~/.ssh/config to set TERM to something generic (e.g. "xterm" instead of "xterm-256color") for destinations that lack terminfo entries. - sftp-server(8): the limits@openssh.com extension was incorrectly marked as an operation that writes to the filesystem, which made it unavailable in sftp-server read-only mode. - ssh(1): fix SEGV in UpdateHostkeys debug() message, triggered when the update removed more host keys than remain present. - Many manual page fixes. - sshd(8): handle GIDs > 2^31 in getgrouplist. When compiled in 32bit mode, the getgrouplist implementation may fail for GIDs greater than LONG_MAX. - ssh(1): xstrdup environment variable used by ForwardAgent. - sshd(8): don't sigdie() in signal handler in privsep child process; this can end up causing sandbox violations. * New upstream release (https://www.openssh.com/releasenotes.html#8.6p1): - sftp-server(8): add a new limits@openssh.com protocol extension that allows a client to discover various server limits, including maximum packet size and maximum read/write length. - sftp(1): use the new limits@openssh.com extension (when available) to select better transfer lengths in the client. - sshd(8): Add ModuliFile keyword to sshd_config to specify the location of the "moduli" file containing the groups for DH-GEX. - ssh_config(5), sshd_config(5): sync CASignatureAlgorithms lists in manual pages with the current default. - ssh(1): ensure that pkcs11_del_provider() is called before exit. - ssh(1), sshd(8): fix problems in string->argv conversion. Multiple backslashes were not being dequoted correctly and quoted space in the middle of a string was being incorrectly split. - ssh(1): return non-zero exit status when killed by signal. - sftp-server(8): increase maximum SSH2_FXP_READ to match the maximum packet size. Also handle zero-length reads that are not explicitly banned by the spec. - sshd(8): don't mistakenly exit on transient read errors on the network socket (e.g. EINTR, EAGAIN). - Create a dedicated contrib/gnome-ssk-askpass3.c source instead of building it from the same file as used for GNOME2. Use the GNOME3 gdk_seat_grab() to manage keyboard/mouse/server grabs for better compatibility with Wayland. - sshd(8): soft-disallow the fstatat64 syscall in the Linux seccomp-bpf sandbox. * New upstream release (https://www.openssh.com/releasenotes.html#8.5p1): - ssh(1), sshd(8): change the first-preference signature algorithm from ECDSA to ED25519. - ssh(1), sshd(8): set the TOS/DSCP specified in the configuration for interactive use prior to TCP connect. - ssh(1), sshd(8): remove the pre-standardization cipher rijndael-cbc@lysator.liu.se. - ssh(1), sshd(8): update/replace the experimental post-quantum hybrid key exchange method based on Streamlined NTRU Prime coupled with X25519. - ssh(1): disable CheckHostIP by default. It provides insignificant benefits while making key rotation significantly more difficult, especially for hosts behind IP-based load-balancers (closes: #764027). - ssh(1): enable UpdateHostkeys by default subject to some conservative preconditions (closes: #875532): + The key was matched in the UserKnownHostsFile (and not in the GlobalKnownHostsFile). + The same key does not exist under another name. + A certificate host key is not in use. + known_hosts contains no matching wildcard hostname pattern. + VerifyHostKeyDNS is not enabled. + The default UserKnownHostsFile is in use. We expect some of these conditions will be modified or relaxed in future. - ssh(1), sshd(8): add a new LogVerbose configuration directive that allows forcing maximum debug logging by file/function/line pattern-lists. - ssh(1): when prompting the user to accept a new hostkey, display any other host names/addresses already associated with the key. - ssh(1): allow UserKnownHostsFile=none to indicate that no known_hosts file should be used to identify host keys. - ssh(1): add a ssh_config KnownHostsCommand option that allows the client to obtain known_hosts data from a command in addition to the usual files. - ssh(1): add a ssh_config PermitRemoteOpen option that allows the client to restrict the destination when RemoteForward is used with SOCKS. - ssh(1): for FIDO keys, if a signature operation fails with a "incorrect PIN" reason and no PIN was initially requested from the user, then request a PIN and retry the operation. This supports some biometric devices that fall back to requiring PIN when reading of the biometric failed, and devices that require PINs for all hosted credentials. - sshd(8): implement client address-based rate-limiting via new sshd_config(5) PerSourceMaxStartups and PerSourceNetBlockSize directives that provide more fine-grained control on a per-origin address basis than the global MaxStartups limit. - ssh(1): Prefix keyboard interactive prompts with "(user@host)" to make it easier to determine which connection they are associated with in cases like scp -3, ProxyJump, etc. (closes: #343267). - sshd(8): fix sshd_config SetEnv directives located inside Match blocks. - ssh(1): when requesting a FIDO token touch on stderr, inform the user once the touch has been recorded. - ssh(1): prevent integer overflow when ridiculously large ConnectTimeout values are specified, capping the effective value (for most platforms) at 24 days. - ssh(1): consider the ECDSA key subtype when ordering host key algorithms in the client. - ssh(1), sshd(8): rename the PubkeyAcceptedKeyTypes keyword to PubkeyAcceptedAlgorithms. The previous name incorrectly suggested that it control allowed key algorithms, when this option actually specifies the signature algorithms that are accepted. The previous name remains available as an alias (closes: #933665). - ssh(1), sshd(8): similarly, rename HostbasedKeyTypes (ssh) and HostbasedAcceptedKeyTypes (sshd) to HostbasedAcceptedAlgorithms. - sftp-server(8): add missing lsetstat@openssh.com documentation and advertisement in the server's SSH2_FXP_VERSION hello packet. - ssh(1), sshd(8): more strictly enforce KEX state-machine by banning packet types once they are received. Fixes memleak caused by duplicate SSH2_MSG_KEX_DH_GEX_REQUEST. - sftp(1): allow the full range of UIDs/GIDs for chown/chgrp on 32bit platforms instead of being limited by LONG_MAX. - Minor man page fixes (capitalization, commas, etc.) - sftp(1): when doing an sftp recursive upload or download of a read-only directory, ensure that the directory is created with write and execute permissions in the interim so that the transfer can actually complete, then set the directory permission as the final step. - ssh-keygen(1): document the -Z, check the validity of its argument earlier and provide a better error message if it's not correct. - ssh(1): ignore comments at the end of config lines in ssh_config, similar to what we already do for sshd_config. - sshd_config(5): mention that DisableForwarding is valid in a sshd_config Match block. - sftp(1): fix incorrect sorting of "ls -ltr" under some circumstances. - ssh(1), sshd(8): fix potential integer truncation of (unlikely) timeout values. - ssh(1): make hostbased authentication send the signature algorithm in its SSH2_MSG_USERAUTH_REQUEST packets instead of the key type. This make HostbasedAcceptedAlgorithms do what it is supposed to - filter on signature algorithm and not key type. - sshd(8): add a number of platform-specific syscalls to the Linux seccomp-bpf sandbox. - sshd(8): remove debug message from sigchld handler that could cause deadlock on some platforms. - Sync contrib/ssh-copy-id with upstream. * Remove OpenBSD-specific rdomain references from sshd_config(5) (closes: #998069). * Define MAXHOSTNAMELEN on GNU/Hurd (thanks, Svante Signell; closes: #997030). * Build-depend on libelogind-dev as an alternative to libsystemd-dev on Linux (thanks, Svante Signell; closes: #997035). * Backport from upstream: - CVE-2021-41617 (closes: #995130): sshd(8) from OpenSSH 6.2 through 8.7 failed to correctly initialise supplemental groups when executing an AuthorizedKeysCommand or AuthorizedPrincipalsCommand, where a AuthorizedKeysCommandUser or AuthorizedPrincipalsCommandUser directive has been set to run the command as a different user.

It now includes the authenticator data needed to validate attestation signatures. - The API between OpenSSH and the FIDO token middleware has changed and the SSH_SK_VERSION_MAJOR version has been incremented as a result. Third-party middleware libraries must support the current API version (7) to work with OpenSSH 8.4. - ssh(1), ssh-keygen(1): support for FIDO keys that require a PIN for each use. These keys may be generated using ssh-keygen using a new "verify-required" option. When a PIN-required key is used, the user will be prompted for a PIN to complete the signature operation. - sshd(8): authorized_keys now supports a new "verify-required" option to require FIDO signatures assert that the token verified that the user was present before making the signature. The FIDO protocol supports multiple methods for user-verification, but currently OpenSSH only supports PIN verification. - sshd(8), ssh-keygen(1): add support for verifying FIDO webauthn signatures. Webauthn is a standard for using FIDO keys in web browsers. These signatures are a slightly different format to plain FIDO signatures and thus require explicit support. - ssh(1): allow some keywords to expand shell-style ${ENV} environment variables. The supported keywords are CertificateFile, ControlPath, IdentityAgent and IdentityFile, plus LocalForward and RemoteForward when used for Unix domain socket paths. - ssh(1), ssh-agent(1): allow some additional control over the use of ssh-askpass via a new $SSH_ASKPASS_REQUIRE environment variable, including forcibly enabling and disabling its use (closes: #368657). - ssh(1): allow ssh_config(5)'s AddKeysToAgent keyword accept a time limit for keys in addition to its current flag options. Time-limited keys will automatically be removed from ssh-agent after their expiry time has passed. - scp(1), sftp(1): allow the -A flag to explicitly enable agent forwarding in scp and sftp. The default remains to not forward an agent, even when ssh_config enables it. - ssh(1): add a '%k' TOKEN that expands to the effective HostKey of the destination. This allows, e.g., keeping host keys in individual files using "UserKnownHostsFile ~/.ssh/known_hosts.d/%k" (closes: #481250). - ssh(1): add %-TOKEN, environment variable and tilde expansion to the UserKnownHostsFile directive, allowing the path to be completed by the configuration. - ssh-keygen(1): allow "ssh-add -d -" to read keys to be deleted from stdin. - sshd(8): improve logging for MaxStartups connection throttling. sshd will now log when it starts and stops throttling and periodically while in this state. - ssh(1), ssh-keygen(1): better support for multiple attached FIDO tokens. In cases where OpenSSH cannot unambiguously determine which token to direct a request to, the user is now required to select a token by touching it. In cases of operations that require a PIN to be verified, this avoids sending the wrong PIN to the wrong token and incrementing the token's PIN failure counter (tokens effectively erase their keys after too many PIN failures). - sshd(8): fix Include before Match in sshd_config (LP: #1885990). - ssh(1): close stdin/out/error when forking after authentication completes ("ssh -f ..."). - ssh(1), sshd(8): limit the amount of channel input data buffered, avoiding peers that advertise large windows but are slow to read from causing high memory consumption. - ssh-agent(1): handle multiple requests sent in a single write() to the agent. - sshd(8): allow sshd_config longer than 256k. - sshd(8): avoid spurious "Unable to load host key" message when sshd load a private key but no public counterpart. - ssh(1): prefer the default hostkey algorithm list whenever we have a hostkey that matches its best-preference algorithm. - sshd(1): when ordering the hostkey algorithms to request from a server, prefer certificate types if the known_hosts files contain a key marked as a @cert-authority. - ssh(1): perform host key fingerprint comparisons for the "Are you sure you want to continue connecting (yes/no/[fingerprint])?" prompt with case sensitivity. - sshd(8): ensure that address/masklen mismatches in sshd_config yield fatal errors at daemon start time rather than later when they are evaluated. - ssh-keygen(1): ensure that certificate extensions are lexically sorted. Previously if the user specified a custom extension then the everything would be in order except the custom ones. - ssh(1): also compare username when checking for JumpHost loops. - ssh-keygen(1): preserve group/world read permission on known_hosts files across runs of "ssh-keygen -Rf /path". The old behaviour was to remove all rights for group/other. - ssh-keygen(1): Mention the [-a rounds] flag in the ssh-keygen manual page and usage(). - sshd(8): explicitly construct path to ~/.ssh/rc rather than relying on it being relative to the current directory, so that it can still be found if the shell startup changes its directory. - sshd(8): when redirecting sshd's log output to a file, undo this redirection after the session child process is forked(). Fixes missing log messages when using this feature under some circumstances. - sshd(8): start ClientAliveInterval bookkeeping before first pass through select() loop; fixed theoretical case where busy sshd may ignore timeouts from client. - ssh(1): only reset the ServerAliveInterval check when we receive traffic from the server and ignore traffic from a port forwarding client, preventing a client from keeping a connection alive when it should be terminated. - ssh-keygen(1): avoid spurious error message when ssh-keygen creates files outside ~/.ssh. - sftp-client(1): fix off-by-one error that caused sftp downloads to make one more concurrent request that desired. This prevented using sftp(1) in unpipelined request/response mode, which is useful when debugging. - ssh(1), sshd(8): handle EINTR in waitfd() and timeout_connect() helpers. - ssh(1), ssh-keygen(1): defer creation of ~/.ssh until we attempt to write to it so we don't leave an empty .ssh directory when it's not needed. - ssh(1), sshd(8): fix multiplier when parsing time specifications when handling seconds after other units. - sshd(8): always send any PAM account messages. If the PAM account stack returns any messages, always send them to the user and not just if the check succeeds. - gnome-ssh-askpass3: ensure the "close" button is not focused by default for SSH_ASKPASS_PROMPT=none prompts. Avoids space/enter accidentally dismissing FIDO touch notifications. - gnome-ssh-askpass3: allow some control over textarea colour via $GNOME_SSH_ASKPASS_FG_COLOR and $GNOME_SSH_ASKPASS_BG_COLOR environment variables. - Detect the Frankenstein monster of Linux/X32 and allow the sandbox to function there. -- Colin Watson Tue, 20 Oct 2020 14:15:17 +0100 openssh (1:8.3p1-1) unstable; urgency=medium * New upstream release (https://www.openssh.com/txt/release-8.3): - [SECURITY] scp(1): when receiving files, scp(1) could become desynchronised if a utimes(2) system call failed. This could allow file contents to be interpreted as file metadata and thereby permit an adversary to craft a file system that, when copied with scp(1) in a configuration that caused utimes(2) to fail (e.g. under a SELinux policy or syscall sandbox), transferred different file names and contents to the actual file system layout. - sftp(1): reject an argument of "-1" in the same way as ssh(1) and scp(1) do instead of accepting and silently ignoring it. - sshd(8): make IgnoreRhosts a tri-state option: "yes" to ignore rhosts/shosts, "no" to allow rhosts/shosts or (new) "shosts-only" to allow .shosts files but not .rhosts. - sshd(8): allow the IgnoreRhosts directive to appear anywhere in a sshd_config, not just before any Match blocks. - ssh(1): add %TOKEN percent expansion for the LocalForward and RemoteForward keywords when used for Unix domain socket forwarding. - all: allow loading public keys from the unencrypted envelope of a private key file if no corresponding public key file is present. - ssh(1), sshd(8): prefer to use chacha20 from libcrypto where possible instead of the (slower) portable C implementation included in OpenSSH. - ssh-keygen(1): add ability to dump the contents of a binary key revocation list via "ssh-keygen -lQf /path". - ssh(1): fix IdentitiesOnly=yes to also apply to keys loaded from a PKCS11Provider. - ssh-keygen(1): avoid NULL dereference when trying to convert an invalid RFC4716 private key. - scp(1): when performing remote-to-remote copies using "scp -3", start the second ssh(1) channel with BatchMode=yes enabled to avoid confusing and non-deterministic ordering of prompts. - ssh(1), ssh-keygen(1): when signing a challenge using a FIDO token, perform hashing of the message to be signed in the middleware layer rather than in OpenSSH code. This permits the use of security key middlewares that perform the hashing implicitly, such as Windows Hello. - ssh(1): fix incorrect error message for "too many known hosts files." - ssh(1): make failures when establishing "Tunnel" forwarding terminate the connection when ExitOnForwardFailure is enabled. - ssh-keygen(1): fix printing of fingerprints on private keys and add a regression test for same. - sshd(8): document order of checking AuthorizedKeysFile (first) and AuthorizedKeysCommand (subsequently, if the file doesn't match). - sshd(8): document that /etc/hosts.equiv and /etc/shosts.equiv are not considered for HostbasedAuthentication when the target user is root. - ssh(1), ssh-keygen(1): fix NULL dereference in private certificate key parsing. - ssh(1), sshd(8): more consistency between sets of %TOKENS are accepted in various configuration options. - ssh(1), ssh-keygen(1): improve error messages for some common PKCS#11 C_Login failure cases. - ssh(1), sshd(8): make error messages for problems during SSH banner exchange consistent with other SSH transport-layer error messages and ensure they include the relevant IP addresses. - ssh-keygen(1), ssh-add(1): when downloading FIDO2 resident keys from a token, don't prompt for a PIN until the token has told us that it needs one. Avoids double-prompting on devices that implement on-device authentication (closes: #932071). - sshd(8), ssh-keygen(1): no-touch-required FIDO certificate option should be an extension, not a critical option. - ssh(1), ssh-keygen(1), ssh-add(1): offer a better error message when trying to use a FIDO key function and SecurityKeyProvider is empty. - ssh-add(1), ssh-agent(8): ensure that a key lifetime fits within the values allowed by the wire format (u32). Prevents integer wraparound of the timeout values. - ssh(1): detect and prevent trivial configuration loops when using ProxyJump. bz#3057. - On platforms that do not support setting process-wide routing domains (all excepting OpenBSD at present), fail to accept a configuration attempts to set one at process start time rather than fatally erroring at run time. - Fix theoretical infinite loop in the glob(3) replacement implementation. * Update GSSAPI key exchange patch from https://github.com/openssh-gsskex/openssh-gsskex: - Fix connection through ProxyJump in combination with "GSSAPITrustDNS yes". - Enable SHA2-based GSSAPI key exchange methods by default as RFC 8732 was published. * Fix or suppress various shellcheck errors under debian/. * Use AUTOPKGTEST_TMP rather than the deprecated ADTTMP. * Apply upstream patch to fix the handling of Port directives after Include (closes: #962035, LP: #1876320). -- Colin Watson Sun, 07 Jun 2020 13:44:04 +0100 openssh (1:8.2p1-4) unstable; urgency=medium * Add /etc/ssh/ssh_config.d/ to openssh-client. * Add /etc/ssh/sshd_config.d/ to openssh-server (closes: #952427). * Install ssh-sk-helper even on non-Linux architectures, though it will need an external middleware library in those cases. -- Colin Watson Wed, 26 Feb 2020 10:55:07 +0000 openssh (1:8.2p1-3) unstable; urgency=medium * Reupload with -sa to work around confusion with 1:8.2p1-1 being in NEW. -- Colin Watson Sun, 23 Feb 2020 13:30:01 +0000 openssh (1:8.2p1-2) unstable; urgency=medium * Move ssh-sk-helper into openssh-client rather than shipping it in a separate package.

