Changes with Apache 2.2.22
*) SECURITY: CVE-2011-3368 (cve.mitre.org) Reject requests where the request-URI does not match the HTTP specification, preventing unexpected expansion of target URLs in some reverse proxy configurations. [Joe Orton] *) SECURITY: CVE-2011-3607 (cve.mitre.org) Fix integer overflow in ap_pregsub() which, when the mod_setenvif module is enabled, could allow local users to gain privileges via a .htaccess file. [Stefan Fritsch, Greg Ames] *) SECURITY: CVE-2011-4317 (cve.mitre.org) Resolve additional cases of URL rewriting with ProxyPassMatch or RewriteRule, where particular request-URIs could result in undesired backend network exposure in some configurations. [Joe Orton] *) SECURITY: CVE-2012-0021 (cve.mitre.org) mod_log_config: Fix segfault (crash) when the '%{cookiename}C' log format string is in use and a client sends a nameless, valueless cookie, causing a denial of service. The issue existed since version 2.2.17. PR 52256. [Rainer Canavan ] *) SECURITY: CVE-2012-0031 (cve.mitre.org) Fix scoreboard issue which could allow an unprivileged child process could cause the parent to crash at shutdown rather than terminate cleanly. [Joe Orton] *) SECURITY: CVE-2012-0053 (cve.mitre.org) Fix an issue in error responses that could expose "httpOnly" cookies when no custom ErrorDocument is specified for status code 400. [Eric Covener] *) mod_proxy_ajp: Try to prevent a single long request from marking a worker in error. [Jean-Frederic Clere] *) config: Update the default mod_ssl configuration: Disable SSLv2, only allow >= 128bit ciphers, add commented example for speed optimized cipher list, limit MSIE workaround to MSIE <= 5. [Kaspar Brand] *) core: Fix segfault in ap_send_interim_response(). PR 52315. [Stefan Fritsch] *) mod_log_config: Prevent segfault. PR 50861. [Torsten F�rtsch ] *) mod_win32: Invert logic for env var UTF-8 fixing. Now we exclude a list of vars which we know for sure they dont hold UTF-8 chars; all other vars will be fixed. This has the benefit that now also all vars from 3rd-party modules will be fixed. PR 13029 / 34985. [Guenter Knauf] *) core: Fix hook sorting for Perl modules, a regression introduced in 2.2.21. PR: 45076. [Torsten Foertsch ] *) Fix a regression introduced by the CVE-2011-3192 byterange fix in 2.2.20: A range of '0-' will now return 206 instead of 200. PR 51878. [Jim Jagielski] *) Example configuration: Fix entry for MaxRanges (use "unlimited" instead of "0"). [Rainer Jung] *) mod_substitute: Fix buffer overrun. [Ruediger Pluem, Rainer Jung]...
Changes with Apache 2.2.21
*) SECURITY: CVE-2011-3348 (cve.mitre.org) mod_proxy_ajp: Respond with HTTP_NOT_IMPLEMENTED when the method is not recognized. [Jean-Frederic Clere] *) Fix a regression introduced by the CVE-2011-3192 byterange fix in 2.2.20. PR 51748. [] *) mod_filter: Instead of dropping the Accept-Ranges header when a filter registered with AP_FILTER_PROTO_NO_BYTERANGE is present, set the header value to "none". [Eric Covener, Ruediger Pluem] *) mod_proxy_ajp: Ignore flushing if headers have not been sent. PR 51608 [Ruediger Pluem] *) mod_dav_fs: Fix segfault if apr DBM driver cannot be loaded. PR 51751. [Stefan Fritsch] *) mod_alias: Adjust log severity of "incomplete redirection target" message. PR 44020. *) mod_rewrite: Check validity of each internal (int:) RewriteMap even if the RewriteEngine is disabled in server context, avoiding a crash while referencing the invalid int: map at runtime. PR 50994. [Ben Noordhuis ] *) core: Allow MaxRanges none|unlimited|default and set 'Accept-Ranges: none' in the case Ranges are being ignored with MaxRanges none. [Eric Covener] *) mod_proxy_ajp: Respect "reuse" flag in END_REPONSE packets. [Rainer Jung]
Changes with Apache 2.2.20
*) SECURITY: CVE-2011-3192 (cve.mitre.org) core: Fix handling of byte-range requests to use less memory, to avoid denial of service.

