+
+ OpenSSH 8.4 includes a number of changes that may affect existing
+ configurations:
+
+ * ssh-keygen(1): the format of the attestation information optionally
+ recorded when a FIDO key is generated has changed. 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.

+ OpenSSH 8.3 includes a number of changes that may affect existing

+ do instead of accepting and silently ignoring it.

+
+openssh (1:8.2p1-1) unstable; urgency=medium
+
+ OpenSSH 8.2 includes a number of changes that may affect existing
+ configurations:
+
+ * 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.
+
+ Certificates are at special risk to SHA1 collision vulnerabilities as
+ an attacker has effectively unlimited time in which to craft a
+ collision that yields them a valid certificate, far more than the
+ relatively brief LoginGraceTime window that they have to forge a host
+ key signature.
+
+ The OpenSSH certificate format includes a CA-specified (typically
+ random) nonce value near the start of the certificate that should make
+ exploitation of chosen-prefix collisions in this context challenging,
+ as the attacker does not have full control over the prefix that
+ actually gets signed. Nonetheless, SHA1 is now a demonstrably broken
+ algorithm and further improvements in attacks are highly likely.
+
+ OpenSSH releases prior to 7.2 do not support the newer RSA/SHA2
+ algorithms and will refuse to accept certificates signed by an OpenSSH
+ 8.2+ CA using RSA keys unless the unsafe algorithm is explicitly
+ selected during signing ("ssh-keygen -t ssh-rsa"). Older
+ clients/servers may use another CA key type such as ssh-ed25519
+ (supported since OpenSSH 6.5) or one of the ecdsa-sha2-nistp256/384/521
+ types (supported since OpenSSH 5.7) instead if they cannot be upgraded.
+
+ * 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.

+openssh (1:8.1p1-1) unstable; urgency=medium
+
+ OpenSSH 8.1 includes a number of changes that may affect existing
+ configurations:
+
+ * ssh-keygen(1): when acting as a CA and signing certificates with an RSA
+ key, default to using the rsa-sha2-512 signature algorithm.
+ Certificates signed by RSA keys will therefore be incompatible with
+ OpenSSH versions prior to 7.2 unless the default is overridden (using
+ "ssh-keygen -t ssh-rsa -s ...").

+openssh (1:8.0p1-1) experimental; urgency=medium
+
+ OpenSSH 8.0 includes a number of changes that may affect existing
+ configurations:
+
+ * sshd(8): Remove support for obsolete "host/port" syntax.
+ Slash-separated host/port was added in 2001 as an alternative to
+ host:port syntax for the benefit of IPv6 users. These days there are
+ established standards for this like [::1]:22 and the slash syntax is
+ easily mistaken for CIDR notation, which OpenSSH supports for some
+ things. Remove the slash notation from ListenAddress and PermitOpen.

+
+ OpenSSH 7.9 includes a number of changes that may affect existing
+ configurations:
+
+ * ssh(1), sshd(8): the setting of the new CASignatureAlgorithms option
+ bans the use of DSA keys as certificate authorities.
+ * sshd(8): the authentication success/failure log message has changed
+ format slightly. It now includes the certificate fingerprint
+ (previously it included only key ID and CA key fingerprint).

+
+openssh (1:7.8p1-1) unstable; urgency=medium
+
+ OpenSSH 7.8 includes a number of changes that may affect existing
+ configurations:
+
+ * ssh-keygen(1): Write OpenSSH format private keys by default instead of
+ using OpenSSL's PEM format. 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

+ OpenSSH 7.5 includes a number of changes that may affect existing
+ configurations:
+
+ * This release deprecates the sshd_config UsePrivilegeSeparation option,
+ thereby making privilege separation mandatory.
+
+ * 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. For example:
+
+ Connection closed by user x 1.1.1.1 port 1234 [preauth]
+ Connection closed by authenticating user x 10.1.1.1 port 1234 [preauth]
+ Connection closed by invalid user x 1.1.1.1 port 1234 [preauth]
+
+ Affected messages include connection closure, timeout, remote
+ disconnection, negotiation failure and some other fatal messages
+ generated by the packet code.

+
+ This version restores the default for AuthorizedKeysFile to search both
+ ~/.ssh/authorized_keys and ~/.ssh/authorized_keys2, as was the case in
+ Debian configurations before 1:7.4p1-1. Upstream intends to phase out
+ searching ~/.ssh/authorized_keys2 by default, so you should ensure that

+ administrative access; do not assume that the current default will remain
+ in place forever.

+
+openssh (1:7.4p1-1) unstable; urgency=medium
+
+ OpenSSH 7.4 includes a number of changes that may affect existing
+ configurations:
+
+ * ssh(1): Remove 3des-cbc from the client's default proposal. 64-bit
+ block ciphers are not safe in 2016 and we don't want to wait until
+ attacks like SWEET32 are extended to SSH. 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): Remove support for pre-authentication compression. Doing
+ compression early in the protocol probably seemed reasonable in the
+ 1990s, but today it's clearly a bad idea in terms of both cryptography
+ (cf. multiple compression oracle attacks in TLS) and attack surface.
+ Pre-auth compression support has been disabled by default for >10
+ years. Support remains in the client.
+ * ssh-agent will refuse to load PKCS#11 modules outside a whitelist of
+ trusted paths by default. The path whitelist may be specified at
+ run-time.
+ * 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.
+
+ The unprivileged sshd process that deals with pre-authentication network
+ traffic is now subject to additional sandboxing restrictions by default:
+ that is, the default sshd_config now sets UsePrivilegeSeparation to
+ "sandbox" rather than "yes". This has been the case upstream for a while,
+ but until now the Debian configuration diverged unnecessarily.

+
+ OpenSSH 7.0 disables several pieces of weak, legacy, and/or unsafe
+ cryptography.
+
+ * Support for the legacy SSH version 1 protocol is disabled by default at
+ compile time. Note that this also means that the Cipher keyword in
+ ssh_config(5) is effectively no longer usable; use Ciphers instead for
+ protocol 2. The openssh-client-ssh1 package includes "ssh1", "scp1",
+ and "ssh-keygen1" binaries which you can use if you have no alternative
+ way to connect to an outdated SSH1-only server; please contact the
+ server administrator or system vendor in such cases and ask them to
+ upgrade.
+ * Support for the 1024-bit diffie-hellman-group1-sha1 key exchange is
+ disabled by default at run-time. 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.
+
+ Future releases will retire more legacy cryptography, including:
+
+ * Refusing all RSA keys smaller than 1024 bits (the current minimum is
+ 768 bits).
+ * Several ciphers will be disabled by default: blowfish-cbc, cast128-cbc,
+ all arcfour variants, and the rijndael-cbc aliases for AES.
+ * MD5-based HMAC algorithms will be disabled by default.

+
+ The ssh package has been split into openssh-client and openssh-server. If

+ that request will still be honoured. However, the recommended approach is
+ now to remove the openssh-server package if you do not want to run sshd.