Suggested by Bastian Blank. -- Colin Watson Sun, 23 Feb 2020 11:31:31 +0000 openssh (1:8.2p1-1) unstable; urgency=medium * New upstream release (https://www.openssh.com/txt/release-8.2, closes: #951582): - ssh(1), sshd(8), ssh-keygen(1): this release removes the "ssh-rsa" (RSA/SHA1) algorithm from those accepted for certificate signatures (i.e. the client and server CASignatureAlgorithms option) and will use the rsa-sha2-512 signature algorithm by default when the ssh-keygen(1) CA signs new certificates. - ssh(1), sshd(8): Remove diffie-hellman-group14-sha1 from the default key exchange proposal for both the client and server. - ssh-keygen(1): The command-line options related to the generation and screening of safe prime numbers used by the diffie-hellman-group-exchange-* key exchange algorithms have changed. Most options have been folded under the -O flag. - sshd(8): The sshd listener process title visible to ps(1) has changed to include information about the number of connections that are currently attempting authentication and the limits configured by MaxStartups. - Add support for FIDO/U2F hardware authenticators. - ssh-keygen(1): Add a "no-touch-required" option when generating FIDO-hosted keys, that disables their default behaviour of requiring a physical touch/tap on the token during authentication. Note: not all tokens support disabling the touch requirement. - sshd(8): Add a sshd_config PubkeyAuthOptions directive that collects miscellaneous public key authentication-related options for sshd(8). At present it supports only a single option "no-touch-required". This causes sshd to skip its default check for FIDO/U2F keys that the signature was authorised by a touch or press event on the token hardware. - ssh(1), sshd(8), ssh-keygen(1): Add a "no-touch-required" option for authorized_keys and a similar extension for certificates. This option disables the default requirement that FIDO key signatures attest that the user touched their key to authorize them, mirroring the similar PubkeyAuthOptions sshd_config option. - ssh-keygen(1): Add support for the writing the FIDO attestation information that is returned when new keys are generated via the "-O write-attestation=/path" option. FIDO attestation certificates may be used to verify that a FIDO key is hosted in trusted hardware. OpenSSH does not currently make use of this information, beyond optionally writing it to disk. - Add support for FIDO2 resident keys. - sshd(8): Add an Include sshd_config keyword that allows including additional configuration files via glob(3) patterns (closes: #631189). - ssh(1)/sshd(8): Make the LE (low effort) DSCP code point available via the IPQoS directive. - ssh(1): When AddKeysToAgent=yes is set and the key contains no comment, add the key to the agent with the key's path as the comment. - ssh-keygen(1), ssh-agent(1): Expose PKCS#11 key labels and X.509 subjects as key comments, rather than simply listing the PKCS#11 provider library path. - ssh-keygen(1): Allow PEM export of DSA and ECDSA keys. - sshd(8): When clients get denied by MaxStartups, send a notification prior to the SSH2 protocol banner according to RFC4253 section 4.2 (closes: #275458). - ssh(1), ssh-agent(1): When invoking the $SSH_ASKPASS prompt program, pass a hint to the program to describe the type of desired prompt. The possible values are "confirm" (indicating that a yes/no confirmation dialog with no text entry should be shown), "none" (to indicate an informational message only), or blank for the original ssh-askpass behaviour of requesting a password/phrase. - ssh(1): Allow forwarding a different agent socket to the path specified by $SSH_AUTH_SOCK, by extending the existing ForwardAgent option to accepting an explicit path or the name of an environment variable in addition to yes/no. - ssh-keygen(1): Add a new signature operations "find-principals" to look up the principal associated with a signature from an allowed-signers file. - sshd(8): Expose the number of currently-authenticating connections along with the MaxStartups limit in the process title visible to "ps". - sshd(8): Make ClientAliveCountMax=0 have sensible semantics: it will now disable connection killing entirely rather than the current behaviour of instantly killing the connection after the first liveness test regardless of success. - sshd(8): Clarify order of AllowUsers / DenyUsers vs AllowGroups / DenyGroups in the sshd(8) manual page. - sshd(8): Better describe HashKnownHosts in the manual page. - sshd(8): Clarify that that permitopen=/PermitOpen do no name or address translation in the manual page. - sshd(8): Allow the UpdateHostKeys feature to function when multiple known_hosts files are in use. When updating host keys, ssh will now search subsequent known_hosts files, but will add updated host keys to the first specified file only. - All: Replace all calls to signal(2) with a wrapper around sigaction(2). This wrapper blocks all other signals during the handler preventing races between handlers, and sets SA_RESTART which should reduce the potential for short read/write operations. - sftp(1): Fix a race condition in the SIGCHILD handler that could turn in to a kill(-1). - sshd(8): Fix a case where valid (but extremely large) SSH channel IDs were being incorrectly rejected. - ssh(1): When checking host key fingerprints as answers to new hostkey prompts, ignore whitespace surrounding the fingerprint itself. - All: Wait for file descriptors to be readable or writeable during non-blocking connect, not just readable. Prevents a timeout when the server doesn't immediately send a banner (e.g. multiplexers like sslh). - sshd_config(5): Document the sntrup4591761x25519-sha512@tinyssh.org key exchange algorithm. * Add more historical md5sums of /etc/ssh/sshd_config between 1:7.4p1-1 and 1:7.8p1-1 inclusive (closes: #951220). * ssh(1): Explain that -Y is equivalent to -X in the default configuration (closes: #951640). * Include /etc/ssh/ssh_config.d/*.conf from /etc/ssh/ssh_config and /etc/ssh/sshd_config.d/*.conf from /etc/ssh/sshd_config (closes: #845315). -- Colin Watson Fri, 21 Feb 2020 16:36:37 +0000 openssh (1:8.1p1-5) unstable; urgency=medium * Apply upstream patches to allow clock_nanosleep() and variants in the seccomp sandbox, fixing failures with glibc 2.31. * Apply upstream patch to deny (non-fatally) ipc in the seccomp sandbox, fixing failures with OpenSSL 1.1.1d and Linux < 3.19 on some architectures (closes: #946242). -- Colin Watson Sat, 11 Jan 2020 23:55:03 +0000 openssh (1:8.1p1-4) unstable; urgency=medium * Apply upstream patch to stop using 2020 as a future date in regress tests. -- Colin Watson Thu, 09 Jan 2020 11:42:10 +0000 openssh (1:8.1p1-3) unstable; urgency=medium [ Colin Watson ] * Drop suggestion of rssh, since it's been removed (see https://bugs.debian.org/923691).

This release encrypts private keys when they are not in use with a symmetric key that is derived from a relatively large "prekey" consisting of random data (currently 16KB). - ssh(1): Allow %n to be expanded in ProxyCommand strings. - ssh(1), sshd(8): Allow prepending a list of algorithms to the default set by starting the list with the '^' character, e.g. "HostKeyAlgorithms ^ssh-ed25519". - ssh-keygen(1): Add an experimental lightweight signature and verification ability. Signatures may be made using regular ssh keys held on disk or stored in a ssh-agent and verified against an authorized_keys-like list of allowed keys. Signatures embed a namespace that prevents confusion and attacks between different usage domains (e.g. files vs email). - ssh-keygen(1): Print key comment when extracting public key from a private key. - ssh-keygen(1): Accept the verbose flag when searching for host keys in known hosts (i.e. "ssh-keygen -vF host") to print the matching host's random-art signature too. - All: Support PKCS8 as an optional format for storage of private keys to disk. The OpenSSH native key format remains the default, but PKCS8 is a superior format to PEM if interoperability with non-OpenSSH software is required, as it may use a less insecure key derivation function than PEM's. - ssh(1): If a PKCS#11 token returns no keys then try to login and refetch them. - ssh(1): Produce a useful error message if the user's shell is set incorrectly during "match exec" processing. - sftp(1): Allow the maximum uint32 value for the argument passed to -b which allows better error messages from later validation. - ssh-keyscan(1): Include SHA2-variant RSA key algorithms in KEX proposal; allows ssh-keyscan to harvest keys from servers that disable old SHA1 ssh-rsa. - sftp(1): Print explicit "not modified" message if a file was requested for resumed download but was considered already complete. - sftp(1): Fix a typo and make move right to the closest end of a word just like moves left to the closest beginning of a word. - sshd(8): Cap the number of permitopen/permitlisten directives allowed to appear on a single authorized_keys line. - All: Fix a number of memory leaks (one-off or on exit paths). - ssh(1), sshd(8): Check for convtime() refusing to accept times that resolve to LONG_MAX. - ssh(1): Slightly more instructive error message when the user specifies multiple -J options on the command-line (closes: #929669). - ssh-agent(1): Process agent requests for RSA certificate private keys using correct signature algorithm when requested. - sftp(1): Check for user@host when parsing sftp target. This allows user@[1.2.3.4] to work without a path. - sshd(8): Enlarge format buffer size for certificate serial number so the log message can record any 64-bit integer without truncation. - sshd(8): For PermitOpen violations add the remote host and port to be able to more easily ascertain the source of the request. Add the same logging for PermitListen violations which were not previously logged at all. - scp(1), sftp(1): Use the correct POSIX format style for left justification for the transfer progress meter. - sshd(8): When examining a configuration using sshd -T, assume any attribute not provided by -C does not match, which allows it to work when sshd_config contains a Match directive with or without -C. - ssh(1), ssh-keygen(1): Downgrade PKCS#11 "provider returned no slots" warning from log level error to debug. This is common when attempting to enumerate keys on smartcard readers with no cards plugged in. - ssh(1), ssh-keygen(1): Do not unconditionally log in to PKCS#11 tokens. Avoids spurious PIN prompts for keys not selected for authentication in ssh(1) and when listing public keys available in a token using ssh-keygen(1). - ssh(1), sshd(8): Fix typo that prevented detection of Linux VRF. - sshd(8): In the Linux seccomp-bpf sandbox, allow mprotect(2) with PROT_(READ|WRITE|NONE) only. This syscall is used by some hardened heap allocators. - sshd(8): In the Linux seccomp-bpf sandbox, allow the s390-specific ioctl for ECC hardware support. * Re-enable hardening on hppa, since the corresponding GCC bug is apparently fixed. -- Colin Watson Thu, 10 Oct 2019 10:23:19 +0100 openssh (1:8.0p1-7) unstable; urgency=medium [ Daniel Kahn Gillmor ] * runit: Correct typo in comment.

This allows the user to paste a fingerprint obtained out of band at the prompt and have the client do the comparison for you. - ssh-keygen(1): When signing multiple certificates on a single command-line invocation, allow automatically incrementing the certificate serial number. - scp(1), sftp(1): Accept -J option as an alias to ProxyJump on the scp and sftp command-lines. - ssh-agent(1), ssh-pkcs11-helper(8), ssh-add(1): Accept "-v" command-line flags to increase the verbosity of output; pass verbose flags though to subprocesses, such as ssh-pkcs11-helper started from ssh-agent. - ssh-add(1): Add a "-T" option to allowing testing whether keys in an agent are usable by performing a signature and a verification. - sftp-server(8): Add a "lsetstat@openssh.com" protocol extension that replicates the functionality of the existing SSH2_FXP_SETSTAT operation but does not follow symlinks. - sftp(1): Add "-h" flag to chown/chgrp/chmod commands to request they do not follow symlinks. - sshd(8): Expose $SSH_CONNECTION in the PAM environment.