Changes with Apache 2.2.19
*) Revert ABI breakage in 2.2.18 caused by the function signature change of ap_unescape_url_keep2f(). This release restores the signature from 2.2.17 and prior, and introduces ap_unescape_url_keep2f_ex(). [Eric Covener]
Changes with Apache 2.2.18
*) Log an error for failures to read a chunk-size, and return 408 instead 413 when this is due to a read timeout. This change also fixes some cases of two error documents being sent in the response for the same scenario. [Eric Covener] PR49167 *) core: Only log a 408 if it is no keepalive timeout. PR 39785 [Ruediger Pluem, Mark Montague ] *) core: Treat timeout reading request as 408 error, not 400. Log 408 errors in access log as was done in Apache 1.3.x. PR 39785 [Nobutaka Mantani , Stefan Fritsch, Dan Poirier] *) Core HTTP: disable keepalive when the Client has sent Expect: 100-continue but we respond directly with a non-100 response. Keepalive here led to data from clients continuing being treated as a new request. PR 47087. [Nick Kew] *) htpasswd: Change the default algorithm for htpasswd to MD5 on all platforms. Crypt with its 8 character limit is not useful anymore; improve out of disk space handling (PR 30877); print a warning if a password is truncated by crypt. [Stefan Fritsch] *) mod_win32: Added shebang check for '! so that .vbs scripts work as CGI. Win32's cscript interpreter can only use a single quote as comment char. [Guenter Knauf] *) configure: Fix htpasswd/htdbm libcrypt link errors with some newer linkers. [Stefan Fritsch] *) MinGW build improvements. PR 49535. [John Vandenberg , Jeff Trawick] *) mod_ssl, ab: Support OpenSSL compiled without SSLv2 support. [Stefan Fritsch] *) core: AllowEncodedSlashes new option NoDecode to allow encoded slashes in request URL path info but not decode them. PR 35256, PR 46830. [Dan Poirier] *) mod_rewrite: Allow to unset environment variables. PR 50746. [Rainer Jung] *) suEXEC: Add Suexec directive to disable suEXEC without renaming the binary (Suexec Off), or force startup failure if suEXEC is required but not supported (Suexec On). [Jeff Trawick] *) mod_proxy: Put the worker in error state if the SSL handshake with the backend fails. PR 50332. [Daniel Ruggeri , Ruediger Pluem] *) prefork: Update MPM state in children during a graceful restart. Allow the HTTP connection handling loop to terminate early during a graceful restart. PR 41743. [Andrew Punch ] *) mod_ssl: Correctly read full lines in input filter when the line is incomplete during first read. PR 50481. [Ruediger Pluem] *) mod_autoindex: Merge IndexOptions from server to directory context when the directory has no mod_autoindex directives. PR 47766. [Eric Covener] *) mod_cache: Make sure that we never allow a 304 Not Modified response that we asked for to leak to the client should the 304 response be uncacheable. PR45341 [Graham Leggett] *) mod_dav: Send 400 error if malformed Content-Range header is received for a put request (RFC 2616 14.16). PR 49825. [Stefan Fritsch] *) mod_userdir: Add merging of enable, disable, and filename arguments to UserDir directive, leaving enable/disable of userlists unmerged. PR 44076 [Eric Covener] *) core: Honor 'AcceptPathInfo OFF' during internal redirects, such as per-directory mod_rewrite substitutions. PR 50349. [Eric Covener] *) mod_cache: Check the request to determine whether we are allowed to return cached content at all, and respect a "Cache-Control: no-cache" header from a client. Previously, "no-cache" would behave like "max-age=0". [Graham Leggett] *) mod_mem_cache: Add a debug msg when a streaming response exceeds MCacheMaxStreamingBuffer, since mod_cache will follow up with a scary 'memory allocation failed' debug message. PR 49604. [Eric Covener] *) proxy_connect: Don't give up in the middle of a CONNECT tunnel when the child process is starting to exit. PR50220. [Eric Covener]
Changes with Apache 2.2.17