+ This version of OpenSSH disables the environment option for public keys by

+OpenSSH for Debian
+------------------
+
+UPGRADE ISSUES
+==============
+
+PermitRootLogin
+---------------
+
+As of 1:6.6p1-1, new installations will be set to "PermitRootLogin
+without-password" (or the synonymous "PermitRootLogin prohibit-password" as
+of 1:7.1p1-1). This disables password authentication for root, foiling
+password dictionary attacks on the root user. Some sites may wish to use
+the stronger "PermitRootLogin forced-commands-only" or "PermitRootLogin no",
+but note that "PermitRootLogin no" will break setups that SSH to root with a
+forced command to take full-system backups. You can use PermitRootLogin in
+a Match block if you want finer-grained control here.
+
+For many years Debian's OpenSSH packaging used "PermitRootLogin yes", in
+line with upstream. To avoid breaking local setups, this is still true for
+installations upgraded from before 1:6.6p1-1. If you wish to change this,
+you should edit /etc/ssh/sshd_config, change it manually, and run "service
+ssh restart" as root.
+
+Disabling PermitRootLogin means that an attacker possessing credentials for
+the root account (any credentials in the case of "yes", or private key
+material in the case of "prohibit-password") must compromise a normal user
+account rather than being able to SSH directly to root. Be careful to avoid
+a false illusion of security if you change this setting; any account you
+escalate to root from should be considered equivalent to root for the
+purposes of security against external attack. You might for example disable
+it if you know you will only ever log in as root from the physical console.
+
+Since the root account does not generally have non-password credentials
+unless you explicitly install an SSH public key in its
+~/.ssh/authorized_keys, which you presumably only do if you want to SSH to
+it, "prohibit-password" should be a reasonable default for most sites.
+
+As of OpenSSH 7.0, this is the upstream default.
+
+For further discussion, see:
+
+ https://bugs.debian.org/298138
+ https://bugzilla.mindrot.org/show_bug.cgi?id=2164
+
+X11 Forwarding
+--------------
+
+ssh's default for ForwardX11 has been changed to ``no'' because it has
+been pointed out that logging into remote systems administered by
+untrusted people is likely to open you up to X11 attacks, so you
+should have to actively decide that you trust the remote machine's
+root, before enabling X11. I strongly recommend that you do this on a
+machine-by-machine basis, rather than just enabling it in the default
+host settings.
+
+In order for X11 forwarding to work, you need to install xauth on the
+server. In Debian this is in the xbase-clients package.
+
+As of OpenSSH 3.1, the remote $DISPLAY uses localhost by default to reduce
+the security risks of X11 forwarding. Look up X11UseLocalhost in
+sshd_config(8) if this is a problem.
+
+OpenSSH 3.8 invented ForwardX11Trusted, which when set to no causes the
+ssh client to create an untrusted X cookie so that attacks on the
+forwarded X11 connection can't become attacks on X clients on the remote
+machine. However, this has some problems in implementation - notably a
+very short timeout of the untrusted cookie - breaks large numbers of
+existing setups, and generally seems immature. The Debian package
+therefore sets the default for this option to "yes" (in ssh itself,
+rather than in ssh_config).
+
+Fallback to RSH
+---------------
+
+The default for this setting has been changed from Yes to No, for
+security reasons, and to stop the delay attempting to rsh to machines
+that don't offer the service. Simply switch it back on in either
+/etc/ssh/ssh_config or ~/.ssh/config for those machines that you need
+it for.
+
+Setgid ssh-agent and environment variables
+------------------------------------------
+
+As of version 1:3.5p1-1, ssh-agent is installed setgid to prevent ptrace()
+attacks retrieving private key material. This has the side-effect of causing
+glibc to remove certain environment variables which might have security
+implications for set-id programs, including LD_PRELOAD, LD_LIBRARY_PATH, and
+TMPDIR.
+
+If you need to set any of these environment variables, you will need to do
+so in the program exec()ed by ssh-agent. This may involve creating a small
+wrapper script.
+
+Symlink Hostname invocation
+---------------------------
+
+This version of ssh no longer includes support for invoking ssh with the
+hostname as the name of the file run. People wanting this support should
+use the ssh-argv0 script.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+OTHER ISSUES
+============
+
+Authorization Forwarding
+------------------------
+
+Similarly, root on a remote server could make use of your ssh-agent
+(while you're logged into their machine) to obtain access to machines
+which trust your keys. This feature is therefore disabled by default.
+You should only re-enable it for those hosts (in your ~/.ssh/config or
+/etc/ssh/ssh_config) where you are confident that the remote machine
+is not a threat.
+
+Problems logging in with RSA authentication
+-------------------------------------------
+
+If you have trouble logging in with RSA authentication then the
+problem is probably caused by the fact that you have your home
+directory writable by group, as well as user (this is the default on
+Debian systems).
+
+Depending upon other settings on your system (i.e. other users being
+in your group) this could open a security hole, so you will need to
+make your home directory writable only by yourself. Run this command,
+as yourself:
+
+ chmod g-w ~/
+
+to remove group write permissions. If you use ssh-copy-id to install your
+keys, it does this for you.
+
+-L option of ssh nonfree
+------------------------
+
+non-free ssh supported the usage of the option -L to use a non privileged
+port for scp. This option will not be supported by scp from openssh.
+
+Please use instead scp -o "UsePrivilegedPort=no" as documented in the
+manpage to scp itself.
+
+Problem logging in because of TCP-Wrappers
+------------------------------------------
+
+ssh is compiled with support for tcp-wrappers. So if you can no longer
+log into your system, please check that /etc/hosts.allow and /etc/hosts.deny
+are configured so that ssh is not blocked.
+
+Kerberos support
+----------------
+
+ssh is now compiled with Kerberos support. Unfortunately, privilege
+separation is incompatible with parts of Kerberos support for protocol 2;
+you may need to run kinit after logging in.
+
+Interoperability between scp and the ssh.com SSH server
+-------------------------------------------------------
+
+In version 2 and greater of the commercial SSH server produced by SSH
+Communications Security, scp was changed to use SFTP (SSH2's file transfer
+protocol) instead of the traditional rcp-over-ssh, thereby breaking
+compatibility. The OpenSSH developers regard this as a bug in the ssh.com
+server, and do not currently intend to change OpenSSH's scp to match.
+
+Workarounds for this problem are to install scp1 on the server (scp2 will
+fall back to it), to use sftp, or to use some other transfer mechanism such
+as rsync-over-ssh or tar-over-ssh.
+
+Running sshd from inittab
+-------------------------
+
+Some people find it useful to run the sshd server from inittab, to make sure
+that it always stays running. To do this, stop sshd ('service ssh stop'),
+add the following line to /etc/inittab, and run 'telinit q':
+
+ ss:2345:respawn:/usr/sbin/sshd -D
+
+If you do this, note that you will need to stop sshd being started in the
+normal way ('update-rc.d ssh disable') and that you will need to restart
+this sshd manually on upgrades.
+
+Per-connection sshd instances with systemd
+------------------------------------------
+
+If you want to reconfigure systemd to listen on port 22 itself and launch an
+instance of sshd for each connection (inetd-style socket activation), then
+you can run:
+
+ systemctl stop ssh.service
+ systemctl start ssh.socket
+
+To make this permanent:
+
+ systemctl disable ssh.service
+ systemctl enable ssh.socket
+
+This may be appropriate in environments where minimal footprint is critical
+(e.g. cloud guests). Be aware that this bypasses MaxStartups, and systemd's
+MaxConnections cannot quite replace this as it cannot distinguish between
+authenticated and unauthenticated connections; see
+https://bugzilla.redhat.com/show_bug.cgi?id=963268 for more discussion.
+
+The provided ssh.socket unit file sets ListenStream=22. If you need to have
+it listen on a different address or port, then you will need to do this as
+follows (modifying ListenStream to match your requirements):
+
+ mkdir -p /etc/systemd/system/ssh.socket.d
+ cat >/etc/systemd/system/ssh.socket.d/listen.conf <<EOF
+ [Socket]
+ ListenStream=2222
+ EOF
+ systemctl daemon-reload
+
+See systemd.socket(5) for details.
+
+Terminating SSH sessions cleanly on shutdown/reboot with systemd
+----------------------------------------------------------------
+
+If you have libpam-systemd >= 230 installed (following openssh-server's
+Recommends) and "UsePAM yes" in sshd_config (the default configuration
+shipped by this package), then SSH sessions will be terminated cleanly when
+the server is shut down or rebooted.
+
+If either of these conditions does not hold, then you may find that SSH
+sessions hang silently when the server is shut down or rebooted. If you do
+not want to use PAM or configure it properly for whatever reason, then you
+can instead copy
+/usr/share/doc/openssh-server/examples/ssh-session-cleanup.service to
+/etc/systemd/system/ and run "systemctl enable ssh-session-cleanup.service".
+
+Non-systemd users may find /usr/lib/openssh/ssh-session-cleanup helpful if
+they have a similar problem, although at present there is no system
+integration for this for anything other than systemd.
+
+SSH protocol 1 server support removed
+-------------------------------------
+
+sshd(8) no longer supports the old SSH protocol 1, so all the configuration
+options related to it are now deprecated and should be removed from
+/etc/ssh/sshd_config. These are:
+
+ KeyRegenerationInterval
+ RSAAuthentication
+ RhostsRSAAuthentication
+ ServerKeyBits
+
+The Protocol option is also no longer needed, although it is silently
+ignored rather than deprecated.
+
+if-up hook removed
+------------------
+
+openssh-server previously shipped an if-up hook that restarted sshd when a
+network interface came up. This generally caused more problems than it
+solved: for instance, it means that sshd stops listening briefly while being
+restarted, which can cause problems in some environments, particularly
+automated tests.
+
+The only known situation where the if-up hook was useful was when
+sshd_config was changed to add ListenAddress entries for particular IP
+addresses, overriding the default of listening on all addresses, and the
+system is one that often roams between networks. In such a situation, it is
+better to remove ListenAddress entries from sshd_config (restoring it to the
+default behaviour) and instead use firewall rules to restrict incoming SSH
+connections to only the desired interfaces or addresses.
+
+For further discussion, see:
+
+ https://bugs.launchpad.net/bugs/1674330
+
+IPQoS defaults reverted to pre-7.8 values
+-----------------------------------------
+
+OpenSSH 7.8 changed the default IPQoS settings to use DSCP AF21 for
+interactive traffic and CS1 for bulk. This caused some problems with other
+software ("iptables -m tos" and VMware), so Debian's OpenSSH reverts this
+change for the time being.
+
+This is *temporary*, and we expect to come back into sync with upstream
+OpenSSH once those other issues have been fixed. If you want to restore the
+upstream default, add this to ssh_config and sshd_config:
+
+ IPQoS af21 cs1