Matches in same pass as "Match canonical" but doesn't require hostname canonicalisation be enabled. - sftp(1): Support a prefix of '@' to suppress echo of sftp batch commands. - ssh-keygen(1): When printing certificate contents using "ssh-keygen -Lf /path/certificate", include the algorithm that the CA used to sign the cert. - sshd(8): Fix authentication failures when sshd_config contains "AuthenticationMethods any" inside a Match block that overrides a more restrictive default. - sshd(8): Avoid sending duplicate keepalives when ClientAliveCount is enabled. - sshd(8): Fix two race conditions related to SIGHUP daemon restart. Remnant file descriptors in recently-forked child processes could block the parent sshd's attempt to listen(2) to the configured addresses. Also, the restarting parent sshd could exit before any child processes that were awaiting their re-execution state had completed reading it, leaving them in a fallback path. - ssh(1): Fix stdout potentially being redirected to /dev/null when ProxyCommand=- was in use. - sshd(8): Avoid sending SIGPIPE to child processes if they attempt to write to stderr after their parent processes have exited. - ssh(1): Fix bad interaction between the ssh_config ConnectTimeout and ConnectionAttempts directives - connection attempts after the first were ignoring the requested timeout (LP: #1798049). - ssh-keyscan(1): Return a non-zero exit status if no keys were found (closes: #374980, LP: #1661745). - scp(1): Sanitize scp filenames to allow UTF-8 characters without terminal control sequences. - sshd(8): Fix confusion between ClientAliveInterval and time-based RekeyLimit that could cause connections to be incorrectly closed. - ssh(1), ssh-add(1): Correct some bugs in PKCS#11 token PIN handling at initial token login. The attempt to read the PIN could be skipped in some cases, particularly on devices with integrated PIN readers. This would lead to an inability to retrieve keys from these tokens. - ssh(1), ssh-add(1): Support keys on PKCS#11 tokens that set the CKA_ALWAYS_AUTHENTICATE flag by requring a fresh login after the C_SignInit operation. - ssh(1): Improve documentation for ProxyJump/-J, clarifying that local configuration does not apply to jump hosts. - ssh-keygen(1): Clarify manual - ssh-keygen -e only writes public keys, not private. - ssh(1), sshd(8): be more strict in processing protocol banners, allowing \r characters only immediately before \n. - Various: fix a number of memory leaks. - scp(1), sftp(1): fix calculation of initial bandwidth limits. Account for bytes written before the timer starts and adjust the schedule on which recalculations are performed. Avoids an initial burst of traffic and yields more accurate bandwidth limits. - sshd(8): Only consider the ext-info-c extension during the initial key eschange. It shouldn't be sent in subsequent ones, but if it is present we should ignore it. This prevents sshd from sending a SSH_MSG_EXT_INFO for REKEX for these buggy clients. - ssh-keygen(1): Clarify manual that ssh-keygen -F (find host in authorized_keys) and -R (remove host from authorized_keys) options may accept either a bare hostname or a [hostname]:port combo. - ssh(1): Don't attempt to connect to empty SSH_AUTH_SOCK. - sshd(8): Silence error messages when sshd fails to load some of the default host keys. Failure to load an explicitly-configured hostkey is still an error, and failure to load any host key is still fatal. - ssh(1): Redirect stderr of ProxyCommands to /dev/null when ssh is started with ControlPersist; prevents random ProxyCommand output from interfering with session output. - ssh(1): The ssh client was keeping a redundant ssh-agent socket (leftover from authentication) around for the life of the connection. - sshd(8): Fix bug in HostbasedAcceptedKeyTypes and PubkeyAcceptedKeyTypes options. If only RSA-SHA2 signature types were specified, then authentication would always fail for RSA keys as the monitor checks only the base key (not the signature algorithm) type against *AcceptedKeyTypes. - ssh(1): Request correct signature types from ssh-agent when certificate keys and RSA-SHA2 signatures are in use. - sshd(8): Don't set $MAIL if UsePAM=yes as PAM typically specifies the user environment if it's enabled (closes: #189920, #532754). * Mostly resynced GSSAPI key exchange patch with Fedora. Major changes: - Support selection of GSSAPI key exchange algorithms. - Support GSSAPI key exchange methods with DH and SHA2. - Support GSSAPI key exchange using ECDH and SHA2. - Make sure the Kerberos tickets are cleaned up with the user context. - Enable gssapi-keyex authentication without gssapi-with-mic. - Allow querying for GSSAPI key exchange algorithms from ssh (-Q kex-gss). * Apply upstream patch to fix the utimensat regression tests when not using the compatibility implementation. -- Colin Watson Sun, 09 Jun 2019 22:47:27 +0100 openssh (1:7.9p1-10) unstable; urgency=medium * Temporarily revert IPQoS defaults to pre-7.8 values until issues with "iptables -m tos" and VMware have been fixed (closes: #923879, #926229; LP: #1822370). -- Colin Watson Mon, 08 Apr 2019 11:13:04 +0100 openssh (1:7.9p1-9) unstable; urgency=medium * Apply upstream patch to make scp handle shell-style brace expansions when checking that filenames sent by the server match what the client requested (closes: #923486). -- Colin Watson Fri, 01 Mar 2019 12:23:36 +0000 openssh (1:7.9p1-8) unstable; urgency=medium [ Colin Watson ] * Apply upstream patch to fix bug in HostbasedAcceptedKeyTypes and PubkeyAcceptedKeyTypes options in the case where only RSA-SHA2 signature types were specified. * Apply upstream patch to request RSA-SHA2 signatures for rsa-sha2-{256|512}-cert-v01@openssh.com cert algorithms (closes: #923419). * Move moduli(5) manual page to openssh-server to go with /etc/ssh/moduli; forgotten in 1:7.9p1-5.

This allows autopkgtest to run more efficiently, as it doesn't have to build part of the source tree again. -- Colin Watson Wed, 14 Nov 2018 15:55:48 +0000 openssh (1:7.9p1-1) unstable; urgency=medium * New upstream release (https://www.openssh.com/txt/release-7.9): - ssh(1), sshd(8): allow most port numbers to be specified using service names from getservbyname(3) (typically /etc/services; closes: #177406). - ssh(1): allow the IdentityAgent configuration directive to accept environment variable names. This supports the use of multiple agent sockets without needing to use fixed paths. - sshd(8): support signalling sessions via the SSH protocol. A limited subset of signals is supported and only for login or command sessions (i.e. not subsystems) that were not subject to a forced command via authorized_keys or sshd_config. - ssh(1): support "ssh -Q sig" to list supported signature options. Also "ssh -Q help" to show the full set of supported queries. - ssh(1), sshd(8): add a CASignatureAlgorithms option for the client and server configs to allow control over which signature formats are allowed for CAs to sign certificates. For example, this allows banning CAs that sign certificates using the RSA-SHA1 signature algorithm. - sshd(8), ssh-keygen(1): allow key revocation lists (KRLs) to revoke keys specified by SHA256 hash. - ssh-keygen(1): allow creation of key revocation lists directly from base64-encoded SHA256 fingerprints. This supports revoking keys using only the information contained in sshd(8) authentication log messages. - ssh(1), ssh-keygen(1): avoid spurious "invalid format" errors when attempting to load PEM private keys while using an incorrect passphrase. - sshd(8): when a channel closed message is received from a client, close the stderr file descriptor at the same time stdout is closed. This avoids stuck processes if they were waiting for stderr to close and were insensitive to stdin/out closing (closes: #844494). - ssh(1): allow ForwardX11Timeout=0 to disable the untrusted X11 forwarding timeout and support X11 forwarding indefinitely. Previously the behaviour of ForwardX11Timeout=0 was undefined. - sshd(8): when compiled with GSSAPI support, cache supported method OIDs regardless of whether GSSAPI authentication is enabled in the main section of sshd_config. This avoids sandbox violations if GSSAPI authentication was later enabled in a Match block. - sshd(8): do not fail closed when configured with a text key revocation list that contains a too-short key. - ssh(1): treat connections with ProxyJump specified the same as ones with a ProxyCommand set with regards to hostname canonicalisation (i.e. don't try to canonicalise the hostname unless CanonicalizeHostname is set to 'always'). - ssh(1): fix regression in OpenSSH 7.8 that could prevent public-key authentication using certificates hosted in a ssh-agent(1) or against sshd(8) from OpenSSH <7.8 (LP: #1790963). - All: support building against the openssl-1.1 API (releases 1.1.0g and later). The openssl-1.0 API will remain supported at least until OpenSSL terminates security patch support for that API version (closes: #828475). - sshd(8): allow the futex(2) syscall in the Linux seccomp sandbox; apparently required by some glibc/OpenSSL combinations. * Remove dh_builddeb override to use xz compression; this has been the default since dpkg 1.17.0. * Simplify debian/rules using /usr/share/dpkg/default.mk. * Remove /etc/network/if-up.d/openssh-server, as it causes more problems than it solves (thanks, Christian Ehrhardt, Andreas Hasenack, and David Britton; closes: #789532, LP: #1037738, #1674330, #1718227). Add an "if-up hook removed" section to README.Debian documenting the corner case that may need configuration adjustments. -- Colin Watson Sun, 21 Oct 2018 10:39:24 +0100 openssh (1:7.8p1-1) unstable; urgency=medium * New upstream release (https://www.openssh.com/txt/release-7.8, closes: #907534): - ssh-keygen(1): Write OpenSSH format private keys by default instead of using OpenSSL's PEM format (closes: #905407). The OpenSSH format, supported in OpenSSH releases since 2014 and described in the PROTOCOL.key file in the source distribution, offers substantially better protection against offline password guessing and supports key comments in private keys. If necessary, it is possible to write old PEM-style keys by adding "-m PEM" to ssh-keygen's arguments when generating or updating a key. - sshd(8): Remove internal support for S/Key multiple factor authentication. S/Key may still be used via PAM or BSD auth. - ssh(1): Remove vestigial support for running ssh(1) as setuid. This used to be required for hostbased authentication and the (long gone) rhosts-style authentication, but has not been necessary for a long time. Attempting to execute ssh as a setuid binary, or with uid != effective uid will now yield a fatal error at runtime. - sshd(8): The semantics of PubkeyAcceptedKeyTypes and the similar HostbasedAcceptedKeyTypes options have changed. These now specify signature algorithms that are accepted for their respective authentication mechanism, where previously they specified accepted key types. This distinction matters when using the RSA/SHA2 signature algorithms "rsa-sha2-256", "rsa-sha2-512" and their certificate counterparts. Configurations that override these options but omit these algorithm names may cause unexpected authentication failures (no action is required for configurations that accept the default for these options). - sshd(8): The precedence of session environment variables has changed. ~/.ssh/environment and environment="..." options in authorized_keys files can no longer override SSH_* variables set implicitly by sshd. - ssh(1)/sshd(8): The default IPQoS used by ssh/sshd has changed. They will now use DSCP AF21 for interactive traffic and CS1 for bulk. For a detailed rationale, please see the commit message: https://cvsweb.openbsd.org/src/usr.bin/ssh/readconf.c#rev1.284 - ssh(1)/sshd(8): Add new signature algorithms "rsa-sha2-256-cert- v01@openssh.com" and "rsa-sha2-512-cert-v01@openssh.com" to explicitly force use of RSA/SHA2 signatures in authentication. - sshd(8): Extend the PermitUserEnvironment option to accept a whitelist of environment variable names in addition to global "yes" or "no" settings. - sshd(8): Add a PermitListen directive to sshd_config(5) and a corresponding permitlisten= authorized_keys option that control which listen addresses and port numbers may be used by remote forwarding (ssh -R ...). - sshd(8): Add some countermeasures against timing attacks used for account validation/enumeration. sshd will enforce a minimum time or each failed authentication attempt consisting of a global 5ms minimum plus an additional per-user 0-4ms delay derived from a host secret. - sshd(8): Add a SetEnv directive to allow an administrator to explicitly specify environment variables in sshd_config. Variables set by SetEnv override the default and client-specified environment. - ssh(1): Add a SetEnv directive to request that the server sets an environment variable in the session. Similar to the existing SendEnv option, these variables are set subject to server configuration. - ssh(1): Allow "SendEnv -PATTERN" to clear environment variables previously marked for sending to the server (closes: #573316). - ssh(1)/sshd(8): Make UID available as a %-expansion everywhere that the username is available currently. - ssh(1): Allow setting ProxyJump=none to disable ProxyJump functionality. - sshd(8): Avoid observable differences in request parsing that could be used to determine whether a target user is valid. - ssh(1)/sshd(8): Fix some memory leaks. - ssh(1): Fix a pwent clobber (introduced in openssh-7.7) that could occur during key loading, manifesting as crash on some platforms. - sshd_config(5): Clarify documentation for AuthenticationMethods option. - ssh(1): Ensure that the public key algorithm sent in a public key SSH_MSG_USERAUTH_REQUEST matches the content of the signature blob. Previously, these could be inconsistent when a legacy or non-OpenSSH ssh-agent returned a RSA/SHA1 signature when asked to make a RSA/SHA2 signature. - sshd(8): Fix failures to read authorized_keys caused by faulty supplemental group caching. - scp(1): Apply umask to directories, fixing potential mkdir/chmod race when copying directory trees. - ssh-keygen(1): Return correct exit code when searching for and hashing known_hosts entries in a single operation. - ssh(1): Prefer the ssh binary pointed to via argv[0] to $PATH when re-executing ssh for ProxyJump. - sshd(8): Do not ban PTY allocation when a sshd session is restricted because the user password is expired as it breaks password change dialog. - ssh(1)/sshd(8): Fix error reporting from select() failures. - ssh(1): Improve documentation for -w (tunnel) flag, emphasising that -w implicitly sets Tunnel=point-to-point. - ssh-agent(1): Implement EMFILE mitigation for ssh-agent. ssh-agent will no longer spin when its file descriptor limit is exceeded. - ssh(1)/sshd(8): Disable SSH2_MSG_DEBUG messages for Twisted Conch clients. Twisted Conch versions that lack a version number in their identification strings will mishandle these messages when running on Python 2.x (https://twistedmatrix.com/trac/ticket/9422). - sftp(1): Notify user immediately when underlying ssh process dies expectedly. - ssh(1)/sshd(8): Fix tunnel forwarding; regression in 7.7 release. - ssh-agent(1): Don't kill ssh-agent's listening socket entirely if it fails to accept(2) a connection. - ssh(1): Add some missing options in the configuration dump output (ssh -G). - sshd(8): Expose details of completed authentication to PAM auth modules via SSH_AUTH_INFO_0 in the PAM environment. * Switch debian/watch to HTTPS. * Temporarily work around https://twistedmatrix.com/trac/ticket/9515 in regression tests. -- Colin Watson Thu, 30 Aug 2018 15:35:27 +0100 openssh (1:7.7p1-4) unstable; urgency=high * CVE-2018-15473: Apply upstream patch to delay bailout for invalid authenticating user until after the packet containing the request has been fully parsed (closes: #906236). -- Colin Watson Fri, 17 Aug 2018 14:09:32 +0100 openssh (1:7.7p1-3) unstable; urgency=medium [ Colin Watson ] * Adjust git-dpm tagging configuration. * Remove no-longer-used Lintian overrides from openssh-server and ssh. * Add Documentation keys to ssh-agent.service, ssh.service, and ssh@.service.

