PR 61574. + [Joe Orton] + + *) mod_xml2enc: Update check to accept any text/ media type + or any XML media type per RFC 7303, avoiding + corruption of Microsoft OOXML formats. PR 64339. + [Joseph Heenan <joseph.heenan fintechlabs.io>, Joe Orton] + + *) mod_http2: v2.0.26 with the following fixes: + - Fixed `Date` header on requests upgraded from HTTP/1.1 (h2c). Fixes + <https://github.com/icing/mod_h2/issues/272>. + - Fixed small memory leak in h2 header bucket free. Thanks to + Michael Kaufmann for finding this and providing the fix. + + *) htcacheclean: In -a/-A mode, list all files per subdirectory + rather than only one. PR 65091. + [Artem Egorenkov <aegorenkov.91 gmail.com>] + + *) mod_ssl: SSLProxyMachineCertificateFile/Path may reference files + which include CA certificates; those CA certs are treated as if + configured with SSLProxyMachineCertificateChainFile. [Joe Orton] + + *) htpasswd, htdbm, dbmmanage: Update help&docs to refer to + "hashing", rather than "encrypting" passwords. + [Michele Preziuso <mpreziuso kaosdynamics.com>] + + *) mod_ssl: Fix build with LibreSSL 2.0.7+. PR 64047. + [Giovanni Bechis, Yann Ylavic] + + *) htpasswd: Add support for passwords using SHA-2. [Joe Orton, + Yann Ylavic] + + *) core: Allow mod_env to override system environment vars. [Joe Orton] + + *) Allow mod_dav_fs to tolerate race conditions between PROPFIND and an + operation which removes a directory/file between apr_dir_read() and + apr_stat(). Current behaviour is to abort the connection which seems + inferior to tolerating (and logging) the error. [Joe Orton] + + *) mod_ldap: HTML-escape data in the ldap-status handler. + [Eric Covener, Chamal De Silva] + + *) mod_ssl: Disable the OpenSSL ENGINE API when OPENSSL_NO_ENGINE is set. + Allow for "SSLCryptoDevice builtin" if the ENGINE API is not available, + notably with OpenSSL >= 3. PR 68080. [Yann Ylavic, Joe Orton] + + *) mod_ssl: Improve compatibility with OpenSSL 3, fix build warnings about + deprecated ENGINE_ API, honor OPENSSL_API_COMPAT setting while defaulting + to compatibitily with version 1.1.1 (including ENGINEs / SSLCryptoDevice). + [Yann Ylavic] + + *) mod_ssl: release memory to the OS when needed. [Giovanni Bechis] + + *) mod_proxy: Ignore (and warn about) enablereuse=on for ProxyPassMatch when + some dollar substitution (backreference) happens in the hostname or port + part of the URL. [Yann Ylavic] + + *) mod_proxy: Allow to set a TTL for how long DNS resolutions to backend + systems are cached. [Yann Ylavic] + + *) mod_proxy: Add optional third argument for ProxyRemote, which + configures Basic authentication credentials to pass to the remote + proxy. PR 37355. [Joe Orton] + Changes with Apache 2.4.58 + *) SECURITY: CVE-2023-45802: Apache HTTP Server: HTTP/2 stream + memory not reclaimed right away on RST (cve.mitre.org) + When a HTTP/2 stream was reset (RST frame) by a client, there + was a time window were the request's memory resources were not + reclaimed immediately. Instead, de-allocation was deferred to + connection close. A client could send new requests and resets, + keeping the connection busy and open and causing the memory + footprint to keep on growing. On connection close, all resources + were reclaimed, but the process might run out of memory before + that. + This was found by the reporter during testing of CVE-2023-44487 + (HTTP/2 Rapid Reset Exploit) with their own test client. During + "normal" HTTP/2 use, the probability to hit this bug is very + low. The kept memory would not become noticeable before the + connection closes or times out. + Users are recommended to upgrade to version 2.4.58, which fixes + the issue. + Credits: Will Dormann of Vul Labs + + *) SECURITY: CVE-2023-43622: Apache HTTP Server: DoS in HTTP/2 with + initial windows size 0 (cve.mitre.org) + An attacker, opening a HTTP/2 connection with an initial window + size of 0, was able to block handling of that connection + indefinitely in Apache HTTP Server. This could be used to + exhaust worker resources in the server, similar to the well + known "slow loris" attack pattern. + This has been fixed in version 2.4.58, so that such connection + are terminated properly after the configured connection timeout. + This issue affects Apache HTTP Server: from 2.4.55 through + 2.4.57. + Users are recommended to upgrade to version 2.4.58, which fixes + the issue. + Credits: Prof. Sven Dietrich (City University of New York) + + *) SECURITY: CVE-2023-31122: mod_macro buffer over-read + (cve.mitre.org) + Out-of-bounds Read vulnerability in mod_macro of Apache HTTP + Server.This issue affects Apache HTTP Server: through 2.4.57. + Credits: David Shoon (github/davidshoon) + *) mod_ssl: Silence info log message "SSL Library Error: error:0A000126: SSL routines::unexpected eof while reading" when using OpenSSL 3 by setting SSL_OP_IGNORE_UNEXPECTED_EOF if |