+
+openssh (1:8.4p1-1) unstable; urgency=medium
+
+ * New upstream release (https://www.openssh.com/txt/release-8.4):
+ - [SECURITY] ssh-agent(1): restrict ssh-agent from signing web
+ challenges for FIDO/U2F keys.
+ - [SECURITY] ssh-keygen(1): Enable FIDO 2.1 credProtect extension when
+ generating a FIDO resident key.
+ - ssh-keygen(1): the format of the attestation information optionally
+ recorded when a FIDO key is generated has changed. 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.

+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

+
+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:

+
+openssh (1:8.1p1-1) unstable; urgency=medium
+
+ * New upstream release (https://www.openssh.com/txt/release-8.1):
+ - ssh(1), sshd(8), ssh-agent(1): Add protection for private keys at rest
+ in RAM against speculation and memory side-channel attacks like
+ Spectre, Meltdown and Rambleed. 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 <esc><right> move right to the closest
+ end of a word just like <esc><left> 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.

+ - ssh(1), sshd(8): Add experimental quantum-computing resistant key
+ exchange method, based on a combination of Streamlined NTRU Prime
+ 4591^761 and X25519.
+ - ssh-keygen(1): Increase the default RSA key size to 3072 bits,
+ following NIST Special Publication 800-57's guidance for a 128-bit
+ equivalent symmetric security level (LP: #1445625).
+ - ssh(1): Allow "PKCS11Provider=none" to override later instances of the
+ PKCS11Provider directive in ssh_config.
+ - sshd(8): Add a log message for situations where a connection is
+ dropped for attempting to run a command but a sshd_config
+ ForceCommand=internal-sftp restriction is in effect.
+ - ssh(1): When prompting whether to record a new host key, accept the
+ key fingerprint as a synonym for "yes". 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. This makes
+ the connection 4-tuple available to PAM modules that wish to use it in
+ decision-making.
+ - sshd(8): Add a ssh_config "Match final" predicate. 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.

+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.

+
+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

+
+openssh (1:7.7p1-1) unstable; urgency=medium
+
+ * New upstream release (https://www.openssh.com/txt/release-7.7):
+ - ssh(1)/sshd(8): Drop compatibility support for some very old SSH
+ implementations, including ssh.com <=2.* and OpenSSH <= 3.*. 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.

+ - CVE-2017-15906: sftp-server(8): In read-only mode, sftp-server was
+ incorrectly permitting creation of zero-length files. Reported by
+ Michal Zalewski.
+ - ssh(1): Delete SSH protocol version 1 support, associated

+ - 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

+ - sshd(8): Adjust compatibility patterns for WinSCP to correctly
+ identify versions that implement only the legacy DH group exchange
+ scheme (closes: #877800).

+
+ * New upstream release (https://www.openssh.com/txt/release-7.5):
+ - SECURITY: ssh(1), sshd(8): Fix weakness in CBC padding oracle
+ countermeasures that allowed a variant of the attack fixed in OpenSSH
+ 7.3 to proceed. 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.
+ It was not possible to delete them except by specifying their full
+ physical path.
+ - sshd(8): Avoid sandbox errors for Linux S390 systems using an ICA
+ crypto coprocessor.
+ - sshd(8): Fix non-exploitable weakness in seccomp-bpf sandbox arg
+ inspection.
+ - ssh-keygen(1), ssh(1), sftp(1): Fix output truncation for various that
+ contain non-printable characters where the codeset in use is ASCII.

+
+openssh (1:7.4p1-1) unstable; urgency=medium
+
+ * New upstream release (http://www.openssh.com/txt/release-7.4):
+ - ssh(1): Remove 3des-cbc from the client's default proposal. 64-bit
+ block ciphers are not safe in 2016 and we don't want to wait until
+ attacks like SWEET32 are extended to SSH. 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

+ - SECURITY: ssh(1), sshd(8): Improve operation ordering of MAC
+ verification for Encrypt-then-MAC (EtM) mode transport MAC algorithms
+ to verify the MAC before decrypting any ciphertext. This removes the

+ - sshd(8): Refuse AuthenticationMethods="" in configurations and accept
+ AuthenticationMethods=any for the default behaviour of not requiring

+ - sshd(8): Remove obsolete and misleading "POSSIBLE BREAK-IN ATTEMPT!"
+ message when forward and reverse DNS don't match.
+ - ssh(1): Deduplicate LocalForward and RemoteForward entries to fix

+ - sshd(8): Remove fallback from moduli to obsolete "primes" file that
+ was deprecated in 2001 (LP: #1528251).
+ - sshd_config(5): Correct description of UseDNS: it affects ssh hostname

+
+ * New upstream release (http://www.openssh.com/txt/release-7.2):
+ - This release disables a number of legacy cryptographic algorithms by
+ default in ssh:
+ + Several ciphers blowfish-cbc, cast128-cbc, all arcfour variants and
+ the rijndael-cbc aliases for AES.
+ + MD5-based and truncated HMAC algorithms.
+ 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. Useful inside Match blocks to override a global
+ default.
+ - ssh-keygen(1): Support multiple certificates (one per line) and
+ reading from standard input (using "-f -") for "ssh-keygen -L"
+ - ssh-keyscan(1): Add "ssh-keyscan -c ..." flag to allow fetching
+ certificates instead of plain keys.
+ - ssh(1): Better handle anchored FQDNs (e.g. 'cvs.openbsd.org.') in
+ hostname canonicalisation - treat them as already canonical and remove
+ the trailing '.' before matching ssh_config.
+ - sftp(1): Existing destination directories should not terminate
+ recursive uploads (regression in OpenSSH 6.8; LP: #1553378).
+ * Use HTTPS for Vcs-* URLs, and link to cgit rather than gitweb.
+ * Restore slogin symlinks for compatibility, although they were removed

+ - Support for the legacy SSH version 1 protocol is disabled by default

+ - Support for the 1024-bit diffie-hellman-group1-sha1 key exchange is

+ - 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).

+ 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). Reported by Mateusz
+ Kocielski.

+ - sshd(8): UseDNS now defaults to 'no'. 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

+ - sshd(8): Remember which public keys have been used for authentication
+ and refuse to accept previously-used keys. This allows

+ 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".

+ 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. Found by Kingcope.
+ - Let principals-command.sh work for noexec /var/run.
+ * Thanks to Jakub Jelen of Red Hat for Fedora's rebased version of the
+ GSSAPI key exchange patch.
+ * Document the Debian-specific change to the default value of
+ ForwardX11Trusted in ssh(1) (closes: #781469).