These versions were all released in or before 2001 and predate the final SSH RFCs. The support in question isn't necessary for RFC-compliant SSH implementations. - Add experimental support for PQC XMSS keys (Extended Hash-Based Signatures). - sshd(8): Add an "rdomain" criterion for the sshd_config Match keyword to allow conditional configuration that depends on which routing domain a connection was received on. - sshd_config(5): Add an optional rdomain qualifier to the ListenAddress directive to allow listening on different routing domains. - sshd(8): Add "expiry-time" option for authorized_keys files to allow for expiring keys. - ssh(1): Add a BindInterface option to allow binding the outgoing connection to an interface's address (basically a more usable BindAddress; closes: #289592). - ssh(1): Expose device allocated for tun/tap forwarding via a new %T expansion for LocalCommand. This allows LocalCommand to be used to prepare the interface. - sshd(8): Expose the device allocated for tun/tap forwarding via a new SSH_TUNNEL environment variable. This allows automatic setup of the interface and surrounding network configuration automatically on the server. - ssh(1)/scp(1)/sftp(1): Add URI support to ssh, sftp and scp, e.g. ssh://user@host or sftp://user@host/path. Additional connection parameters described in draft-ietf-secsh-scp-sftp-ssh-uri-04 are not implemented since the ssh fingerprint format in the draft uses the deprecated MD5 hash with no way to specify any other algorithm. - ssh-keygen(1): Allow certificate validity intervals that specify only a start or stop time (instead of both or neither). - sftp(1): Allow "cd" and "lcd" commands with no explicit path argument. lcd will change to the local user's home directory as usual. cd will change to the starting directory for session (because the protocol offers no way to obtain the remote user's home directory). - sshd(8): When doing a config test with sshd -T, only require the attributes that are actually used in Match criteria rather than (an incomplete list of) all criteria. - ssh(1)/sshd(8): More strictly check signature types during key exchange against what was negotiated. Prevents downgrade of RSA signatures made with SHA-256/512 to SHA-1. - sshd(8): Fix support for client that advertise a protocol version of "1.99" (indicating that they are prepared to accept both SSHv1 and SSHv2). This was broken in OpenSSH 7.6 during the removal of SSHv1 support. - ssh(1): Warn when the agent returns a ssh-rsa (SHA1) signature when a rsa-sha2-256/512 signature was requested. This condition is possible when an old or non-OpenSSH agent is in use. - ssh-agent(1): Fix regression introduced in 7.6 that caused ssh-agent to fatally exit if presented an invalid signature request message. - sshd_config(5): Accept yes/no flag options case-insensitively, as has been the case in ssh_config(5) for a long time (LP: #1656557). - ssh(1): Improve error reporting for failures during connection. Under some circumstances misleading errors were being shown. - ssh-keyscan(1): Add -D option to allow printing of results directly in SSHFP format. - ssh(1): Compatibility fix for some servers that erroneously drop the connection when the IUTF8 (RFC8160) option is sent. - scp(1): Disable RemoteCommand and RequestTTY in the ssh session started by scp (sftp was already doing this). - ssh-keygen(1): Refuse to create a certificate with an unusable number of principals. - ssh-keygen(1): Fatally exit if ssh-keygen is unable to write all the public key during key generation. Previously it would silently ignore errors writing the comment and terminating newline. - ssh(1): Do not modify hostname arguments that are addresses by automatically forcing them to lower-case. Instead canonicalise them jo resolve ambiguities (e.g. ::0001 => ::1) before they are matched against known_hosts. - ssh(1): Don't accept junk after "yes" or "no" responses to hostkey prompts. - sftp(1): Have sftp print a warning about shell cleanliness when decoding the first packet fails, which is usually caused by shells polluting stdout of non-interactive startups. - ssh(1)/sshd(8): Switch timers in packet code from using wall-clock time to monotonic time, allowing the packet layer to better function over a clock step and avoiding possible integer overflows during steps. - sshd(8): Correctly detect MIPS ABI in use at configure time. Fixes sandbox violations on some environments. - Build and link with "retpoline" flags when available to mitigate the "branch target injection" style (variant 2) of the Spectre branch-prediction vulnerability. -- Colin Watson Tue, 03 Apr 2018 12:40:24 +0100 openssh (1:7.6p1-5) unstable; urgency=medium * Explicitly build-depend on pkg-config, rather than implicitly build-depending on it via libgtk-3-dev (thanks, Aurelien Jarno; closes: #894558). -- Colin Watson Sun, 01 Apr 2018 21:37:19 +0100 openssh (1:7.6p1-4) unstable; urgency=medium * Move VCS to salsa.debian.org. * Add a preseeding-only openssh-server/password-authentication debconf template that can be used to disable password authentication (closes: #878945). -- Colin Watson Sat, 10 Feb 2018 02:31:46 +0000 openssh (1:7.6p1-3) unstable; urgency=medium [ Colin Watson ] * Remove the decade-old ssh-krb5 transitional package; upgrades of openssh-server will preserve existing configuration, and new installations should just enable GSSAPIAuthentication and GSSAPIKeyExchange in sshd_config (closes: #878626). * Support the "noudeb" build profile. * Fix putty-transfer regression test.

Reported by Michal Zalewski. - ssh(1): Delete SSH protocol version 1 support, associated configuration options and documentation (LP: #1584321). - ssh(1)/sshd(8): Remove support for the hmac-ripemd160 MAC. - ssh(1)/sshd(8): Remove support for the arcfour, blowfish and CAST ciphers. - Refuse RSA keys <1024 bits in length and improve reporting for keys that do not meet this requirement. - ssh(1): Do not offer CBC ciphers by default. - ssh(1): Add RemoteCommand option to specify a command in the ssh config file instead of giving it on the client's command line. This allows the configuration file to specify the command that will be executed on the remote host. - sshd(8): Add ExposeAuthInfo option that enables writing details of the authentication methods used (including public keys where applicable) to a file that is exposed via a $SSH_USER_AUTH environment variable in the subsequent session. - ssh(1): Add support for reverse dynamic forwarding. In this mode, ssh will act as a SOCKS4/5 proxy and forward connections to destinations requested by the remote SOCKS client. This mode is requested using extended syntax for the -R and RemoteForward options and, because it is implemented solely at the client, does not require the server be updated to be supported. - sshd(8): Allow LogLevel directive in sshd_config Match blocks. - ssh-keygen(1): Allow inclusion of arbitrary string or flag certificate extensions and critical options. - ssh-keygen(1): Allow ssh-keygen to use a key held in ssh-agent as a CA when signing certificates. - ssh(1)/sshd(8): Allow IPQoS=none in ssh/sshd to not set an explicit ToS/DSCP value and just use the operating system default. - ssh-add(1): Add -q option to make ssh-add quiet on success. - ssh(1): Expand the StrictHostKeyChecking option with two new settings. The first "accept-new" will automatically accept hitherto-unseen keys but will refuse connections for changed or invalid hostkeys. This is a safer subset of the current behaviour of StrictHostKeyChecking=no. The second setting "off", is a synonym for the current behaviour of StrictHostKeyChecking=no: accept new host keys, and continue connection for hosts with incorrect hostkeys. A future release will change the meaning of StrictHostKeyChecking=no to the behaviour of "accept-new". - ssh(1): Add SyslogFacility option to ssh(1) matching the equivalent option in sshd(8). - ssh(1): Use HostKeyAlias if specified instead of hostname for matching host certificate principal names. - sftp(1): Implement sorting for globbed ls. - ssh(1): Add a user@host prefix to client's "Permission denied" messages, useful in particular when using "stacked" connections (e.g. ssh -J) where it's not clear which host is denying. - ssh(1): Accept unknown EXT_INFO extension values that contain \0 characters. These are legal, but would previously cause fatal connection errors if received. - sftp(1): Print '?' instead of incorrect link count (that the protocol doesn't provide) for remote listings. - ssh(1): Return failure rather than fatal() for more cases during session multiplexing negotiations. Causes the session to fall back to a non-mux connection if they occur. - ssh(1): Mention that the server may send debug messages to explain public key authentication problems under some circumstances. - Translate OpenSSL error codes to better report incorrect passphrase errors when loading private keys. - sshd(8): Adjust compatibility patterns for WinSCP to correctly identify versions that implement only the legacy DH group exchange scheme (closes: #877800). - ssh(1): Print the "Killed by signal 1" message only at LogLevel verbose so that it is not shown at the default level; prevents it from appearing during ssh -J and equivalent ProxyCommand configs. - ssh-keygen(1): When generating all hostkeys (ssh-keygen -A), clobber existing keys if they exist but are zero length. Zero-length keys could previously be made if ssh-keygen failed or was interrupted part way through generating them. - ssh-keyscan(1): Avoid double-close() on file descriptors. - sshd(8): Avoid reliance on shared use of pointers shared between monitor and child sshd processes. - sshd_config(8): Document available AuthenticationMethods. - ssh(1): Avoid truncation in some login prompts. - ssh(1): Make "--" before the hostname terminate argument processing after the hostname too (closes: #873201). - ssh-keygen(1): Switch from aes256-cbc to aes256-ctr for encrypting new-style private keys. - ssh(1): Warn and do not attempt to use keys when the public and private halves do not match. - sftp(1): Don't print verbose error message when ssh disconnects from under sftp. - sshd(8): Fix keepalive scheduling problem: prevent activity on a forwarded port from preventing the keepalive from being sent. - sshd(8): When started without root privileges, don't require the privilege separation user or path to exist. - ssh(1)/sshd(8): Correctness fix for channels implementation: accept channel IDs greater than 0x7FFFFFFF. - sshd(8): Expose list of completed authentication methods to PAM via the SSH_AUTH_INFO_0 PAM environment variable. - ssh(1)/sshd(8): Fix several problems in the tun/tap forwarding code, mostly to do with host/network byte order confusion. - sshd(8): Avoid Linux seccomp violations on ppc64le over the socketcall syscall. * Build-depend on debhelper (>= 9.20160709~) rather than dh-systemd. * Change priorities of ssh and ssh-krb5 binary packages to optional, since "Priority: extra" is now deprecated. * Use HTTPS form of copyright-format URL. * Adjust "Running sshd from inittab" instructions in README.Debian to recommend using service(8) rather than calling the init script directly. * Policy version 4.1.0. * Adjust "Per-connection sshd instances with systemd" instructions in README.Debian to recommend using a drop-in file rather than copying and modifying the ssh.socket unit file. -- Colin Watson Fri, 06 Oct 2017 12:36:48 +0100 openssh (1:7.5p1-10) unstable; urgency=medium * Tell haveged to create the pid file we expect. * Give up and use systemctl to start haveged if running under systemd; this shouldn't be necessary, but I can't seem to get things working in the Ubuntu autopkgtest environment otherwise. -- Colin Watson Fri, 01 Sep 2017 11:17:19 +0100 openssh (1:7.5p1-9) unstable; urgency=medium * Run debian/tests/regress with "set -x". * Run haveged without "-w 1024", as setting the low water mark doesn't seem possible in all autopkgtest virtualisation environments. -- Colin Watson Thu, 31 Aug 2017 13:23:04 +0100 openssh (1:7.5p1-8) unstable; urgency=medium * Drop openssh-client-ssh1, now built by a separate source package. * Run haveged during autopkgtests to ensure that they have enough entropy for key generation (LP: #1712921). * Apply patches from https://bugzilla.mindrot.org/show_bug.cgi?id=2752 to allow some extra syscalls for crypto cards on s390x (LP: #1686618). -- Colin Watson Mon, 28 Aug 2017 12:16:35 +0100 openssh (1:7.5p1-7) unstable; urgency=medium * Fix spelling of RuntimeDirectoryMode (closes: #872976). * Add RuntimeDirectory and RuntimeDirectoryMode to ssh@.service as well as ssh.service (closes: #872978). -- Colin Watson Wed, 23 Aug 2017 12:12:59 +0100 openssh (1:7.5p1-6) unstable; urgency=medium [ Colin Watson ] * Test configuration before starting or reloading sshd under systemd (closes: #865770). * Create /run/sshd under systemd using RuntimeDirectory rather than tmpfiles.d (thanks, Dmitry Smirnov; closes: #864190).

Note that the OpenSSH client disables CBC ciphers by default, sshd offers them as lowest-preference options and will remove them by default entirely in the next release. - This release deprecates the sshd_config UsePrivilegeSeparation option, thereby making privilege separation mandatory (closes: #407754). - The format of several log messages emitted by the packet code has changed to include additional information about the user and their authentication state. Software that monitors ssh/sshd logs may need to account for these changes. - ssh(1), sshd(8): Support "=-" syntax to easily remove methods from algorithm lists, e.g. Ciphers=-*cbc. - sshd(1): Fix NULL dereference crash when key exchange start messages are sent out of sequence. - ssh(1), sshd(8): Allow form-feed characters to appear in configuration files. - sshd(8): Fix regression in OpenSSH 7.4 support for the server-sig-algs extension, where SHA2 RSA signature methods were not being correctly advertised. - ssh(1), ssh-keygen(1): Fix a number of case-sensitivity bugs in known_hosts processing. - ssh(1): Allow ssh to use certificates accompanied by a private key file but no corresponding plain *.pub public key. - ssh(1): When updating hostkeys using the UpdateHostKeys option, accept RSA keys if HostkeyAlgorithms contains any RSA keytype. Previously, ssh could ignore RSA keys when only the ssh-rsa-sha2-* methods were enabled in HostkeyAlgorithms and not the old ssh-rsa method. - ssh(1): Detect and report excessively long configuration file lines. - Merge a number of fixes found by Coverity and reported via Redhat and FreeBSD. Includes fixes for some memory and file descriptor leaks in error paths. - ssh(1), sshd(8): When logging long messages to stderr, don't truncate "\r\n" if the length of the message exceeds the buffer. - ssh(1): Fully quote [host]:port in generated ProxyJump/-J command- line; avoid confusion over IPv6 addresses and shells that treat square bracket characters specially. - Fix various fallout and sharp edges caused by removing SSH protocol 1 support from the server, including the server banner string being incorrectly terminated with only \n (instead of \r\n), confusing error messages from ssh-keyscan, and a segfault in sshd if protocol v.1 was enabled for the client and sshd_config contained references to legacy keys. - ssh(1), sshd(8): Free fd_set on connection timeout. - sftp(1): Fix division by zero crash in "df" output when server returns zero total filesystem blocks/inodes. - ssh(1), ssh-add(1), ssh-keygen(1), sshd(8): Translate OpenSSL errors encountered during key loading to more meaningful error codes. - ssh-keygen(1): Sanitise escape sequences in key comments sent to printf but preserve valid UTF-8 when the locale supports it. - ssh(1), sshd(8): Return reason for port forwarding failures where feasible rather than always "administratively prohibited". - sshd(8): Fix deadlock when AuthorizedKeysCommand or AuthorizedPrincipalsCommand produces a lot of output and a key is matched early. - ssh(1): Fix typo in ~C error message for bad port forward cancellation. - ssh(1): Show a useful error message when included config files can't be opened. - sshd_config(5): Repair accidentally-deleted mention of %k token in AuthorizedKeysCommand. - sshd(8): Remove vestiges of previously removed LOGIN_PROGRAM. - ssh-agent(1): Relax PKCS#11 whitelist to include libexec and common 32-bit compatibility library directories. - sftp-client(1): Fix non-exploitable integer overflow in SSH2_FXP_NAME response handling. - ssh-agent(1): Fix regression in 7.4 of deleting PKCS#11-hosted keys.