*) prefork MPM: Run cleanups for final request when process exits gracefully to work around a flaw in apr-util. PR 43857. [Tom Donovan] *) mod_reqtimeout: Do not wrongly enforce timeouts for mod_proxy's backend connections and other protocol handlers (like mod_ftp). Enforce the timeout for AP_MODE_GETLINE. If there is a timeout, shorten the lingering close time from 30 to 2 seconds. [Stefan Fritsch] *) Proxy balancer: support setting error status according to HTTP response code from a backend. PR 48939. [Daniel Ruggeri ] *) mod_authnz_ldap: If AuthLDAPCharsetConfig is set, also convert the password to UTF-8. PR 45318. [Johannes Müller , Stefan Fritsch] *) core: check symlink ownership if both FollowSymlinks and SymlinksIfOwnerMatch are set [Nick Kew] *) core: fix origin checking in SymlinksIfOwnerMatch PR 36783 [Robert L Mathews ] *) mod_headers: Enable multi-match-and-replace edit option PR 46594 [Nick Kew] *) mod_log_config: Make ${cookie}C correctly match whole cookie names instead of substrings. PR 28037. [Dan Franklin , Stefan Fritsch] *) mod_dir, mod_negotiation: Pass the output filter information to newly created sub requests; as these are later on used as true requests with an internal redirect. This allows for mod_cache et.al. to trap the results of the redirect. PR 17629, 43939 [Dirk-Willem van Gulik, Jim Jagielski, Joe Orton, Ruediger Pluem] *) rotatelogs: Fix possible buffer overflow if admin configures a mongo log file path. [Jeff Trawick] *) mod_ssl: Do not do overlapping memcpy. PR 45444 [Joe Orton] *) vhost: A purely-numeric Host: header should not be treated as a port. PR 44979 [Nick Kew] *) core: (re)-introduce -T commandline option to suppress documentroot check at startup. PR 41887 [Jan van den Berg ]
Changes with Apache 2.2.16

PR: 49417. [Rainer Jung] *) core: Filter init functions are now run strictly once per request before handler invocation. The init functions are no longer run for connection filters. PR 49328. [Joe Orton] *) mod_filter: enable it to act on non-200 responses. PR 48377 [Nick Kew] *) mod_ldap: LDAP caching was suppressed (and ldap-status handler returns title page only) when any mod_ldap directives were used in VirtualHost context. [Eric Covener] *) mod_ssl: Fix segfault at startup if proxy client certs are shared across multiple vhosts. PR 39915. [Joe Orton] *) mod_proxy_http: Log the port of the remote server in various messages. PR 48812. [Igor Galić ] *) apxs: Fix -A and -a options to ignore whitespace in httpd.conf [Philip M. Gollucci] *) mod_dir: add FallbackResource directive, to enable admin to specify an action to happen when a URL maps to no file, without resorting to ErrorDocument or mod_rewrite. PR 47184 [Nick Kew] *) mod_rewrite: Allow to set environment variables without explicitely giving a value. [Rainer Jung]
Changes with Apache 2.2.15
*) SECURITY: CVE-2009-3555 (cve.mitre.org) mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection attack when compiled against OpenSSL version 0.9.8m or later. Introduces the 'SSLInsecureRenegotiation' directive to reopen this vulnerability and offer unsafe legacy renegotiation with clients which do not yet support the new secure renegotiation protocol, RFC 5746. [Joe Orton, and with thanks to the OpenSSL Team] *) SECURITY: CVE-2009-3555 (cve.mitre.org) mod_ssl: A partial fix for the TLS renegotiation prefix injection attack by rejecting any client-initiated renegotiations. Forcibly disable keepalive for the connection if there is any buffered data readable. Any configuration which requires renegotiation for per-directory/location access control is still vulnerable, unless using OpenSSL >= 0.9.8l. [Joe Orton, Ruediger Pluem, Hartmut Keil ] *) SECURITY: CVE-2010-0408 (cve.mitre.org) mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent when request headers indicate a request body is incoming; not a case of HTTP_INTERNAL_SERVER_ERROR. [Niku Toivola ] *) SECURITY: CVE-2010-0425 (cve.mitre.org) mod_isapi: Do not unload an isapi .dll module until the request processing is completed, avoiding orphaned callback pointers. [Brett Gervasoni , Jeff Trawick] *) SECURITY: CVE-2010-0434 (cve.mitre.org) Ensure each subrequest has a shallow copy of headers_in so that the parent request headers are not corrupted. Elimiates a problematic optimization in the case of no request body. PR 48359 [Jake Scott, William Rowe, Ruediger Pluem] *) mod_reqtimeout: New module to set timeouts and minimum data rates for receiving requests from the client. [Stefan Fritsch] *) mod_proxy_ajp: Really regard the operation a success, when the client aborted the connection. In addition adjust the log message if the client aborted the connection. [Ruediger Pluem] *) mod_negotiation: Preserve query string over multiviews negotiation. This buglet was fixed for type maps in 2.2.6, but the same issue affected multiviews and was overlooked. PR 33112 [Joergen Thomsen ] *) mod_cache: Introduce the thundering herd lock, a mechanism to keep the flood of requests at bay that strike a backend webserver as a cached entity goes stale. [Graham Leggett] *) mod_proxy_http: Make sure that when an ErrorDocument is served from a reverse proxied URL, that the subrequest respects the status of the original request. This brings the behaviour of proxy_handler in line with default_handler. PR 47106. [Graham Leggett] *) mod_log_config: Add the R option to log the handler used within the request. [Christian Folini ] *) mod_include: Allow fine control over the removal of Last-Modified and ETag headers within the INCLUDES filter, making it possible to cache responses if desired.

[Joe Orton] *) core: Fix potential memory leaks by making sure to not destroy bucket brigades that have been created by earlier filters. [Stefan Fritsch] *) mod_authnz_ldap: Add AuthLDAPBindAuthoritative to allow Authentication to try other providers in the case of an LDAP bind failure. PR 46608 [Justin Erenkrantz, Joe Schaefer, Tony Stevenson] *) mod_proxy, mod_proxy_http: Support remote https proxies by using HTTP CONNECT. PR 19188. [Philippe Dutrueux , Rainer Jung] *) worker: Don't report server has reached MaxClients until it has. Add message when server gets within MinSpareThreads of MaxClients. PR 46996. [Dan Poirier] *) mod_ssl: When extracting certificate subject/issuer names to the SSL_*_DN_* variables, handle RDNs with duplicate tags by exporting multiple varialables with an "_n" integer suffix. PR 45875. [Joe Orton, Peter Sylvester ] *) mod_authnz_ldap: Failures to map a username to a DN, or to check a user password now result in an informational level log entry instead of warning level. [Eric Covener] *) core: Preserve Port information over internal redirects PR 35999 [Jonas Ringh ] *) mod_filter: fix FilterProvider matching where "dispatch" string doesn't exist. PR 48054 [] *) Build: fix --with-module to work as documented PR 43881 [Gez Saunders ] *) mod_mime: Make RemoveType override the info from TypesConfig. PR 38330.

PR 46971 [evanc nortel.com] *) mod_charset_lite: Honor 'CharsetOptions NoImplicitAdd'. [Eric Covener] *) mod_ldap: If LDAPSharedCacheSize is too small, try harder to purge some cache entries and log a warning. Also increase the default LDAPSharedCacheSize to 500000. This is a more realistic size suitable for the default values of 1024 for LdapCacheEntries/LdapOpCacheEntries. PR 46749. [Stefan Fritsch] *) mod_disk_cache, mod_mem_cache: don't cache incomplete responses, per RFC 2616, 13.8. PR15866.

PR 47928 [Bill Zajac ] *) mod_cache: correctly consider s-maxage in cacheability decisions. [Dan Poirier] *) core: Return APR_EOF if request body is shorter than the length announced by the client. PR 33098 [ Stefan Fritsch ] *) mod_rewrite: Add scgi scheme detection. [André Malo] *) mod_mime: Detect invalid use of MultiviewsMatch inside Location and LocationMatch sections. PR 47754.