+ * New upstream release (http://www.openssh.com/txt/release-6.7):
+ - sshd(8): The default set of ciphers and MACs has been altered to
+ remove unsafe algorithms. 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. It's not entirely clear
+ what the right long-term answer for Debian is, but it at least probably
+ doesn't involve dropping this feature shortly before a freeze.
+ * Replace patch to disable OpenSSL version check with an updated version
+ of Kurt Roeckx's patch from #732940 to just avoid checking the status
+ field.
+ * Build-depend on a new enough dpkg-dev for dpkg-buildflags, rather than
+ simply a new enough dpkg.
+ * Simplify debian/rules using /usr/share/dpkg/buildflags.mk.
+ * Use Package-Type rather than XC-Package-Type, now that it is an official
+ field.
+ * Run a subset of the upstream regression test suite at package build
+ time, and the rest of it under autopkgtest.

+ 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

+ * 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.

+ * 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.

+ * 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:

+ 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).

+openssh (1:5.1p1-1) unstable; urgency=low
+
+ * New upstream release (closes: #474301). 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. Allows for robust
+ detection of -R forward failure when using -f.
+ + "Match group" blocks in sshd_config(5) now support negation of
+ groups. E.g. "Match group staff,!guests".
+ + sftp(1) and sftp-server(8) now allow chmod-like operations to set
+ set[ug]id/sticky bits.
+ + The MaxAuthTries option is now permitted in sshd_config(5) match
+ blocks.
+ + Multiplexed ssh(1) sessions now support a subset of the ~ escapes
+ that are available to a primary connection.
+ + ssh(1) connection multiplexing will now fall back to creating a new
+ connection in most error cases (closes: #352830).
+ + Make ssh(1) deal more gracefully with channel requests that fail.
+ Previously it would optimistically assume that requests would always
+ succeed, which could cause hangs if they did not (e.g. when the
+ server runs out of file descriptors).
+ + ssh(1) now reports multiplexing errors via the multiplex slave's
+ stderr where possible (subject to LogLevel in the mux master).
+ + Fixed an UMAC alignment problem that manifested on Itanium
+ platforms.
+ * Remove our local version of moduli(5) now that there's one upstream.
+ * Say "GTK+" rather than "GTK" in ssh-askpass-gnome's description.
+ * Add lintian overrides for empty /usr/share/doc/openssh-client

+
+ * New upstream release (closes: #395507, #397961, #420035). Important
+ changes not previously backported to 4.3p2:
+ - 4.4/4.4p1 (http://www.openssh.com/txt/release-4.4):
+ + On portable OpenSSH, fix a GSSAPI authentication abort that could be
+ used to determine the validity of usernames on some platforms.
+ + Implemented conditional configuration in sshd_config(5) using the
+ "Match" directive. 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

+ * New upstream release (closes: #361032).
+ - CVE-2006-0225: scp (as does rcp, on which it is based) invoked a
+ subshell to perform local to local, and remote to remote copy
+ operations. This subshell exposed filenames to shell expansion twice;
+ allowing a local attacker to create filenames containing shell
+ metacharacters that, if matched by a wildcard, could lead to execution
+ of attacker-specified commands with the privilege of the user running
+ scp (closes: #349645).
+ - Add support for tunneling arbitrary network packets over a connection
+ between an OpenSSH client and server via tun(4) virtual network
+ interfaces. This allows the use of OpenSSH (4.3+) to create a true VPN
+ between the client and server providing real network connectivity at
+ layer 2 or 3. This feature is experimental.
+ - Reduce default key length for new DSA keys generated by ssh-keygen
+ back to 1024 bits. DSA is not specified for longer lengths and does
+ not fully benefit from simply making keys longer. As per FIPS 186-2
+ Change Notice 1, ssh-keygen will refuse to generate a new DSA key
+ smaller or larger than 1024 bits.
+ - Fixed X forwarding failing to start when the X11 client is executed in

+ - Change ssh-keygen to generate a protocol 2 RSA key when invoked
+ without arguments (closes: #114894).
+ - Fix timing variance for valid vs. invalid accounts when attempting

+ - Ensure that ssh always returns code 255 on internal error
+ (closes: #259865).
+ - Cleanup wtmp files on SIGTERM when not using privsep.

+ - Ensure that fds 0, 1 and 2 are always attached in all programs, by
+ duping /dev/null to them if necessary.
+ - Xauth list invocation had bogus "." argument.

+ * Split the ssh binary package into openssh-client and openssh-server

+ * New transitional ssh package, priority optional, depending on
+ openssh-client and openssh-server. May be removed once nothing depends
+ on it.
+ * When upgrading from ssh to openssh-{client,server}, it's very difficult
+ for the maintainer scripts to find out what version we're upgrading from
+ without dodgy dpkg hackery. I've therefore taken the opportunity to move
+ a couple of debconf notes into NEWS files, namely ssh/ssh2_keys_merged
+ and ssh/user_environment_tell.
+ * Add a heuristic to try to make sure the sshd_config upgrade to >= 3.7
+ happens even though we don't know what version we're upgrading from.
+ * Remove /etc/ssh/sshd_not_to_be_run on purge of openssh-server. For now
+ (until sarge+2) it's still honoured to avoid breaking existing
+ configurations, but the right approach is now to remove the
+ openssh-server package if you don't want to run the server. Add a NEWS

+ than this, to maintain the standard Debian sshd configuration.
+ * Comment out PAMAuthenticationViaKbdInt and RhostsAuthentication in

+ * 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.

+ - ~/.ssh/environment and environment= options in ~/.ssh/authorized_keys
+ are deprecated for security reasons and will eventually go away. For

+ sshd_config.
+ - ssh-agent is installed setgid to prevent ptrace() attacks. The group
+ actually doesn't matter, as it drops privileges immediately, but to
+ avoid confusion the postinst creates a new 'ssh' group for it.
+ * Obsolete patches:
+ - Solar Designer's privsep+compression patch for Linux 2.2 (see

+ - Hostbased auth ssh-keysign backport (see 1:3.4p1-4).

+ * Source the debconf confmodule at the top of the postrm rather than at

+ group.
+ .
+ Ssh (Secure Shell) is a program for logging into a remote machine
+ and for executing commands on a remote machine.
+ It provides secure encrypted communications between two untrusted
+ hosts over an insecure network. X11 connections and arbitrary TCP/IP
+ ports can also be forwarded over the secure channel.
+ It can be used to provide applications with a secure communication
+ channel.
+ .
+ This package provides the ssh, scp and sftp clients, the ssh-agent
+ and ssh-add programs to make public key authentication more convenient,
+ and the ssh-keygen, ssh-keyscan, ssh-copy-id and ssh-argv0 utilities.
+ .
+ In some countries it may be illegal to use any encryption at all
+ without a special permit.

+
+OpenSSH provides end-to-end encrypted replacement of applications such as
+telnet, rlogin, and ftp.
+Unlike these legacy applications, OpenSSH never passes anything
+(including username and password) over the wire in unencrypted form, and
+provides host authentication, to verify that you really are talking to
+the system that you think you are and that no one else can take over
+that session.
+
+<p>
+The OpenSSH suite includes the
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1">ssh(1)</a>
+program which replaces rlogin and telnet, and
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&amp;sektion=1">scp(1)</a>
+which replaces
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=rcp&amp;sektion=1">rcp(1)</a> and
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ftp&amp;sektion=1">ftp(1)</a>.
+OpenSSH has also added
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&amp;sektion=1">sftp(1)</a> and
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp-server&amp;sektion=8">sftp-server(8)</a>
+which implement an easier solution for file-transfer. This is based upon the
+<a href="http://www.openssh.com/txt/draft-ietf-secsh-filexfer-02.txt">secsh-filexfer</a> IETF draft.
+
+
+<p><strong>OpenSSH consists of a number of programs.</strong>
+
+<ul>
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a> - Server program run on the server machine. This listens for connections from client machines, and whenever it receives a connection, it performs authentication and starts serving the client.
+Its behaviour is controlled by the config file <i><a
+href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&amp;sektion=5">
+sshd_config(5)</a></i>.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1">ssh(1)</a> - This is the client program used to log into another machine or to execute commands on the other machine. <i>slogin</i> is another name for this program.
+Its behaviour is controlled by the global config file <i><a
+href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh_config&amp;sektion=5">
+ssh_config(5)</a></i> and individual users' <i>$HOME/.ssh/config</i> files.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&amp;sektion=1">scp(1)</a> - Securely copies files from one machine to another.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keygen&amp;sektion=1">ssh-keygen(1)</a> - Used to create Pubkey Authentication (RSA or DSA) keys (host keys and user authentication keys).
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-agent&amp;sektion=1">ssh-agent(1)</a> - Authentication agent. This can be used to hold RSA keys for authentication.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-add&amp;sektion=1">ssh-add(1)</a> - Used to register new keys with the agent.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp-server&amp;sektion=8">sftp-server(8)</a> - SFTP server subsystem.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&amp;sektion=1">sftp(1)</a> - Secure file transfer program.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keyscan&amp;sektion=1">ssh-keyscan(1)</a> - gather ssh public keys.
+<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keysign&amp;sektion=8">ssh-keysign(8)</a> - ssh helper program for hostbased authentication.