As 3des-cbc was the only mandatory cipher in the SSH RFCs, this may cause problems connecting to older devices using the default configuration, but it's highly likely that such devices already need explicit configuration for key exchange and hostkey algorithms already anyway. - sshd(8): When a forced-command appears in both a certificate and an authorized keys/principals command= restriction, sshd will now refuse to accept the certificate unless they are identical. The previous (documented) behaviour of having the certificate forced-command override the other could be a bit confusing and error-prone. - sshd(8): Remove the UseLogin configuration directive and support for having /bin/login manage login sessions. - CVE-2016-10009: ssh-agent(1): Will now refuse to load PKCS#11 modules from paths outside a trusted whitelist (run-time configurable). Requests to load modules could be passed via agent forwarding and an attacker could attempt to load a hostile PKCS#11 module across the forwarded agent channel: PKCS#11 modules are shared libraries, so this would result in code execution on the system running the ssh-agent if the attacker has control of the forwarded agent-socket (on the host running the sshd server) and the ability to write to the filesystem of the host running ssh-agent (usually the host running the ssh client) (closes: #848714). - CVE-2016-10010: sshd(8): When privilege separation is disabled, forwarded Unix-domain sockets would be created by sshd(8) with the privileges of 'root' instead of the authenticated user. This release refuses Unix-domain socket forwarding when privilege separation is disabled (Privilege separation has been enabled by default for 14 years) (closes: #848715). - CVE-2016-10011: sshd(8): Avoid theoretical leak of host private key material to privilege-separated child processes via realloc() when reading keys. No such leak was observed in practice for normal-sized keys, nor does a leak to the child processes directly expose key material to unprivileged users (closes: #848716). - CVE-2016-10012: sshd(8): The shared memory manager used by pre-authentication compression support had a bounds checks that could be elided by some optimising compilers. Additionally, this memory manager was incorrectly accessible when pre-authentication compression was disabled. This could potentially allow attacks against the privileged monitor process from the sandboxed privilege-separation process (a compromise of the latter would be required first). This release removes support for pre-authentication compression from sshd(8) (closes: #848717). - SECURITY: sshd(8): Validate address ranges for AllowUser and DenyUsers directives at configuration load time and refuse to accept invalid ones. It was previously possible to specify invalid CIDR address ranges (e.g. user@127.1.2.3/55) and these would always match, possibly resulting in granting access where it was not intended. - ssh(1): Add a proxy multiplexing mode to ssh(1) inspired by the version in PuTTY by Simon Tatham. This allows a multiplexing client to communicate with the master process using a subset of the SSH packet and channels protocol over a Unix-domain socket, with the main process acting as a proxy that translates channel IDs, etc. This allows multiplexing mode to run on systems that lack file-descriptor passing (used by current multiplexing code) and potentially, in conjunction with Unix-domain socket forwarding, with the client and multiplexing master process on different machines. Multiplexing proxy mode may be invoked using "ssh -O proxy ...". - sshd(8): Add a sshd_config DisableForwarding option that disables X11, agent, TCP, tunnel and Unix domain socket forwarding, as well as anything else we might implement in the future. Like the 'restrict' authorized_keys flag, this is intended to be a simple and future-proof way of restricting an account. - sshd(8), ssh(1): Support the "curve25519-sha256" key exchange method. This is identical to the currently-supported method named "curve25519-sha256@libssh.org". - sshd(8): Improve handling of SIGHUP by checking to see if sshd is already daemonised at startup and skipping the call to daemon(3) if it is. This ensures that a SIGHUP restart of sshd(8) will retain the same process-ID as the initial execution. sshd(8) will also now unlink the PidFile prior to SIGHUP restart and re-create it after a successful restart, rather than leaving a stale file in the case of a configuration error. - sshd(8): Allow ClientAliveInterval and ClientAliveCountMax directives to appear in sshd_config Match blocks. - sshd(8): Add %-escapes to AuthorizedPrincipalsCommand to match those supported by AuthorizedKeysCommand (key, key type, fingerprint, etc.) and a few more to provide access to the contents of the certificate being offered. - ssh(1): Allow IdentityFile to successfully load and use certificates that have no corresponding bare public key. - ssh(1): Fix public key authentication when multiple authentication is in use and publickey is not just the first method attempted. - ssh(1): Improve reporting when attempting to load keys from PKCS#11 tokens with fewer useless log messages and more detail in debug messages. - ssh(1): When tearing down ControlMaster connections, don't pollute stderr when LogLevel=quiet. - sftp(1): On ^Z wait for underlying ssh(1) to suspend before suspending sftp(1) to ensure that ssh(1) restores the terminal mode correctly if suspended during a password prompt. - ssh(1): Avoid busy-wait when ssh(1) is suspended during a password prompt (LP: #1646813). - ssh(1), sshd(8): Correctly report errors during sending of ext-info messages. - sshd(8): Fix NULL-deref crash if sshd(8) received an out-of-sequence NEWKEYS message. - sshd(8): Correct list of supported signature algorithms sent in the server-sig-algs extension. - sshd(8): Fix sending ext_info message if privsep is disabled. - sshd(8): More strictly enforce the expected ordering of privilege separation monitor calls used for authentication and allow them only when their respective authentication methods are enabled in the configuration. - sshd_config(5): Use 2001:db8::/32, the official IPv6 subnet for configuration examples. - On environments configured with Turkish locales, fall back to the C/POSIX locale to avoid errors in configuration parsing caused by that locale's unique handling of the letters 'i' and 'I' (LP: #1638338). - contrib: Add a gnome-ssh-askpass3 with GTK+3 support. - sshd(8): Improve PRNG reseeding across privilege separation and force libcrypto to obtain a high-quality seed before chroot or sandboxing. * Apply "wrap-and-sort -at -f debian/control -f debian/tests/control". * Remove entries related to protocol 1 from the default sshd_config generated on new installations. * Remove some advice related to protocol 1 from README.Debian. * Start handling /etc/ssh/sshd_config using ucf. The immediate motivation for this is to deal with deprecations of options related to protocol 1, but something like this has been needed for a long time (closes: #419574, #848089): - sshd_config is now a slightly-patched version of upstream's, and only contains non-default settings (closes: #147201). - I've included as many historical md5sums of default versions of sshd_config as I could reconstruct from version control, but I'm sure I've missed some. - Explicitly synchronise the debconf database with the current configuration file state in openssh-server.config, to ensure that the PermitRootLogin setting is properly preserved. - UsePrivilegeSeparation now defaults to the stronger "sandbox" rather than "yes", per upstream. * Remove redundant "GSSAPIDelegateCredentials no" from ssh_config (already the upstream default), and document that setting ServerAliveInterval to 300 by default if BatchMode is set is Debian-specific (closes: #765630). * Build gnome-ssh-askpass with GTK+ 3 (LP: #801187). * When running regression tests under autopkgtest, use a non-root user with passwordless sudo. -- Colin Watson Tue, 27 Dec 2016 18:01:46 +0000 openssh (1:7.3p1-5) unstable; urgency=medium * debian/tests/control: Add dependency on openssl, required by the PuTTY interoperability tests. -- Colin Watson Sat, 03 Dec 2016 03:43:21 +0000 openssh (1:7.3p1-4) unstable; urgency=medium * Adjust Build-Depends further to avoid considering libssl-dev >= 1.1.0~ as sufficient. * Move build directories under debian/. * Remove the non-upstream .gitignore file and add the relevant entries to debian/.gitignore, in order to make the source tree more dgit-compatible. * Build all upstream regression test binaries using the new "regress-binaries" target. * Fix and enable PuTTY interoperability tests under autopkgtest. -- Colin Watson Fri, 02 Dec 2016 20:49:30 +0000 openssh (1:7.3p1-3) unstable; urgency=medium * Avoid building with OpenSSL 1.1 for now (see #828475). * Add a missing License line to debian/copyright. * Policy version 3.9.8: no changes required. -- Colin Watson Sat, 05 Nov 2016 15:37:15 +0000 openssh (1:7.3p1-2) unstable; urgency=high * Rewrite debian/copyright using copyright-format 1.0. * CVE-2016-8858: Unregister the KEXINIT handler after message has been received (closes: #841884). -- Colin Watson Mon, 24 Oct 2016 11:18:00 +0100 openssh (1:7.3p1-1) unstable; urgency=medium * New upstream release (http://www.openssh.com/txt/release-7.3): - SECURITY: sshd(8): Mitigate a potential denial-of-service attack against the system's crypt(3) function via sshd(8).

These algorithms are already disabled by default in sshd. - ssh(1), sshd(8): Remove unfinished and unused roaming code (was already forcibly disabled in OpenSSH 7.1p2). - ssh(1): Eliminate fallback from untrusted X11 forwarding to trusted forwarding when the X server disables the SECURITY extension. - ssh(1), sshd(8): Increase the minimum modulus size supported for diffie-hellman-group-exchange to 2048 bits. - sshd(8): Pre-auth sandboxing is now enabled by default (previous releases enabled it for new installations via sshd_config). - all: Add support for RSA signatures using SHA-256/512 hash algorithms based on draft-rsa-dsa-sha2-256-03.txt and draft-ssh-ext-info-04.txt. - ssh(1): Add an AddKeysToAgent client option which can be set to 'yes', 'no', 'ask', or 'confirm', and defaults to 'no'. When enabled, a private key that is used during authentication will be added to ssh-agent if it is running (with confirmation enabled if set to 'confirm'). - sshd(8): Add a new authorized_keys option "restrict" that includes all current and future key restrictions (no-*-forwarding, etc.). Also add permissive versions of the existing restrictions, e.g. "no-pty" -> "pty". This simplifies the task of setting up restricted keys and ensures they are maximally-restricted, regardless of any permissions we might implement in the future. - ssh(1): Add ssh_config CertificateFile option to explicitly list certificates. - ssh-keygen(1): Allow ssh-keygen to change the key comment for all supported formats (closes: #811125). - ssh-keygen(1): Allow fingerprinting from standard input, e.g. "ssh-keygen -lf -" (closes: #509058). - ssh-keygen(1): Allow fingerprinting multiple public keys in a file, e.g. "ssh-keygen -lf ~/.ssh/authorized_keys". - sshd(8): Support "none" as an argument for sshd_config Foreground and ChrootDirectory.

It may be re-enabled using the instructions at http://www.openssh.com/legacy.html - Support for ssh-dss, ssh-dss-cert-* host and user keys is disabled by default at run-time. These may be re-enabled using the instructions at http://www.openssh.com/legacy.html - Support for the legacy v00 cert format has been removed. - The default for the sshd_config(5) PermitRootLogin option has changed from "yes" to "prohibit-password". - PermitRootLogin=without-password/prohibit-password now bans all interactive authentication methods, allowing only public-key, hostbased and GSSAPI authentication (previously it permitted keyboard-interactive and password-less authentication if those were enabled). - ssh_config(5): Add PubkeyAcceptedKeyTypes option to control which public key types are available for user authentication. - sshd_config(5): Add HostKeyAlgorithms option to control which public key types are offered for host authentications. - ssh(1), sshd(8): Extend Ciphers, MACs, KexAlgorithms, HostKeyAlgorithms, PubkeyAcceptedKeyTypes and HostbasedKeyTypes options to allow appending to the default set of algorithms instead of replacing it. Options may now be prefixed with a '+' to append to the default, e.g. "HostKeyAlgorithms=+ssh-dss". - sshd_config(5): PermitRootLogin now accepts an argument of 'prohibit-password' as a less-ambiguous synonym of 'without- password'. - ssh(1), sshd(8): Add compatability workarounds for Cisco and more PuTTY versions. - Fix some omissions and errors in the PROTOCOL and PROTOCOL.mux documentation relating to Unix domain socket forwarding. - ssh(1): Improve the ssh(1) manual page to include a better description of Unix domain socket forwarding (closes: #779068). - ssh(1), ssh-agent(1): Skip uninitialised PKCS#11 slots, fixing failures to load keys when they are present. - ssh(1), ssh-agent(1): Do not ignore PKCS#11 hosted keys that wth empty CKA_ID. - sshd(8): Clarify documentation for UseDNS option. - Check realpath(3) behaviour matches what sftp-server requires and use a replacement if necessary. * New upstream release (http://www.openssh.com/txt/release-7.1): - sshd(8): OpenSSH 7.0 contained a logic error in PermitRootLogin= prohibit-password/without-password that could, depending on compile-time configuration, permit password authentication to root while preventing other forms of authentication. This problem was reported by Mantas Mikulenas. - ssh(1), sshd(8): Add compatibility workarounds for FuTTY. - ssh(1), sshd(8): Refine compatibility workarounds for WinSCP. - Fix a number of memory faults (double-free, free of uninitialised memory, etc) in ssh(1) and ssh-keygen(1).

Configurations that match against the client host name (via sshd_config or authorized_keys) may need to re-enable it or convert to matching against addresses. - Add FingerprintHash option to ssh(1) and sshd(8), and equivalent command-line flags to the other tools to control algorithm used for key fingerprints. The default changes from MD5 to SHA256 and format from hex to base64. Fingerprints now have the hash algorithm prepended. An example of the new format: SHA256:mVPwvezndPv/ARoIadVY98vAC0g+P/5633yTC4d/wXE Please note that visual host keys will also be different. - ssh(1), sshd(8): Experimental host key rotation support. Add a protocol extension for a server to inform a client of all its available host keys after authentication has completed. The client may record the keys in known_hosts, allowing it to upgrade to better host key algorithms and a server to gracefully rotate its keys. The client side of this is controlled by a UpdateHostkeys config option (default off). - ssh(1): Add a ssh_config HostbasedKeyType option to control which host public key types are tried during host-based authentication. - ssh(1), sshd(8): Fix connection-killing host key mismatch errors when sshd offers multiple ECDSA keys of different lengths. - ssh(1): When host name canonicalisation is enabled, try to parse host names as addresses before looking them up for canonicalisation. Fixes bz#2074 and avoids needless DNS lookups in some cases. - ssh(1), ssh-keysign(8): Make ed25519 keys work for host based authentication. - sshd(8): SSH protocol v.1 workaround for the Meyer, et al, Bleichenbacher Side Channel Attack. Fake up a bignum key before RSA decryption. - sshd(8): Remember which public keys have been used for authentication and refuse to accept previously-used keys. This allows AuthenticationMethods=publickey,publickey to require that users authenticate using two _different_ public keys. - sshd(8): add sshd_config HostbasedAcceptedKeyTypes and PubkeyAcceptedKeyTypes options to allow sshd to control what public key types will be accepted (closes: #481133). Currently defaults to all. - sshd(8): Don't count partial authentication success as a failure against MaxAuthTries. - ssh(1): Add RevokedHostKeys option for the client to allow text-file or KRL-based revocation of host keys. - ssh-keygen(1), sshd(8): Permit KRLs that revoke certificates by serial number or key ID without scoping to a particular CA. - ssh(1): Add a "Match canonical" criteria that allows ssh_config Match blocks to trigger only in the second config pass. - ssh(1): Add a -G option to ssh that causes it to parse its configuration and dump the result to stdout, similar to "sshd -T". - ssh(1): Allow Match criteria to be negated. E.g. "Match !host". - ssh-keyscan(1): ssh-keyscan has been made much more robust against servers that hang or violate the SSH protocol (closes: #241119). - ssh(1), ssh-keygen(1): Fix regression bz#2306: Key path names were being lost as comment fields (closes: #787776). - ssh(1): Allow ssh_config Port options set in the second config parse phase to be applied (they were being ignored; closes: #774369). - ssh(1): Tweak config re-parsing with host canonicalisation - make the second pass through the config files always run when host name canonicalisation is enabled (and not whenever the host name changes) - ssh(1): Fix passing of wildcard forward bind addresses when connection multiplexing is in use. - ssh-keygen(1): Fix broken private key conversion from non-OpenSSH formats. - ssh-keygen(1): Fix KRL generation bug when multiple CAs are in use. * New upstream release (http://www.openssh.com/txt/release-6.9): - CVE-2015-5352: ssh(1): When forwarding X11 connections with ForwardX11Trusted=no, connections made after ForwardX11Timeout expired could be permitted and no longer subject to XSECURITY restrictions because of an ineffective timeout check in ssh(1) coupled with "fail open" behaviour in the X11 server when clients attempted connections with expired credentials (closes: #790798). This problem was reported by Jann Horn. - SECURITY: ssh-agent(1): Fix weakness of agent locking (ssh-add -x) to password guessing by implementing an increasing failure delay, storing a salted hash of the password rather than the password itself and using a timing-safe comparison function for verifying unlock attempts. This problem was reported by Ryan Castellucci. - sshd(8): Support admin-specified arguments to AuthorizedKeysCommand (closes: #740494). - sshd(8): Add AuthorizedPrincipalsCommand that allows retrieving authorized principals information from a subprocess rather than a file. - ssh(1), ssh-add(1): Support PKCS#11 devices with external PIN entry devices. - ssh-keygen(1): Support "ssh-keygen -lF hostname" to search known_hosts and print key hashes rather than full keys. - ssh-agent(1): Add -D flag to leave ssh-agent in foreground without enabling debug mode. - ssh(1), sshd(8): Deprecate legacy SSH2_MSG_KEX_DH_GEX_REQUEST_OLD message and do not try to use it against some 3rd-party SSH implementations that use it (older PuTTY, WinSCP). - ssh(1), sshd(8): Cap DH-GEX group size at 4Kbits for Cisco implementations as some would fail when attempting to use group sizes >4K (closes: #740307, LP: #1287222). - ssh(1): Fix out-of-bound read in EscapeChar configuration option parsing. - sshd(8): Fix application of PermitTunnel, LoginGraceTime, AuthenticationMethods and StreamLocalBindMask options in Match blocks. - ssh(1), sshd(8): Improve disconnection message on TCP reset. - ssh(1): Remove failed remote forwards established by multiplexing from the list of active forwards. - sshd(8): Make parsing of authorized_keys "environment=" options independent of PermitUserEnv being enabled. - sshd(8): Fix post-auth crash with permitopen=none (closes: #778807). - ssh(1), ssh-add(1), ssh-keygen(1): Allow new-format private keys to be encrypted with AEAD ciphers. - ssh(1): Allow ListenAddress, Port and AddressFamily configuration options to appear in any order. - sshd(8): Check for and reject missing arguments for VersionAddendum and ForceCommand. - ssh(1), sshd(8): Don't treat unknown certificate extensions as fatal. - ssh-keygen(1): Make stdout and stderr output consistent. - ssh(1): Mention missing DISPLAY environment in debug log when X11 forwarding requested. - sshd(8): Correctly record login when UseLogin is set. - sshd(8): Add some missing options to sshd -T output and fix output of VersionAddendum and HostCertificate. - Document and improve consistency of options that accept a "none" argument: TrustedUserCAKeys, RevokedKeys, AuthorizedPrincipalsFile. - ssh(1): Include remote username in debug output. - sshd(8): Avoid compatibility problem with some versions of Tera Term, which would crash when they received the hostkeys notification message (hostkeys-00@openssh.com). - sshd(8): Mention ssh-keygen -E as useful when comparing legacy MD5 host key fingerprints. - ssh(1): Clarify pseudo-terminal request behaviour and make manual language consistent. - ssh(1): Document that the TERM environment variable is not subject to SendEnv and AcceptEnv; bz#2386 - sshd(8): Format UsePAM setting when using sshd -T (closes: #767648). - moduli(5): Update DH-GEX moduli (closes: #787037). * There are some things I want to fix before upgrading to 7.0p1, though I intend to do that soon. In the meantime, backport some patches, mainly to fix security issues: - SECURITY: sshd(8): OpenSSH 6.8 and 6.9 incorrectly set TTYs to be world-writable. Local attackers may be able to write arbitrary messages to logged-in users, including terminal escape sequences. Reported by Nikolay Edigaryev. - SECURITY: sshd(8): Fixed a privilege separation weakness related to PAM support. Attackers who could successfully compromise the pre-authentication process for remote code execution and who had valid credentials on the host could impersonate other users. Reported by Moritz Jodeit. - SECURITY: sshd(8): Fixed a use-after-free bug related to PAM support that was reachable by attackers who could compromise the pre-authentication process for remote code execution (closes: #795711). Also reported by Moritz Jodeit. - CVE-2015-5600: sshd(8): Fix circumvention of MaxAuthTries using keyboard-interactive authentication (closes: #793616). By specifying a long, repeating keyboard-interactive "devices" string, an attacker could request the same authentication method be tried thousands of times in a single pass. The LoginGraceTime timeout in sshd(8) and any authentication failure delays implemented by the authentication mechanism itself were still applied.

