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.

[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 ]

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]

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'

the original file, ignore the ranges and send the complete file.
PR 51714. [Stefan Fritsch, Jim Jagielski, Ruediger Pluem, Eric Covener]
*) mod_authnz_ldap: If the LDAP server returns constraint violation,
don't treat this as an error but as "auth denied". [Stefan Fritsch]

state after a timeout when discarding a request body. PR 51103.
[Stefan Fritsch]
*) core: Do the hook sorting earlier so that the hooks are properly sorted
for the pre_config hook and during parsing the config. [Stefan Fritsch]
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.

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]

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]

for platforms Windows, Netware and OS2. 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.

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. Fix the default value of the SSIAccessEnable
directive. [Graham Leggett]
*) mod_ssl: Fix a potential I/O hang if a long list of trusted CAs
is configured for client cert auth. PR 46952. [Joe Orton]

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

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