+
+<h3>Downloading</h3>
+
+<p>
+The most recent version of OpenSSH is included with the current
+distribution of <a href="http://www.openbsd.org/">OpenBSD</a>, and
+installed as part of a basic install.
+
+<p>
+Today, most other operating systems include some version of OpenSSH
+(often re-badged or privately labeled), so most users can immediately
+use it.
+However, sometimes the included versions are quite old, and missing
+features of the current release of OpenSSH, and you may wish to install
+the current version, or install it on one of the few OSs that lacked it,
+and where the OS publisher does not make a modern version available.
+You may also wish to use OpenSSH on your embedded application.
+
+<p>
+Non-OpenBSD users will want to download, compile and install the
+multi-platform <a href="http://www.openssh.com/portable.html">Portable</a> distribution from a
+<a href="http://www.openssh.com/portable.html#mirrors">mirror</a> near you.
+
+
+<h2><a name= "1.2">1.2 - Why should it be used?</a></h2>
+
+<p>
+OpenSSH is a suite of tools to help secure your network
+connections. Here is a list of features:
+
+
+<ul>
+ <li>Strong authentication. Closes several security holes (e.g., IP, routing, and DNS spoofing).
+ <li>Improved privacy. All communications are automatically and transparently encrypted.
+ <li>Secure X11 sessions. The program automatically sets DISPLAY on the server machine, and forwards any X11 connections over the secure channel.
+ <li>Arbitrary TCP/IP ports can be redirected through the encrypted channel in both directions (e.g., for e-cash transactions).
+ <li>No retraining needed for normal users.
+ <li>Never trusts the network. Minimal trust on the remote side of the connection. Minimal trust on domain name servers. Pure RSA authentication never trusts anything but the private key.
+ <li>Client RSA-authenticates the server machine in the beginning of every connection to prevent trojan horses (by routing or DNS spoofing) and man-in-the-middle attacks, and the server RSA-authenticates the client machine before accepting <i>.rhosts</i> or <i>/etc/hosts.equiv</i> authentication (to prevent DNS, routing, or IP-spoofing).
+ <li>Host authentication key distribution can be centrally by the administration, automatically when the first connection is made to a machine.
+ <li>Any user can create any number of user authentication RSA keys for his/her own use.
+ <li>The server program has its own server RSA key which is automatically regenerated every hour.
+ <li>An authentication agent, running in the user's laptop or local workstation, can be used to hold the user's RSA authentication keys.
+ <li>The software can be installed and used (with restricted functionality) even without root privileges.
+ <li>The client is customizable in system-wide and per-user configuration files.
+ <li>Optional compression of all data with gzip (including forwarded X11 and TCP/IP port data), which may result in significant speedups on slow connections.
+ <li>Complete replacement for rlogin, rsh, and rcp.
+</ul>
+
+<p>
+Currently, almost all communications in computer networks are done
+without encryption. As a consequence, anyone who has access to any
+machine connected to the network can listen in on any communication.
+This is being done by hackers, curious administrators, employers,
+criminals, industrial spies, and governments. Some networks leak off
+enough electromagnetic radiation that data may be captured even from a
+distance.
+
+
+<p>
+When you log in, your password goes in the network in plain
+text. Thus, any listener can then use your account to do any evil he
+likes. Many incidents have been encountered worldwide where crackers
+have started programs on workstations without the owner's knowledge
+just to listen to the network and collect passwords. Programs for
+doing this are available on the Internet, or can be built by a
+competent programmer in a few hours.
+
+
+<p>
+Businesses have trade secrets, patent applications in preparation,
+pricing information, subcontractor information, client data, personnel
+data, financial information, etc. Currently, anyone with access to
+the network (any machine on the network) can listen to anything that
+goes in the network, without any regard to normal access restrictions.
+
+
+<p>
+Many companies are not aware that information can so easily be
+recovered from the network. They trust that their data is safe
+since nobody is supposed to know that there is sensitive information
+in the network, or because so much other data is transferred in the
+network. This is not a safe policy.
+
+
+<h2><a name= "1.3">1.3 - What operating systems are supported?</a></h2>
+
+<p>
+Even though OpenSSH is developed on
+<a href="http://www.openbsd.org/">OpenBSD</a> a wide variety of
+ports to other operating systems exist. The portable version of OpenSSH
+is headed by <a href="mailto:djm@openbsd.org">Damien Miller</a>.
+For a quick overview of the portable version of OpenSSH see
+<a href="http://www.openssh.com/portable.html">OpenSSH Portable Release</a>.
+Currently, the supported operating systems are:
+
+
+<ul>
+ <li>OpenBSD
+ <li>NetBSD
+ <li>FreeBSD
+ <li>AIX
+ <li>HP-UX
+ <li>IRIX
+ <li>Linux
+ <li>NeXT
+ <li>SCO

+
+<h2><a name= "1.4">1.4 - What about copyrights, usage and patents?</a></h2>
+<p>
+The OpenSSH developers have tried very hard to keep OpenSSH free of any
+patent or copyright problems. To do this, some options had to be
+stripped from OpenSSH. Namely support for patented algorithms.
+
+<p>
+OpenSSH does not support any patented transport algorithms. In SSH1 mode,
+only 3DES and Blowfish are available options. In SSH2 mode, only 3DES,
+Blowfish, CAST128, Arcfour and AES can be selected.
+The patented IDEA algorithm is not supported.
+
+<p>
+OpenSSH provides support for both SSH1 and SSH2 protocols.
+
+<p>
+Since the RSA patent has expired, there are no restrictions on the use
+of RSA algorithm using software, including OpenBSD.
+
+<h2><a name= "1.5">1.5 - Where should I ask for help?</a></h2>
+<p>
+There are many places to turn to for help. In addition to the main