In particular, CBC ciphers and arcfour* are disabled by default. The full set of algorithms remains available if configured explicitly via the Ciphers and MACs sshd_config options. - ssh(1), sshd(8): Add support for Unix domain socket forwarding. A remote TCP port may be forwarded to a local Unix domain socket and vice versa or both ends may be a Unix domain socket (closes: #236718). - ssh(1), ssh-keygen(1): Add support for SSHFP DNS records for ED25519 key types. - sftp(1): Allow resumption of interrupted uploads. - ssh(1): When rekeying, skip file/DNS lookups of the hostkey if it is the same as the one sent during initial key exchange. - sshd(8): Allow explicit ::1 and 127.0.0.1 forwarding bind addresses when GatewayPorts=no; allows client to choose address family. - sshd(8): Add a sshd_config PermitUserRC option to control whether ~/.ssh/rc is executed, mirroring the no-user-rc authorized_keys option. - ssh(1): Add a %C escape sequence for LocalCommand and ControlPath that expands to a unique identifier based on a hash of the tuple of (local host, remote user, hostname, port). Helps avoid exceeding miserly pathname limits for Unix domain sockets in multiplexing control paths. - sshd(8): Make the "Too many authentication failures" message include the user, source address, port and protocol in a format similar to the authentication success / failure messages. - Use CLOCK_BOOTTIME in preference to CLOCK_MONOTONIC when it is available. It considers time spent suspended, thereby ensuring timeouts (e.g. for expiring agent keys) fire correctly (closes: #734553). - Use prctl() to prevent sftp-server from accessing /proc/self/{mem,maps}. * Restore TCP wrappers support, removed upstream in 6.7. It is true that dropping this reduces preauth attack surface in sshd. On the other hand, this support seems to be quite widely used, and abruptly dropping it (from the perspective of users who don't read openssh-unix-dev) could easily cause more serious problems in practice.

The old "ln" behaviour of creating a symlink is available using its "-s" option or through the preexisting "symlink" command. - scp(1): Add a new -3 option to scp: Copies between two remote hosts are transferred through the local host (closes: #508613). - ssh(1): "atomically" create the listening mux socket by binding it on a temporary name and then linking it into position after listen() has succeeded. This allows the mux clients to determine that the server socket is either ready or stale without races (closes: #454784). Stale server sockets are now automatically removed (closes: #523250). - ssh(1): install a SIGCHLD handler to reap expired child process (closes: #594687). - ssh(1)/ssh-agent(1): honour $TMPDIR for client xauth and ssh-agent temporary directories (closes: #357469, although only if you arrange for ssh-agent to actually see $TMPDIR since the setgid bit will cause it to be stripped off). * Update to current GSSAPI patch from http://www.sxw.org.uk/computing/patches/openssh-5.7p1-gsskex-all-20110125.patch: - Add GSSAPIServerIdentity option. * Generate ECDSA host keys on fresh installations. Upgraders who wish to add such host keys should manually add 'HostKey /etc/ssh/ssh_host_ecdsa_key' to /etc/ssh/sshd_config and run 'ssh-keygen -q -f /etc/ssh/ssh_host_ecdsa_key -N "" -t ecdsa'. * Build-depend on libssl-dev (>= 0.9.8g) to ensure sufficient ECC support. * Backport SELinux build fix from CVS. * Rearrange selinux-role.patch so that it links properly given this SELinux build fix. -- Colin Watson Wed, 26 Jan 2011 23:48:02 +0000 openssh (1:5.6p1-3) experimental; urgency=low * Drop override for desktop-file-but-no-dh_desktop-call, which Lintian no longer issues. * Merge 1:5.5p1-6. -- Colin Watson Thu, 30 Dec 2010 11:48:00 +0000 openssh (1:5.6p1-2) experimental; urgency=low * Backport upstream patch to install a SIGCHLD handler to reap expired ssh child processes, preventing lots of zombies when using ControlPersist (closes: #594687). -- Colin Watson Tue, 26 Oct 2010 14:46:40 +0100 openssh (1:5.6p1-1) experimental; urgency=low * New upstream release (http://www.openssh.com/txt/release-5.6): - Added a ControlPersist option to ssh_config(5) that automatically starts a background ssh(1) multiplex master when connecting. This connection can stay alive indefinitely, or can be set to automatically close after a user-specified duration of inactivity (closes: #335697, #350898, #454787, #500573, #550262). - Support AuthorizedKeysFile, AuthorizedPrincipalsFile, HostbasedUsesNameFromPacketOnly, and PermitTunnel in sshd_config(5) Match blocks (closes: #549858). - sftp(1): fix ls in working directories that contain globbing characters in their pathnames (LP: #530714). -- Colin Watson Tue, 24 Aug 2010 00:37:54 +0100 openssh (1:5.5p1-6) unstable; urgency=low * Touch /var/run/sshd/.placeholder in the preinst so that /var/run/sshd, which is intentionally no longer shipped in the openssh-server package due to /var/run often being a temporary directory, is not removed on upgrade (closes: #575582). -- Colin Watson Sun, 26 Dec 2010 18:09:29 +0000 openssh (1:5.5p1-5) unstable; urgency=low * Use an architecture wildcard for libselinux1-dev (closes: #591740). * debconf template translations: - Update Danish (thanks, Joe Hansen; closes: #592800). -- Colin Watson Mon, 23 Aug 2010 22:59:03 +0100 openssh (1:5.5p1-4) unstable; urgency=low [ Sebastian Andrzej Siewior ] * Add powerpcspe to architecture list for libselinux1-dev build-dependency (closes: #579843). [ Colin Watson ] * Allow ~/.ssh/authorized_keys and other secure files to be group-writable, provided that the group in question contains only the file's owner; this extends a patch previously applied to ~/.ssh/config (closes: #581919). * Check primary group memberships as well as supplementary group memberships, and only allow group-writability by groups with exactly one member, as zero-member groups are typically used by setgid binaries rather than being user-private groups (closes: #581697). -- Colin Watson Sat, 22 May 2010 23:37:20 +0100 openssh (1:5.5p1-3) unstable; urgency=low * Discard error messages while checking whether rsh, rlogin, and rcp alternatives exist (closes: #579285). * Drop IDEA key check; I don't think it works properly any more due to textual changes in error output, it's only relevant for direct upgrades from truly ancient versions, and it breaks upgrades if /etc/ssh/ssh_host_key can't be loaded (closes: #579570). -- Colin Watson Wed, 28 Apr 2010 22:12:47 +0100 openssh (1:5.5p1-2) unstable; urgency=low * Use dh_installinit -n, since our maintainer scripts already handle this more carefully (thanks, Julien Cristau). -- Colin Watson Sat, 17 Apr 2010 12:55:56 +0100 openssh (1:5.5p1-1) unstable; urgency=low * New upstream release: - Unbreak sshd_config's AuthorizedKeysFile option for $HOME-relative paths. - Include a language tag when sending a protocol 2 disconnection message. - Make logging of certificates used for user authentication more clear and consistent between CAs specified using TrustedUserCAKeys and authorized_keys. -- Colin Watson Fri, 16 Apr 2010 10:27:30 +0100 openssh (1:5.4p1-2) unstable; urgency=low * Borrow patch from Fedora to add DNSSEC support: if glibc 2.11 is installed, the host key is published in an SSHFP RR secured with DNSSEC, and VerifyHostKeyDNS=yes, then ssh will no longer prompt for host key verification (closes: #572049). * Convert to dh(1), and use dh_installdocs --link-doc. * Drop lpia support, since Ubuntu no longer supports this architecture. * Use dh_install more effectively. * Add a NEWS.Debian entry about changes in smartcard support relative to previous unofficial builds (closes: #231472). -- Colin Watson Sat, 10 Apr 2010 01:08:59 +0100 openssh (1:5.4p1-1) unstable; urgency=low * New upstream release (LP: #535029). - After a transition period of about 10 years, this release disables SSH protocol 1 by default. Clients and servers that need to use the legacy protocol must explicitly enable it in ssh_config / sshd_config or on the command-line. - Remove the libsectok/OpenSC-based smartcard code and add support for PKCS#11 tokens. This support is enabled by default in the Debian packaging, since it now doesn't involve additional library dependencies (closes: #231472, LP: #16918). - Add support for certificate authentication of users and hosts using a new, minimal OpenSSH certificate format (closes: #482806). - Added a 'netcat mode' to ssh(1): "ssh -W host:port ...". - Add the ability to revoke keys in sshd(8) and ssh(1). (For the Debian package, this overlaps with the key blacklisting facility added in openssh 1:4.7p1-9, but with different file formats and slightly different scopes; for the moment, I've roughly merged the two.) - Various multiplexing improvements, including support for requesting port-forwardings via the multiplex protocol (closes: #360151). - Allow setting an explicit umask on the sftp-server(8) commandline to override whatever default the user has (closes: #496843). - Many sftp client improvements, including tab-completion, more options, and recursive transfer support for get/put (LP: #33378). The old mget/mput commands never worked properly and have been removed (closes: #270399, #428082). - Do not prompt for a passphrase if we fail to open a keyfile, and log the reason why the open failed to debug (closes: #431538). - Prevent sftp from crashing when given a "-" without a command. Also, allow whitespace to follow a "-" (closes: #531561). * Fix 'debian/rules quilt-setup' to avoid writing .orig files if some patches apply with offsets. * Include debian/ssh-askpass-gnome.png in the Debian tarball now that we're using a source format that permits this, rather than messing around with uudecode. * Drop compatibility with the old gssapi mechanism used in ssh-krb5 << 3.8.1p1-1. Simon Wilkinson refused this patch since the old gssapi mechanism was removed due to a serious security hole, and since these versions of ssh-krb5 are no longer security-supported by Debian I don't think there's any point keeping client compatibility for them. * Fix substitution of ETC_PAM_D_SSH, following the rename in 1:4.7p1-4. * Hardcode the location of xauth to /usr/bin/xauth rather than /usr/bin/X11/xauth (thanks, Aron Griffis; closes: #575725, LP: #8440). xauth no longer depends on x11-common, so we're no longer guaranteed to have the /usr/bin/X11 symlink available. I was taking advantage of the /usr/bin/X11 symlink to smooth X's move to /usr/bin, but this is far enough in the past now that it's probably safe to just use /usr/bin. * Remove SSHD_OOM_ADJUST configuration. sshd now unconditionally makes itself non-OOM-killable, and doesn't require configuration to avoid log spam in virtualisation containers (closes: #555625). * Drop Debian-specific removal of OpenSSL version check. Upstream ignores the two patchlevel nybbles now, which is sufficient to address the original reason this change was introduced, and it appears that any change in the major/minor/fix nybbles would involve a new libssl package name. (We'd still lose if the status nybble were ever changed, but that would mean somebody had packaged a development/beta version rather than a proper release, which doesn't appear to be normal practice.) * Drop most of our "LogLevel SILENT" (-qq) patch. This was originally introduced to match the behaviour of non-free SSH, in which -q does not suppress fatal errors, but matching the behaviour of OpenSSH upstream is much more important nowadays. We no longer document that -q does not suppress fatal errors (closes: #280609). Migrate "LogLevel SILENT" to "LogLevel QUIET" in sshd_config on upgrade. * Policy version 3.8.4: - Add a Homepage field. -- Colin Watson Tue, 06 Apr 2010 22:38:31 +0100 openssh (1:5.3p1-3) unstable; urgency=low * Convert to source format 3.0 (quilt). * Update README.source to match, and add a 'quilt-setup' target to debian/rules for the benefit of those checking out the package from revision control. * All patches are now maintained separately and tagged according to DEP-3. * Add GSSAPIStoreCredentialsOnRekey to 'sshd -T' configuration dump. * Remove documentation of building for Debian 3.0 in README.Debian. Support for this was removed in 1:4.7p1-2. * Remove obsolete header from README.Debian dating from when people expected non-free SSH. * Update copyright years for GSSAPI patch. -- Colin Watson Sun, 28 Feb 2010 01:35:53 +0000 openssh (1:5.3p1-2) unstable; urgency=low * Link with -Wl,--as-needed (closes: #560155). * Install upstream sshd_config as an example (closes: #415008). * Use dh_lintian. * Honour DEB_BUILD_OPTIONS=nocheck. -- Colin Watson Mon, 22 Feb 2010 12:43:24 +0000 openssh (1:5.3p1-1) unstable; urgency=low * New upstream release. * Update to GSSAPI patch from http://www.sxw.org.uk/computing/patches/openssh-5.3p1-gsskex-all-20100124.patch. * Backport from upstream: - Do not fall back to adding keys without constraints (ssh-add -c / -t ...) when the agent refuses the constrained add request. This was a useful migration measure back in 2002 when constraints were new, but just adds risk now (LP: #209447). * Drop change from 1:3.8p1-3 to avoid setresuid() and setresgid() system calls. This only applied to Linux 2.2, which it's no longer feasible to run anyway (see 1:5.2p1-2 changelog). -- Colin Watson Tue, 26 Jan 2010 11:55:29 +0000 openssh (1:5.2p1-2) unstable; urgency=low [ Colin Watson ] * Backport from upstream: - After sshd receives a SIGHUP, ignore subsequent HUPs while sshd re-execs itself. Prevents two HUPs in quick succession from resulting in sshd dying (LP: #497781). - Output a debug if we can't open an existing keyfile (LP: #505301). * Use host compiler for ssh-askpass-gnome when cross-compiling. * Don't run tests when cross-compiling. * Drop change from 1:3.6.1p2-5 to disable cmsg_type check for file descriptor passing when running on Linux 2.0. The previous stable release of Debian dropped support for Linux 2.4, let alone 2.0, so this very likely has no remaining users depending on it. [ Kees Cook ] * Implement DebianBanner server configuration flag that can be set to "no" to allow sshd to run without the Debian-specific extra version in the initial protocol handshake (closes: #562048). -- Colin Watson Sat, 16 Jan 2010 01:28:58 +0000 openssh (1:5.2p1-1) unstable; urgency=low * New upstream release (closes: #536182). Yes, I know 5.3p1 has been out for a while, but there's no GSSAPI patch available for it yet. - Change the default cipher order to prefer the AES CTR modes and the revised "arcfour256" mode to CBC mode ciphers that are susceptible to CPNI-957037 "Plaintext Recovery Attack Against SSH". - Add countermeasures to mitigate CPNI-957037-style attacks against the SSH protocol's use of CBC-mode ciphers. Upon detection of an invalid packet length or Message Authentication Code, ssh/sshd will continue reading up to the maximum supported packet length rather than immediately terminating the connection. This eliminates most of the known differences in behaviour that leaked information about the plaintext of injected data which formed the basis of this attack (closes: #506115, LP: #379329). - ForceCommand directive now accepts commandline arguments for the internal-sftp server (closes: #524423, LP: #362511). - Add AllowAgentForwarding to available Match keywords list (closes: #540623). - Make ssh(1) send the correct channel number for SSH2_MSG_CHANNEL_SUCCESS and SSH2_MSG_CHANNEL_FAILURE messages to avoid triggering 'Non-public channel' error messages on sshd(8) in openssh-5.1. - Avoid printing 'Non-public channel' warnings in sshd(8), since the ssh(1) has sent incorrect channel numbers since ~2004 (this reverts a behaviour introduced in openssh-5.1; closes: #496017). - Disable nonfunctional ssh(1) ~C escape handler in multiplex slave connections (closes: #507541). - Fix "whitepsace" typo in ssh_config(5) (closes: #514313, LP: #303835). * Update to GSSAPI patch from http://www.sxw.org.uk/computing/patches/openssh-5.2p1-gsskex-all-20090726.patch, including cascading credentials support (LP: #416958). * Use x11.pc when compiling/linking gnome-ssh-askpass2 (closes: #555951). * Moved to bzr.debian.org; add Vcs-Bzr and Vcs-Browser control fields. * Add debian/README.source with instructions on bzr handling. * Make ChrootDirectory work with SELinux (thanks, Russell Coker; closes: #556644). * Initialise sc to NULL in ssh_selinux_getctxbyname (thanks, Václav Ovsík; closes: #498684). * Don't duplicate backslashes when displaying server banner (thanks, Michał Górny; closes: #505378, LP: #425346). * Use hardening-includes for hardening logic (thanks, Kees Cook; closes: #561887). * Update OpenSSH FAQ to revision 1.110. * Remove ssh/new_config, only needed for direct upgrades from potato which are no longer particularly feasible anyway (closes: #420682). * Cope with insserv reordering of init script links. * Remove init script stop link in rc1, as killprocs handles it already. * Adjust short descriptions to avoid relying on previous experience with rsh, based on suggestions from Reuben Thomas (closes: #512198). * Remove manual page references to login.conf, which aren't applicable on non-BSD systems (closes: #154434). * Remove/adjust manual page references to BSD-specific /etc/rc (closes: #513417). * Refer to sshd_config(5) rather than sshd(8) in postinst-written /etc/ssh/sshd_config, and add UsePAM commentary from upstream-shipped configuration file (closes: #415008, although unfortunately this will only be conveniently visible on new installations). * Include URL to OpenBSD's ssl(8) in ssh(1), since I don't see a better source for the same information among Debian's manual pages (closes: #530692, LP: #456660). -- Colin Watson Mon, 04 Jan 2010 13:23:35 +0000 openssh (1:5.1p1-8) unstable; urgency=low * Build with just -fPIC on mips/mipsel, not -fPIE as well (thanks, LIU Qi; closes: #538313). * Build-depend on libselinux1-dev on sh4 too (thanks, Nobuhiro Iwamatsu; closes: #547103). * Fix grammar in if-up script (closes: #549128). * Pass $SSHD_OPTS when checking configuration too (thanks, "sobtwmxt"; closes: #548662). -- Colin Watson Mon, 05 Oct 2009 13:30:49 +0100 openssh (1:5.1p1-7) unstable; urgency=low * Update config.guess and config.sub from autotools-dev 20090611.1 (closes: #538301). * Set umask to 022 in the init script as well as postinsts (closes: #539030). * Add ${misc:Depends} to keep Lintian happy. * Use 'which' rather than 'type' in maintainer scripts. * Upgrade to debhelper v7. -- Colin Watson Fri, 31 Jul 2009 16:28:10 +0100 openssh (1:5.1p1-6) unstable; urgency=low * Open /proc/self/oom_adj with O_RDONLY or O_WRONLY as necessary, rather than O_RDWR. * Disable OOM adjustment for vserver/OpenVZ (thanks, Karl Chen; closes: #511771). * Add ufw integration (thanks, Didier Roche; see https://wiki.ubuntu.com/UbuntuFirewall#Integrating%20UFW%20with%20Packages; LP: #261884). * Add a comment above PermitRootLogin in sshd_config pointing to README.Debian. * Check if delgroup is present in openssh-client.postrm (closes: #530501). * Build with -fPIC on mips/mipsel (thanks, Luk Claes; closes: #531942). * Remove /var/run/sshd from openssh-server package; it will be created at run-time before starting the server. * Use invoke-rc.d in openssh-server's if-up script. -- Colin Watson Fri, 05 Jun 2009 11:56:03 +0100 openssh (1:5.1p1-5) unstable; urgency=low * Backport from upstream CVS (Markus Friedl): - packet_disconnect() on padding error, too. Should reduce the success probability for the CPNI-957037 Plaintext Recovery Attack to 2^-18. * Check that /var/run/sshd.pid exists and that the process ID listed there corresponds to sshd before running '/etc/init.d/ssh reload' from if-up script; SIGHUP is racy if called at boot before sshd has a chance to install its signal handler, but fortunately the pid file is written after that which lets us avoid the race (closes: #502444). * While the above is a valuable sanity-check, it turns out that it doesn't really fix the bug (thanks to Kevin Price for testing), so for the meantime we'll just use '/etc/init.d/ssh restart', even though it is unfortunately heavyweight. -- Colin Watson Wed, 14 Jan 2009 00:34:08 +0000 openssh (1:5.1p1-4) unstable; urgency=low * ssh-copy-id: Strip trailing colons from hostname (closes: #226172, LP: #249706; thanks to Karl Goetz for nudging this along; forwarded upstream as https://bugzilla.mindrot.org/show_bug.cgi?id=1530). * Backport from upstream CVS (Markus Friedl): - Only send eow and no-more-sessions requests to openssh 5 and newer; fixes interop problems with broken ssh v2 implementations (closes: #495917). * Fix double-free when failing to parse a forwarding specification given using ~C (closes: #505330; forwarded upstream as https://bugzilla.mindrot.org/show_bug.cgi?id=1539). -- Colin Watson Sun, 23 Nov 2008 14:46:10 +0000 openssh (1:5.1p1-3) unstable; urgency=low * Remove unnecessary ssh-vulnkey output in non-verbose mode when no compromised or unknown keys were found (closes: #496495). * Configure with --disable-strip; dh_strip will deal with stripping binaries and will honour DEB_BUILD_OPTIONS (thanks, Bernhard R.