+
+<h2><u><a name= "2.0">2.0 - General Questions</a></u></h2>
+
+<h2><a name= "2.1">2.1 - Why does ssh/scp make connections from low-numbered ports.</a></h2>
+<p>
+The OpenSSH client uses low numbered ports for rhosts and rhosts-rsa
+authentication because the server needs to trust the username provided by
+the client. To get around this, you can add the below example to your
+<i>ssh_config</i> or <i>~/.ssh/config</i> file.
+
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+<b>UsePrivilegedPort no</b>
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<p>
+Or you can specify this option on the command line, using the <b>-o</b>
+option to
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1">ssh(1)</a> command.
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+$ <b>ssh -o "UsePrivilegedPort no" host.com</b>
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<h2><a name= "2.2">2.2 - Why is the ssh client setuid root?</a></h2>
+
+<p>
+In conjunction with the previous question, (<a href="#2.1">2.1</a>)
+OpenSSH needs root authority to be able to bind to low-numbered ports to
+facilitate <i>rhosts authentication</i>.
+A privileged port is also required for rhosts-rsa authentication to older
+SSH releases.
+
+<p>
+Additionally, for both <i>rhosts-rsa authentication</i> (in protocol
+version 1) and <i>hostbased authentication</i> (in protocol version 2)
+the ssh client needs to access the <i>private host key</i> in order to
+authenticate the client machine to the server.
+OpenSSH versions prior to 3.3 required the <code>ssh</code> binary to be
+setuid root to enable this, and you may safely remove it if you don't
+want to use these authentication methods.
+
+<p>
+Starting in OpenSSH 3.3, <code>ssh</code> is not setuid by default. <a
+href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keysign">ssh-keysign</a>,
+is used for access to the private hosts keys, and ssh does not use privileged
+source ports by default. If you wish to use a privileged source port, you must
+manually set the setuid bit on <code>ssh</code>.
+
+<h2><a name= "2.3">2.3 - Why does SSH 2.3 have problems interoperating with OpenSSH 2.1.1?</a></h2>
+
+<p>
+SSH 2.3 and earlier versions contain a flaw in their HMAC implementation.
+Their code was not supplying the full data block output from the digest,
+and instead always provided 128 bits. For longer digests, this caused
+SSH 2.3 to not interoperate with OpenSSH.
+
+<p>
+OpenSSH 2.2.0 detects that SSH 2.3 has this flaw. Recent versions of SSH
+will have this bug fixed. Or you can add the following to
+SSH 2.3 <i>sshd2_config</i>.
+
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+<b>Mac hmac-md5</b>
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<h2><a name= "2.4">2.4 - Why does OpenSSH print: Dispatch protocol error: type 20</a></h2>
+
+<p>
+Problems in interoperation have been seen because older versions of
+OpenSSH did not support session rekeying. However the commercial SSH 2.3
+tries to negotiate this feature, and you might experience connection
+freezes or see the error message &quot;<b>Dispatch protocol error:
+type 20 </b>&quot;.
+To solve this problem, either upgrade to a recent OpenSSH release or
+disable rekeying by adding the following to your commercial SSH 2.3's
+<i>ssh2_config</i> or <i>sshd2_config</i>.
+
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+<b>RekeyIntervalSeconds 0</b>
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<h2><a name= "2.5">2.5 - Old versions of commercial SSH encrypt host keys with IDEA.</a></h2>
+
+<p>
+The old versions of SSH used a patented algorithm to encrypt their
+<i>/etc/ssh/ssh_host_key</i>. This problem will manifest as
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a>
+not being able to read its host key. To solve this, use the command below
+to convert your ssh_host_key to use 3DES.
+<b>NOTE:</b> Use the
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keygen&amp;sektion=1">ssh-keygen(1)</a>
+program from the Commercial SSH product, *NOT* OpenSSH for the example
+below.
+
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+# <b>ssh-keygen -u -f /etc/ssh/ssh_host_key</b>
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<h2><a name= "2.6">2.6 - What are these warning messages about key lengths</a></h2>
+
+<p>
+Commercial SSH's
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keygen&amp;sektion=1">ssh-keygen(1)</a>
+program contained a bug which caused it to occasionally generate Pubkey
+Authentication (RSA or DSA) keys which had their Most Significant Bit
+(MSB) unset. Such keys were advertised as being full-length, but are
+actually, half the time, smaller than advertised.
+
+<p>
+OpenSSH will print warning messages when it encounters such keys. To rid
+yourself of these message, edit your <i>known_hosts</i> files and replace the
+incorrect key length (usually "1024") with the correct key length
+(usually "1023").
+
+<h2><a name= "2.7">2.7 - X11 and/or agent forwarding does not work.</a></h2>
+
+<p>
+Check your <i>ssh_config</i> and <i>sshd_config</i>. The default
+configuration files disable authentication agent and X11 forwarding. To
+enable it, put the line below in <i>sshd_config</i>:
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+<b>X11Forwarding yes</b>
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<p>
+and put the following lines in <i>ssh_config</i>:
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+<b>ForwardAgent yes</b><br>
+<b>ForwardX11 yes</b>
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<p>
+X11 forwarding requires a working <a
+href="http://www.openbsd.org/cgi-bin/man.cgi?query=xauth&amp;sektion=1"
+>xauth(1)</a> binary. On OpenBSD this is in the <i>xbase</i> file
+set but will probably be different on other platforms. For OpenSSH
+Portable, xauth must be either found at configure time or specified
+via <b>XAuthLocation</b> in sshd_config(5) and ssh_config(5).
+
+<p>
+Note on agent interoperability: There are two different and
+incompatible agent forwarding mechanisms within the SSH2 protocol.
+OpenSSH has always used an extension of the original SSH1 agent
+requests, however some commercial products use a different, non-free
+agent forwarding protocol. This means that agent forwarding cannot
+be used between OpenSSH and those products.
+
+<p>
+<b>NOTE:</b> For users of Linux Mandrake 7.2, Mandrake modifies the
+<i>XAUTHORITY</i> environment variable in <i>/etc/skel/.bashrc</i>,
+and thus any bash user's home directory. This variable is set by OpenSSH
+and for either of the above options to work, you need to comment out
+the line:
+
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+<b># export XAUTHORITY=$HOME/.Xauthority</b>
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<h2><a name= "2.8">2.8 - After upgrading OpenSSH I lost SSH2 support.</a></h2>
+
+<p>
+Between versions changes can be made to <i>sshd_config</i> or
+<i>ssh_config</i>. You should always check on these changes when upgrading
+versions of OpenSSH. After OpenSSH Version 2.3.0 you need to add the
+following to your <i>sshd_config</i>:
+
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+<b>HostKey /etc/ssh_host_dsa_key</b><br>
+<b>HostKey /etc/ssh_host_rsa_key</b>
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<h2><a name= "2.9">2.9 - sftp/scp fails at connection, but ssh is OK.</a></h2>
+
+<p>
+sftp and/or scp may fail at connection time if you have shell
+initialization (.profile, .bashrc, .cshrc, etc) which produces output
+for non-interactive sessions. This output confuses the sftp/scp client.
+You can verify if your shell is doing this by executing:
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+<b>ssh yourhost /usr/bin/true</b>
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<p>
+If the above command produces any output, then you need to modify your
+shell initialization.
+
+<h2><a name= "2.10">2.10 - Will you add [foo] to scp?</a></h2>
+
+<p>
+Short Answer: no.
+
+<p>
+Long Answer: scp is not standardized. The closest thing it has to a
+specification is "what rcp does". Since the same command is used on both ends
+of the connection, adding features or options risks breaking interoperability with other
+implementations.
+
+<p>
+New features are more likely in sftp, since the protocol is standardized
+(well, a <a href="http://www.ietf.org/html.charters/OLD/secsh-charter.html">
+draft standard</a>), extensible, and the client and server are decoupled.
+
+<h2><a name= "2.11">2.11 - How do I use port forwarding?</a></h2>
+
+<p>
+If the remote server is running sshd(8), it may be possible to
+``tunnel'' certain services via ssh. This may be desirable, for
+example, to encrypt POP or SMTP connections, even though the software
+does not directly support encrypted communications. Tunnelling uses
+port forwarding to create a connection between the client and server.
+The client software must be able to specify a non-standard port to
+connect to for this to work.
+
+<p>
+The idea is that the user connects to the remote host using ssh,
+and specifies which port on the client's machine should be used to
+forward connections to the remote server. After that it is possible
+to start the service which is to be encrypted (e.g. fetchmail, irc)
+on the client machine, specifying the same local port passed to
+ssh, and the connection will be tunnelled through ssh. By default,
+the system running the forward will only accept connections from
+itself.
+
+<p>
+The options most relevant to tunnelling are the -L and -R options,
+which allow the user to forward connections, the -D option, which
+permits dynamic port forwarding, the -g option, which permits other
+hosts to use port forwards, and the -f option, which instructs ssh
+to put itself in the background after authentication. See the <a
+href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1"
+>ssh(1)</a> man page for further details.
+
+<p>
+This is an example of tunnelling an IRC session from client machine
+``127.0.0.1'' (localhost) to remote server ``server.example.com'':
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+<b>ssh -f -L 1234:server.example.com:6667 server.example.com sleep 10<br>
+irc -c '#users' -p 1234 pinky 127.0.0.1</b>
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<p>
+This tunnels a connection to IRC server server.example.com, joining
+channel ``#users'', using the nickname ``pinky''. The local port used
+in this example is 1234. It does not matter which port is used, as
+long as it's greater than 1023 (remember, only root can open sockets on
+privileged ports) and doesn't conflict with any ports already in use.
+The connection is forwarded to port 6667 on the remote server, since
+that's the standard port for IRC services.
+
+<p>
+The remote command ``sleep 10'' was specified to allow an amount
+of time (10 seconds, in the example) to start the service which is to
+be tunnelled. If no connections are made within the time specified,
+ssh will exit. If more time is required, the sleep(1) value can be
+increased appropriately or, alternatively, the example above could
+be added as a function to the user's shell. See ksh(1) and csh(1)
+for more details about user-defined functions.
+
+<p>
+ssh also has an -N option, convenient for use with port forwarding:
+if -N is specified, it is not necessary to specify a remote command
+(``sleep 10'' in the example above). However, use of this option
+causes ssh to wait around for ever (as opposed to exiting after a
+remote command has completed), and the user must take care to manually
+kill(1) the process afterwards.
+
+<h2><a name= "2.12">2.12 - My ssh connection freezes or drops out after N minutes of inactivity.</a></h2>
+
+<p>
+This is usually the result of a packet filter or NAT device
+timing out your TCP connection due to inactivity. You can enable
+<b>ClientAliveInterval</b> in the server's <i><a
+href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&amp;sektion=5">
+sshd_config</a></i>, or enable <b>ServerAliveInterval</b> in the
+client's <i><a
+href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh_config&amp;sektion=5">
+ssh_config</a></i> (the latter is available in OpenSSH 3.8 and newer).
+
+<p>
+Enabling either option and setting the interval for less than the time
+it takes to time out your session will ensure that the connection is
+kept "fresh" in the device's connection table.

+
+<b><a

+scp</a></b> will interpret the component before the colon to be a remote
+server name and attempt to connect to it. To prevent this, refer to
+the file by a relative or absolute path, eg:
+
+<blockquote>

+
+<h2><a name= "2.14">2.14 - Why does OpenSSH report its version to clients?</a></h2>
+
+<p>
+OpenSSH, like most SSH implementations, reports its name and version to clients
+when they connect, e.g.
+</p>
+
+<blockquote>
+SSH-2.0-OpenSSH_3.9
+</blockquote>
+
+<p>
+This information is used by clients and servers to enable protocol
+compatibility tweaks to work around changed, buggy or missing features in
+the implementation they are talking to. This protocol feature checking is
+still required at present because versions with incompatibilities are still
+in wide use.

+
+<h2><u><a name= "3.0">3.0 - Portable OpenSSH Questions</a></u></h2>
+
+<h2><a name= "3.1">3.1 - Spurious PAM authentication messages in logfiles.</a></h2>
+
+<p>
+The portable version of OpenSSH will generate spurious authentication
+failures at every login, similar to:
+
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+&quot;<b>authentication failure; (uid=0) -&gt; root for sshd service</b>&quot;
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<p>
+These are generated because OpenSSH first tries to determine whether a
+user needs authentication to login (e.g. empty password). Unfortunately
+PAM likes to log all authentication events, this one included.
+
+<p>
+If it annoys you too much, set &quot;<b>PermitEmptyPasswords no</b>&quot;
+in <i>sshd_config</i>. This will quiet the error message at the expense
+of disabling logins to accounts with no password set.
+This is the default if you use the supplied <i>sshd_config</i> file.
+
+<h2><a name= "3.2">3.2 - Empty passwords not allowed with PAM authentication.</a></h2>
+
+<p>
+To enable empty passwords with a version of OpenSSH built with PAM you
+must add the flag nullok to the end of the password checking module
+in the <i>/etc/pam.d/sshd</i> file. For example:
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+auth required/lib/security/pam_unix.so shadow nodelay nullok
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<p>
+This must be done in addition to setting &quot;<b>PermitEmptyPasswords
+yes</b>&quot; in the <i>sshd_config</i> file.
+
+<p>
+There is one caveat when using empty passwords with PAM authentication:
+PAM will allow any password when authenticating an account with an empty
+password. This breaks the check that
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a>
+uses to determine whether an account has no password set and grant
+users access to the account regardless of the policy specified by
+<b>PermitEmptyPasswords</b>. For this reason, it is recommended that you
+do not add the <b>nullok</b> directive to your PAM configuration file
+unless you specifically wish to allow empty passwords.
+
+
+<h2><a name= "3.3">3.3 - ssh(1) takes a long time to connect or log
+in</a></h2>
+
+<p>
+Large delays (more than 10 seconds) are typically caused by a problem with
+name resolution:
+<ul>
+<li>Some versions of glibc (notably glibc 2.1 shipped with Red Hat 6.1)
+can take a long time to resolve "IPv6 or IPv4" addresses from domain
+names. This can be worked around with by specifying <b>AddressFamily
+inet</b> option in <i>ssh_config</i>.</li>
+
+<li>There may be a DNS lookup problem, either at the client or server.
+You can use the <code>nslookup</code> command to check this on both client
+and server by looking up the other end's name and IP address. In
+addition, on the server look up the name returned by the client's
+IP-name lookup. You can disable most of the server-side lookups by
+setting <b>UseDNS no</b> in <i>sshd_config</i>.</li>
+</ul>
+
+<p>
+Delays less than 10 seconds can have other causes.
+
+<ul>
+
+<li>OpenSSH releases prior to 3.8 had an <i>moduli</i> file with
+moduli that were just smaller than what sshd would look for, and
+as a result, sshd would end up using moduli significantly larger
+than requested, which resulted in a speed penalty. Replacing the
+<i>moduli</i> file will resolve this (note that in most cases this
+file will not be replaced during an upgrade and must be replaced
+manually).</li>
+
+<li>OpenSSH releases prior to 3.8 had a flaw in <code>ssh</code> that
+would cause it to request moduli larger than intended (which when
+combined with the above resulted in significant slowdowns).
+Upgrading the client to 3.8 or higher will resolve this issue.</li>
+
+<li>If either the client or server lack a kernel-based random number
+device (eg Solaris &lt; 9, AIX &lt; 5.2, HP-UX &lt; 11.11) and no
+substitute is available (eg <a href=
+"ftp://ftp.ayamura.org/pub/prngd/">prngd</a>) it's possible that
+one of the programs called by <code>ssh-rand-helper</code> to
+generate entropy is hanging. This can be investigated by running
+it in debug mode:
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+/usr/local/libexec/ssh-rand-helper -vvv
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+Any significant delays should be investigated and rectified, or the
+corresponding commands should be removed from <i>ssh_prng_cmds</i>.
+</li>
+
+</ul>
+
+<h3>How slow is "slow"?</h3>
+Under normal conditions, the speed of SSH logins is dependant on
+CPU speed of client and server. For comparison the following are
+typical connect times for <code>time ssh localhost true</code>
+with a 1024-bit RSA key on otherwise unloaded hosts. OpenSSH and
+OpenSSL were compiled with gcc 3.3.x.

+Either load the appropriate kernel module, enter the correct alias in
+<i>/etc/modules.conf</i> or disable IPv6 in <i>/etc/modules.conf</i>.