Important changes not previously backported to 4.7p1: - 4.9/4.9p1 (http://www.openssh.com/txt/release-4.9): + Added chroot(2) support for sshd(8), controlled by a new option "ChrootDirectory" (closes: #139047, LP: #24777). + Linked sftp-server(8) into sshd(8). The internal sftp server is used when the command "internal-sftp" is specified in a Subsystem or ForceCommand declaration. When used with ChrootDirectory, the internal sftp server requires no special configuration of files inside the chroot environment. + Added a protocol extension method "posix-rename@openssh.com" for sftp-server(8) to perform POSIX atomic rename() operations; sftp(1) prefers this if available (closes: #308561). + Removed the fixed limit of 100 file handles in sftp-server(8). + ssh(8) will now skip generation of SSH protocol 1 ephemeral server keys when in inetd mode and protocol 2 connections are negotiated. This speeds up protocol 2 connections to inetd-mode servers that also allow Protocol 1. + Accept the PermitRootLogin directive in a sshd_config(5) Match block. Allows for, e.g. permitting root only from the local network. + Reworked sftp(1) argument splitting and escaping to be more internally consistent (i.e. between sftp commands) and more consistent with sh(1). Please note that this will change the interpretation of some quoted strings, especially those with embedded backslash escape sequences. + Support "Banner=none" in sshd_config(5) to disable sending of a pre-login banner (e.g. in a Match block). + ssh(1) ProxyCommands are now executed with $SHELL rather than /bin/sh. + ssh(1)'s ConnectTimeout option is now applied to both the TCP connection and the SSH banner exchange (previously it just covered the TCP connection). This allows callers of ssh(1) to better detect and deal with stuck servers that accept a TCP connection but don't progress the protocol, and also makes ConnectTimeout useful for connections via a ProxyCommand. + scp(1) incorrectly reported "stalled" on slow copies (closes: #140828). + scp(1) date underflow for timestamps before epoch. + ssh(1) used the obsolete SIG DNS RRtype for host keys in DNS, instead of the current standard RRSIG. + Correctly drain ACKs when a sftp(1) upload write fails midway, avoids a fatal() exit from what should be a recoverable condition. + Fixed ssh-keygen(1) selective host key hashing (i.e. "ssh-keygen -HF hostname") to not include any IP address in the data to be hashed. + Make ssh(1) skip listening on the IPv6 wildcard address when a binding address of 0.0.0.0 is used against an old SSH server that does not support the RFC4254 syntax for wildcard bind addresses. + Enable IPV6_V6ONLY socket option on sshd(8) listen socket, as is already done for X11/TCP forwarding sockets (closes: #439661). + Fix FD leak that could hang a ssh(1) connection multiplexing master. + Make ssh(1) -q option documentation consistent with reality. + Fixed sshd(8) PAM support not calling pam_session_close(), or failing to call it with root privileges (closes: #372680). + Fix activation of OpenSSL engine support when requested in configure (LP: #119295). + Cache SELinux status earlier so we know if it's enabled after a chroot (LP: #237557). - 5.1/5.1p1 (http://www.openssh.com/txt/release-5.1): + Introduce experimental SSH Fingerprint ASCII Visualisation to ssh(1) and ssh-keygen(1). Visual fingerprint display is controlled by a new ssh_config(5) option "VisualHostKey". The intent is to render SSH host keys in a visual form that is amenable to easy recall and rejection of changed host keys. + sshd_config(5) now supports CIDR address/masklen matching in "Match address" blocks, with a fallback to classic wildcard matching. + sshd(8) now supports CIDR matching in ~/.ssh/authorized_keys from="..." restrictions, also with a fallback to classic wildcard matching. + Added an extended test mode (-T) to sshd(8) to request that it write its effective configuration to stdout and exit. Extended test mode also supports the specification of connection parameters (username, source address and hostname) to test the application of sshd_config(5) Match rules. + ssh(1) now prints the number of bytes transferred and the overall connection throughput for SSH protocol 2 sessions when in verbose mode (previously these statistics were displayed for protocol 1 connections only). + sftp-server(8) now supports extension methods statvfs@openssh.com and fstatvfs@openssh.com that implement statvfs(2)-like operations. + sftp(1) now has a "df" command to the sftp client that uses the statvfs@openssh.com to produce a df(1)-like display of filesystem space and inode utilisation (requires statvfs@openssh.com support on the server). + Added a MaxSessions option to sshd_config(5) to allow control of the number of multiplexed sessions supported over a single TCP connection. This allows increasing the number of allowed sessions above the previous default of 10, disabling connection multiplexing (MaxSessions=1) or disallowing login/shell/subsystem sessions entirely (MaxSessions=0). + Added a no-more-sessions@openssh.com global request extension that is sent from ssh(1) to sshd(8) when the client knows that it will never request another session (i.e. when session multiplexing is disabled). This allows a server to disallow further session requests and terminate the session in cases where the client has been hijacked. + ssh-keygen(1) now supports the use of the -l option in combination with -F to search for a host in ~/.ssh/known_hosts and display its fingerprint. + ssh-keyscan(1) now defaults to "rsa" (protocol 2) keys, instead of "rsa1" (LP: #129794). + Added an AllowAgentForwarding option to sshd_config(8) to control whether authentication agent forwarding is permitted. Note that this is a loose control, as a client may install their own unofficial forwarder. + ssh(1) and sshd(8): avoid unnecessary malloc/copy/free when receiving network data, resulting in a ~10% speedup. + ssh(1) and sshd(8) will now try additional addresses when connecting to a port forward destination whose DNS name resolves to more than one address. The previous behaviour was to try the only first address and give up if that failed. + ssh(1) and sshd(8) now support signalling that channels are half-closed for writing, through a channel protocol extension notification "eow@openssh.com". This allows propagation of closed file descriptors, so that commands such as "ssh -2 localhost od /bin/ls | true" do not send unnecessary data over the wire. + sshd(8): increased the default size of ssh protocol 1 ephemeral keys from 768 to 1024 bits. + When ssh(1) has been requested to fork after authentication ("ssh -f") with ExitOnForwardFailure enabled, delay the fork until after replies for any -R forwards have been seen.

This allows some configuration options to be selectively overridden if specific criteria (based on user, group, hostname and/or address) are met. So far a useful subset of post-authentication options are supported and more are expected to be added in future releases. + Add support for Diffie-Hellman group exchange key agreement with a final hash of SHA256. + Added a "ForceCommand" directive to sshd_config(5). Similar to the command="..." option accepted in ~/.ssh/authorized_keys, this forces the execution of the specified command regardless of what the user requested. This is very useful in conjunction with the new "Match" option. + Add a "PermitOpen" directive to sshd_config(5). This mirrors the permitopen="..." authorized_keys option, allowing fine-grained control over the port-forwardings that a user is allowed to establish. + Add optional logging of transactions to sftp-server(8). + ssh(1) will now record port numbers for hosts stored in ~/.ssh/known_hosts when a non-standard port has been requested (closes: #50612). + Add an "ExitOnForwardFailure" option to cause ssh(1) to exit (with a non-zero exit code) when requested port forwardings could not be established. + Extend sshd_config(5) "SubSystem" declarations to allow the specification of command-line arguments. + Replacement of all integer overflow susceptible invocations of malloc(3) and realloc(3) with overflow-checking equivalents. + Many manpage fixes and improvements. + Add optional support for OpenSSL hardware accelerators (engines), enabled using the --with-ssl-engine configure option. + Tokens in configuration files may be double-quoted in order to contain spaces (closes: #319639). + Move a debug() call out of a SIGCHLD handler, fixing a hang when the session exits very quickly (closes: #307890). + Fix some incorrect buffer allocation calculations (closes: #410599). + ssh-add doesn't ask for a passphrase if key file permissions are too liberal (closes: #103677). + Likewise, ssh doesn't ask either (closes: #99675). - 4.6/4.6p1 (http://www.openssh.com/txt/release-4.6): + sshd now allows the enabling and disabling of authentication methods on a per user, group, host and network basis via the Match directive in sshd_config. + Fixed an inconsistent check for a terminal when displaying scp progress meter (closes: #257524). + Fix "hang on exit" when background processes are running at the time of exit on a ttyful/login session (closes: #88337). * Update to current GSSAPI patch from http://www.sxw.org.uk/computing/patches/openssh-4.6p1-gsskex-20070312.patch; install ChangeLog.gssapi. * Build the .deb --with-ssl-engine (closes: #408027, LP: #119295). * Use LSB functions in init scripts, and add an LSB-style header (partly from Ubuntu and partly thanks to Christian Perrier; closes: #389038). * Move init script start links to S16, move rc1 stop link to K84, and remove rc0 and rc6 stop links altogether (the last part from Ubuntu; closes: #122188). * Emit a slightly more informative message from the init script if /dev/null has somehow become not a character device (closes: #369964). * Belatedly build-depend on zlib1g-dev (>= 1:1.2.3-1) (closes: #333447). * Merge from Ubuntu: - Build position-independent executables (only for debs, not for udebs) to take advantage of address space layout randomisation. - If building on Ubuntu, add /sbin, /usr/sbin, and /usr/local/sbin to the default path. * Use ${binary:Version} rather than ${Source-Version} in openssh-server -> openssh-client dependency. -- Colin Watson Wed, 13 Jun 2007 00:28:26 +0100 openssh (1:4.3p2-11) unstable; urgency=low * It's been four and a half years now since I took over as "temporary" maintainer, so the Maintainer field is getting a bit inaccurate.