+
+<h2><a name= "3.5">3.5 - Password authentication doesn't work (eg on Slackware 7.0 or Red Hat 6.x)</a></h2>
+
+<p>
+If the password is correct password the login is still denied, the
+usual cause is that the system is configured to use MD5-type passwords
+but the
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=crypt&amp;sektion=3"
+>crypt(3)</a> function used by sshd doesn't understand them.
+
+<p>
+Affected accounts will have password strings in <i>/etc/passwd</i>
+or <i>/etc/shadow</i> that start with <b>$1$</b>.
+If password authentication fails for new accounts or accounts with
+recently changed passwords, but works for old accounts, this is the
+likely culprit.
+
+<p>
+The underlying cause is that some versions of OpenSSL have a crypt(3)
+function that does not understand MD5 passwords, and the link order of
+sshd means that OpenSSL's crypt(3) is used instead of the system's.
+OpensSSH's configure attempts to correct for this but is not always
+successful.
+
+<p>
+There are several possible solutions:
+
+<ul>
+<li>
+<p>
+Enable sshd's built-in support for MD5 passwords at build time.
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+./configure --with-md5-passwords [options]
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+This is safe even if you have both types of encryption as sshd will
+select the correct algorithm for each account automatically.
+
+<li>
+<p>
+If your system has a separate libcrypt library (eg Slackware 7) then you
+can manually add -lcrypt to the LIBS list so it's used instead of
+OpenSSL's:
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+LIBS=-lcrypt ./configure [options]
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<li>
+<p>
+If your platforms supports PAM, you may configure sshd to use it
+(see <a href= "#3.15" >section 3.15</a>). This will mean that sshd will
+not verify passwords itself but will defer to the configured PAM modules.
+</ul>
+
+<h2><a name= "3.6">3.6 - Configure or sshd(8) complain about lack of RSA or DSA support</a></h2>

+Ensure that your OpenSSL libraries have been built to include RSA or DSA

+<h2><a name= "3.7">3.7 - "scp: command not found" errors</a></h2>
+
+<p>
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&amp;sektion=1">scp(1)</a>
+must be in the default PATH on both the client and the server. You may
+need to use the <b>--with-default-path</b> option to specify a custom
+path to search on the server. This option replaces the default path,
+so you need to specify all the current directories on your path as well
+as where you have installed scp. For example:
+
+<blockquote>
+<table border=0 width="800">
+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+$ <b>./configure --with-default-path=/bin:/usr/bin:/usr/local/bin:/path/to/scp</b>
+ </td>
+ </tr>
+</table>
+</blockquote>
+
+<p>
+Note that configuration by the server's admin will take precedence over the
+setting of <b>--with-default-path</b>. This includes resetting PATH in
+<i>/etc/profile</i>, PATH in <i>/etc/environment</i> on AIX, or (for 3.7p1 and
+above) setting PATH or SUPATH in <i>/etc/default/login</i> on Solaris or
+Reliant Unix.
+
+<h2><a name= "3.8">3.8 - Unable to read passphrase</a></h2>

+ <tr>
+ <td nowrap bgcolor="#EEEEEE">
+You have no controlling tty. Cannot read passphrase.
+ </td>
+ </tr>

+
+<p>
+OpenSSH may hang when exiting. This can occur when there is an active

+The problem can be verified by doing the following:
+
+<blockquote>
+<table border=0 width="800">
+ <tr>

+</blockquote>
+
+<p>
+A work around for bash users is to place <b>"shopt -s huponexit"</b>
+in either /etc/bashrc or ~/.bashrc. Otherwise, consult your shell's
+man page for an option to enable it to send a HUP signal to active
+jobs when exiting. See <a

+revert to prior behaviour if your older X11 clients do not function
+with this configuration.<p>
+
+In general, X11 clients using X11 R6 should work with the default

+This is true for HP-UX 11.X.<p>
+

+<p>
+Typically this is caused by the file permissions on $HOME, $HOME/.ssh or

+
+To use PAM at all, this option must be provided at build time.
+The run-time behaviour when PAM is built in varies with the version of

+.SH NAME
+gnome\-ssh\-askpass \- prompts a user for a passphrase using GNOME
+.SH SYNOPSIS
+.B gnome\-ssh\-askpass
+.SH DESCRIPTION
+.B gnome\-ssh\-askpass
+is a GNOME-based passphrase dialog for use with OpenSSH.
+It is intended to be called by the
+.BR ssh\-add (1)
+program and not invoked directly.
+It allows
+.BR ssh\-add (1)
+to obtain a passphrase from a user, even if not connected to a terminal
+(assuming that an X display is available).
+This happens automatically in the case where
+.B ssh\-add
+is invoked from one's
+.B ~/.xsession
+or as one of the GNOME startup programs, for example.
+.PP
+In order to be called automatically by
+.BR ssh\-add ,
+.B gnome\-ssh\-askpass
+should be installed as
+.IR /usr/bin/ssh\-askpass .

+The following environment variables are recognized:
+.TP
+.I GNOME_SSH_ASKPASS_GRAB_SERVER
+Causes
+.B gnome\-ssh\-askpass
+to grab the X server before asking for a passphrase.
+.TP
+.I GNOME_SSH_ASKPASS_GRAB_POINTER
+Causes
+.B gnome\-ssh\-askpass
+to grab the mouse pointer using
+.IR gdk_pointer_grab ()
+before asking for a passphrase.
+.PP
+Regardless of whether either of these environment variables is set,
+.B gnome\-ssh\-askpass
+will grab the keyboard using
+.IR gdk_keyboard_grab ().
+.SH AUTHOR
+This manual page was written by Colin Watson <cjwatson@debian.org>
+for the Debian system (but may be used by others).
+It was based on that for
+.B x11\-ssh\-askpass
+by Philip Hands.

+Template: openssh-server/permit-root-login
+Type: boolean
+Default: true
+_Description: Disable SSH password authentication for root?
+ Previous versions of openssh-server permitted logging in as root over SSH
+ using password authentication. The default for new installations is now
+ "PermitRootLogin prohibit-password", which disables password authentication
+ for root without breaking systems that have explicitly configured SSH
+ public key authentication for root.
+ .
+ This change makes systems more secure against brute-force password
+ dictionary attacks on the root user (a very common target for such
+ attacks). However, it may break systems that are set up with the
+ expectation of being able to SSH as root using password authentication. You
+ should only make this change if you do not need to do that.
+
+Template: openssh-server/password-authentication
+Type: boolean
+Default: true
+Description: Allow password authentication?
+ By default, the SSH server will allow authenticating using a password.
+ You may want to change this if all users on this system authenticate using
+ a stronger authentication method, such as public keys.

+Date: Sun, 9 Feb 2014 16:09:48 +0000
+Subject: GSSAPI key exchange support
+
+This patch has been rejected upstream: "None of the OpenSSH developers are
+in favour of adding this, and this situation has not changed for several
+years. This is not a slight on Simon's patch, which is of fine quality, but
+just that a) we don't trust GSSAPI implementations that much and b) we don't
+like adding new KEX since they are pre-auth attack surface. This one is
+particularly scary, since it requires hooks out to typically root-owned
+system resources."
+
+However, quite a lot of people rely on this in Debian, and it's better to
+have it merged into the main openssh package rather than having separate
+-krb5 packages (as we used to have). It seems to have a generally good
+security history.

++Portable OpenSSH with GSSAPI Key Exchange patches
++=================================================
++
++Currently, there are two branches with gssapi key exchange related
++patches:
++
++ * fedora/master: Changes that are shipped in Fedora
++ * debian/master: Changes that are shipped in Debian
++
++The target is to converge to a shared repository with single master
++branch from where we could build releases for both OSes.
++
++
++What is in:
++
++ * The original patch implementing missing parts of RFC4462 by Simon Wilkinson
++ adapted to the current OpenSSH versions and with several fixes
++ * New methods for GSSAPI Kex from IETF draft [1] from Jakub Jelen
++
++
++Missing kerberos-related parts:
++
++ * .k5login and .kusers support available in Fedora [2] [3].
++ * Improved handling of kerberos ccache location [4]
++
++
++[1] https://tools.ietf.org/html/draft-ietf-curdle-gss-keyex-sha2-08
++[2] https://src.fedoraproject.org/rpms/openssh/blob/master/f/openssh-6.6p1-kuserok.patch

+Add compatibility aliases for ProtocolKeepAlives and SetupTimeOut, supported

+
+In batch mode, default ServerAliveInterval to five minutes.

+Subject: Don't check the status field of the OpenSSL version
+
+There is no reason to check the version of OpenSSL (in Debian). If it's
+not compatible the soname will change. OpenSSH seems to want to do a
+check for the soname based on the version number, but wants to keep the
+status of the release the same. Remove that check on the status since
+it doesn't tell you anything about how compatible that version is.

+Subject: Restore TCP wrappers support
+
+Support for TCP wrappers was dropped in OpenSSH 6.7. See this message
+and thread:
+
+ https://lists.mindrot.org/pipermail/openssh-unix-dev/2014-April/032497.html
+
+It is true that 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.
+
+It's not entirely clear what the right long-term answer for Debian is,
+but it at least probably doesn't involve dropping this feature shortly
+before a freeze.

+The IPQoS default changes have some unfortunate interactions with