This code is only built in openssh-krb5, not openssh, but I mention the CVE reference here anyway for completeness. - Add a new compression method ("Compression delayed") that delays zlib compression until after authentication, eliminating the risk of zlib vulnerabilities being exploited by unauthenticated users. Note that users of OpenSSH versions earlier than 3.5 will need to disable compression on the client or set "Compression yes" (losing this security benefit) on the server. - Increase the default size of new RSA/DSA keys generated by ssh-keygen from 1024 to 2048 bits (closes: #181162). - Many bugfixes and improvements to connection multiplexing. - Don't pretend to accept $HOME (closes: #208648). * debian/rules: Resynchronise CFLAGS with that generated by configure. * openssh-client and openssh-server conflict with pre-split ssh to avoid problems when ssh is left un-upgraded (closes: #324695). * Set X11Forwarding to yes in the default sshd_config (new installs only).

Added restorecon calls in preinst and postinst (should not matter if the machine is not SELinux aware). By and large, the changes made should have no effect unless the rules file calls --with-selinux; and even then there should be no performance hit for machines not actively running SELinux. - Modified the preinst and postinst to call restorecon to set the security context for the generated public key files. - Added a comment to /etc/pam.d/ssh to indicate that an SELinux system may want to also include pam_selinux.so. * Re-enable ssh-askpass-gnome on the Hurd, now that its build-dependencies are available. * Restore /usr/lib/sftp-server temporarily, as a symlink to /usr/lib/openssh/sftp-server (closes: #312891). * Switch to debhelper compatibility level 3, since 2 is deprecated. * debconf template translations: - Update German (thanks, Jens Seidel; closes: #313949). -- Colin Watson Fri, 17 Jun 2005 14:20:20 +0100 openssh (1:4.1p1-3) unstable; urgency=low * Upload to unstable. -- Colin Watson Mon, 6 Jun 2005 22:28:33 +0100 openssh (1:4.1p1-2) experimental; urgency=low * Drop debconf support for allowing SSH protocol 1, which is discouraged and has not been the default since openssh 1:3.0.1p1-1.

This is of course a bug in those implementations, but since the extent of the problem is unknown it's best to play safe (closes: #275731). * debconf template translations: - Add Finnish (thanks, Matti Pöllä; closes: #265339). - Update Danish (thanks, Morten Brix Pedersen; closes: #275895). - Update French (thanks, Denis Barbier; closes: #276703). - Update Japanese (thanks, Kenshi Muto; closes: #277438). -- Colin Watson Sun, 24 Oct 2004 17:57:14 +0100 openssh (1:3.8.1p1-8.sarge.1) unstable; urgency=high * If PasswordAuthentication is disabled, then offer to disable ChallengeResponseAuthentication too.

It isn't DFSG-free and only documents the obsolete SSH1 protocol, not to mention that it was never a real RFC but only an Internet-Draft. It's available from http://www.free.lp.se/bamse/draft-ylonen-ssh-protocol-00.txt if you want it for some reason. * Add openssh-client-udeb and openssh-server-udeb binary packages for use in debian-installer. They still need libnss_files to be supplied in udeb form by glibc. * Work around lack of res_query weak alias in libresolv on amd64 (see #242462, awaiting real fix upstream). * Fix grammar in sshd(8) (closes: #238753). * Add .desktop file and icon for ssh-askpass-gnome (closes: #232333). * Update Polish debconf template translation (thanks, Emil Nowak; closes: #242808). * Add Turkish debconf template translation (thanks, Recai Oktaş; closes: #246068). -- Colin Watson Tue, 11 May 2004 23:38:10 +0100 openssh (1:3.8p1-3) unstable; urgency=low * Remove deprecated ReverseMappingCheck option from newly generated sshd_config files (closes: #239987). * Build everything apart from contrib in a subdirectory, to allow for multiple builds. * Some older kernels are missing setresuid() and setresgid(), so don't try to use them. setreuid() and setregid() will do well enough for our purposes (closes: #239999). -- Colin Watson Mon, 5 Apr 2004 21:23:43 +0100 openssh (1:3.8p1-2) unstable; urgency=medium * Disable PasswordAuthentication for new installations (closes: #236810). * Turn off the new ForwardX11Trusted by default, returning to the semantics of 3.7 and earlier, since it seems immature and causes far too many problems with existing setups.

This runs PAM session modules before dropping privileges (closes: #132681, #150968). - Since PAM session modules are run as root, we can turn pam_limits back on by default, and it no longer spits out "Operation not permitted" to syslog (closes: #171673). - Password expiry works again (closes: #153235). - 'ssh -q' suppresses login banner (closes: #134589). - sshd doesn't lie to PAM about invalid usernames (closes: #157078). - ssh-add prints key comment on each prompt (closes: #181869). - Punctuation formatting fixed in man pages (closes: #191131). - EnableSSHKeysign documented in ssh_config(5) (closes: #224457). * Add 'UsePAM yes' to /etc/ssh/sshd_config on upgrade from versions older than this, to maintain the standard Debian sshd configuration. * Comment out PAMAuthenticationViaKbdInt and RhostsAuthentication in sshd_config on upgrade. Neither option is supported any more. * Privilege separation and PAM are now properly supported together, so remove both debconf questions related to them and simply set it unconditionally in newly generated sshd_config files (closes: #228838). * ServerAliveInterval implemented upstream, so ProtocolKeepAlives is now a compatibility alias. The semantics differ slightly, though; see ssh_config(5) for details. * Implement SSH1 support for ServerAliveInterval using SSH_MSG_IGNORE. As documented in ssh_config(5), it's not as good as the SSH2 version. * Remove -fno-builtin-log, -DHAVE_MMAP_ANON_SHARED, and -D__FILE_OFFSET_BITS=64 compiler options, which are no longer necessary. * Update config.guess and config.sub from autotools-dev 20040105.1. * Darren Tucker: - Reset signal status when starting pam auth thread, prevent hanging during PAM keyboard-interactive authentications. - Fix a non-security-critical segfault in PAM authentication. * Add debconf template translations: - Greek (thanks, Konstantinos Margaritis; closes: #232843). - Italian (thanks, Renato Gini; closes: #234777). -- Colin Watson Sat, 6 Mar 2004 18:43:44 +0000 openssh (1:3.6.1p2-12) unstable; urgency=low * Update Spanish debconf template translation (thanks, Javier Fernández-Sanguino Peña; closes: #228242). * Add debconf template translations: - Czech (thanks, Miroslav Kure; closes: #230110). - Simplified Chinese (thanks, Hiei Xu; closes: #230726). -- Colin Watson Wed, 11 Feb 2004 09:37:57 +0000 openssh (1:3.6.1p2-11) unstable; urgency=low * Comment out pam_limits in default configuration, for now at least (closes: #198254). * Use invoke-rc.d (if it exists) to run the init script. * Backport format string bug fix in sshconnect.c (closes: #225238). * ssh-copy-id exits if ssh fails (closes: #215252). -- Colin Watson Sun, 4 Jan 2004 18:59:21 +0000 openssh (1:3.6.1p2-10) unstable; urgency=low * Use --retry in init script when restarting rather than sleeping, to make sure the old process is dead (thanks, Herbert Xu; closes: #212117).

Remove comments about non-functional privilege separation on 2.0 from ssh/privsep_ask and ssh/privsep_tell debconf questions and from README.Debian, since it should all now work. * Fix "defails" typo in generated sshd_config (closes: #206484). * Backport upstream patch to strip trailing whitespace (including newlines) from configuration directives (closes: #192079). -- Colin Watson Wed, 27 Aug 2003 02:19:57 +0100 openssh (1:3.6.1p2-4) unstable; urgency=low * getent can get just one key; no need to use grep (thanks, James Troup). * Move /usr/local/bin to the front of the default path, following /etc/login.defs (closes: #201150). * Remove specifics of problematic countries from package description (closes: #197040). * Update Spanish debconf template translation (thanks, Carlos Valdivia Yagüe; closes: #198456). * Backport upstream patch to pass monitor signals through to child (closes: #164797). -- Colin Watson Sun, 27 Jul 2003 17:31:15 +0100 openssh (1:3.6.1p2-3) unstable; urgency=low * Update French debconf template translation (thanks, Christian Perrier; closes: #194323). * Version the adduser dependency for --no-create-home (closes: #195756). * Add a version of moduli(5), namely revision 1.7 of http://www.openbsd.org/cgi-bin/cvsweb/src/share/man/man5/moduli.5 with '/etc/moduli' changed to '/etc/ssh/moduli' throughout (closes: #196061). -- Colin Watson Mon, 9 Jun 2003 02:51:35 +0100 openssh (1:3.6.1p2-2) unstable; urgency=low * Force /etc/default/ssh to be non-executable, since dpkg apparently doesn't deal with permissions changes on conffiles (closes: #192966). * Use debconf 0.5's seen flag rather than the deprecated isdefault. * Add GPL location to copyright file. * Remove debian/postinst.old. * Switch to po-debconf, with some careful manual use of po2debconf to ensure that the source package continues to build smoothly on woody (closes: #183986). * Update debconf template translations: - Brazilian Portugese (thanks, Andre Luis Lopes; see #183986). - Japanese (thanks, Tomohiro KUBOTA; closes: #192429). * Compile with -fno-builtin-log for now, otherwise gcc-3.3 complains "log.h:59: warning: conflicting types for built-in function `log'". The OpenSSH log() function has been renamed in upstream CVS. -- Colin Watson Mon, 19 May 2003 01:52:38 +0100 openssh (1:3.6.1p2-1) unstable; urgency=medium * New upstream release, including fix for PAM user-discovery security hole (closes: #191681). * Fix ChallengeResponseAuthentication default in generated sshd_config (closes: #106037). * Put newlines after full stops in man page documentation for ProtocolKeepAlives and SetupTimeOut. * Policy version 3.5.9: support DEB_BUILD_OPTIONS=noopt, build gnome-ssh-askpass with -g and -Wall flags. * Really ask ssh/new_config debconf question before trying to fetch its value (closes: #188721). * On purge, remove only the files we know about in /etc/ssh rather than the whole thing, and remove the directory if that leaves it empty (closes: #176679). * ssh has depended on debconf for some time now with no complaints, so: - Simplify the postinst by relying on debconf being present. (The absent case was buggy anyway.) - Get rid of "if you have not installed debconf" text in README.Debian, and generally update the "/usr/bin/ssh not SUID" entry. * More README.Debian work: - Reorganize into "UPGRADE ISSUES" and "OTHER ISSUES", in an effort to make it easier for people to find the former. The upgrade issues should probably be sorted by version somehow. - Document X11UseLocalhost under "X11 Forwarding" (closes: #150913). * Fix setting of IP flags for interactive sessions (upstream bug #541). -- Colin Watson Mon, 5 May 2003 17:47:40 +0100 openssh (1:3.6.1p1-1) unstable; urgency=low * New upstream release (thanks, Laurence J.

Using login.defs would be nice, but that belongs to another package. Without a defined API to retrieve its settings, parsing it is off-limits. * Build ssh-askpass-gnome with GNOME 2. The source package should still support building on stable with GNOME 1, using the alternate libgnome-dev build-dependency (thanks, Colin Walters; closes: #167582). -- Colin Watson Sun, 9 Mar 2003 20:12:10 +0000 openssh (1:3.5p1-4) unstable; urgency=low * Point rlogin and rcp alternatives at slogin and scp respectively rather than ssh (closes: #121103, #151666). Fix alternative removal to match; previously it was completely wrong anyway. * Find out whether /etc/ssh/sshd_not_to_be_run exists and set the debconf question's default using that information, rather than using debconf as a registry. Other solutions may be better in the long run, but this is at least correct (thanks, Matthew Woodcraft; closes: #84725). * Stop using pam_lastlog, as it doesn't currently work well as a session module when privilege separation is enabled; it can usually read /var/log/lastlog but can't write to it. Instead, just use sshd's built-in support, already enabled by default (closes: #151297, #169938). * Use 'ssh-keygen -q' rather than redirecting output to /dev/null. * Add a "this may take some time" warning when creating host keys on installation (part of #110094). * When restarting via the init script, check for sshd_not_to_be_run after stopping sshd (idea from Tomas Pospisek; closes: #149850). * Append /usr/sbin:/sbin to the init script's $PATH, just in case of strangeness (closes: #115138). * Fix a dpkg-statoverride call to redirect stdout to /dev/null, not stderr. * Correct copyright file typo: "orignal" -> "original" (closes: #176490). * Rebuild with libssl0.9.7 (closes: #176983). * We're up to policy version 3.5.6.

(db_text has been a compatibility wrapper since debconf 0.1.5.) * Warn about PermitUserEnvironment on upgrade (closes: #167895). * Use 'make install-nokeys', and disable unused debhelper commands, thereby forward-porting the last pieces of Zack Weinberg's patch (closes: #68341). * Move the man page for gnome-ssh-askpass from the ssh package to ssh-askpass-gnome (closes: #174449). * Build with -DLOGIN_NO_ENDOPT, since Debian's /bin/login doesn't accept '--' to terminate the list of options (closes: #171554). * Add Jonathan Amery's ssh-argv0 script (closes: #111341). * Update Danish debconf template (thanks, Morten Brix Pedersen; closes: #174757). * Document setgid ssh-agent's effect on certain environment variables in README.Debian (closes: #167974). * Document interoperability problems between scp and ssh.com's server in README.Debian, and suggest some workarounds (closes: #174662). -- Colin Watson Wed, 1 Jan 2003 14:18:30 +0000 openssh (1:3.5p1-2) unstable; urgency=low * Mention in the ssh package description that it provides both ssh and sshd (closes: #99680). * Create a system group for ssh-agent, not a user group (closes: #167669). -- Colin Watson Mon, 4 Nov 2002 13:43:53 +0000 openssh (1:3.5p1-1) unstable; urgency=low * New upstream release. - Fixes typo in ssh-add usage (closes: #152239). - Fixes 'PermitRootLogin forced-commands-only' (closes: #166184). - ~/.ssh/environment and environment= options in ~/.ssh/authorized_keys are deprecated for security reasons and will eventually go away. For now they can be re-enabled by setting 'PermitUserEnvironment yes' in sshd_config. - ssh-agent is installed setgid to prevent ptrace() attacks.
