3 Changes with Apache 2.3.9
5 *) SECURITY: CVE-2010-1623 (cve.mitre.org)
6 Fix a denial of service attack against mod_reqtimeout.
9 *) mod_ssl: Make sure to always log an error if loading of CA certificates
10 fails. PR 40312. [Paul Tiemann <issues apache org ourdetour com>]
12 *) mod_dav: Send 501 error if unknown Content-* header is received for a PUT
13 request (RFC 2616 9.6). PR 42978. [Stefan Fritsch]
15 *) mod_dav: Send 400 error if malformed Content-Range header is received for
16 a put request (RFC 2616 14.16). PR 49825. [Stefan Fritsch]
18 *) mod_proxy: Release the backend connection as soon as EOS is detected,
19 so the backend isn't forced to wait for the client to eventually
20 acknowledge the data. [Graham Leggett]
22 *) mod_proxy: Optimise ProxyPass within a Location so that it is stored
23 per-directory, and chosen during the location walk. Make ProxyPass
24 work correctly from within a LocationMatch. [Graham Leggett]
26 *) core: Fix segfault if per-module LogLevel is on virtual host
27 scope. PR 50117. [Stefan Fritsch]
29 *) mod_proxy: Move the ProxyErrorOverride directive to have per
30 directory scope. [Graham Leggett]
32 *) mod_allowmethods: New module to deny certain HTTP methods without
33 interfering with authentication/authorization. [Paul Querna,
34 Igor Galić, Stefan Fritsch]
36 *) mod_ssl: Log certificate information and improve error message if client
37 cert verification fails. PR 50093, PR 50094. [Lassi Tuura <lat cern ch>,
40 *) htcacheclean: Teach htcacheclean to limit cache size by number of
41 inodes in addition to size of files. Prevents a cache disk from
42 running out of space when many small files are cached.
45 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
46 describes more accurately what the directive does. The old name
47 still works but logs a warning. [Stefan Fritsch]
49 *) mod_cache: Optionally serve stale data when a revalidation returns a
50 5xx response, controlled by the CacheStaleOnError directive.
53 *) htcacheclean: Allow the listing of valid URLs within the cache, with
54 the option to list entry metadata such as sizes and times. [Graham
57 *) mod_cache: Allow control over the base URL of reverse proxied requests
58 using the CacheKeyBaseURL directive, so that the cache key can be
59 calculated from the endpoint URL instead of the server URL. [Graham
62 *) mod_cache: CacheLastModifiedFactor, CacheStoreNoStore, CacheStorePrivate,
63 CacheStoreExpired, CacheIgnoreNoLastMod, CacheDefaultExpire,
64 CacheMinExpire and CacheMaxExpire can be set per directory/location.
67 *) mod_disk_cache: CacheMaxFileSize, CacheMinFileSize, CacheReadSize and
68 CacheReadTime can be set per directory/location. [Graham Leggett]
70 *) core: Speed up config parsing if using a very large number of config
71 files. PR 50002 [andrew cloudaccess net]
73 *) mod_cache: Support the caching of HEAD requests. [Graham Leggett]
75 *) htcacheclean: Allow the option to round up file sizes to a given
76 block size, improving the accuracy of disk usage. [Graham Leggett]
78 *) mod_ssl: Add authz providers for use with mod_authz_core and its
79 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
80 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
81 'ssl-require' (expressions with same syntax as SSLRequire).
84 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
85 bison instead of yacc. [Stefan Fritsch]
87 *) mod_disk_cache: Change on-disk header file format to support the
88 link of the device/inode of the data file to the matching header
89 file, and to support the option of not writing a data file when
90 the data file is empty. [Graham Leggett]
92 *) core/mod_unique_id: Add generate_log_id hook to allow to use
93 the ID generated by mod_unique_id as error log ID for requests.
96 *) mod_cache: Make sure that we never allow a 304 Not Modified response
97 that we asked for to leak to the client should the 304 response be
98 uncacheable. PR45341 [Graham Leggett]
100 *) mod_cache: Add the cache_status hook to register the final cache
101 decision hit/miss/revalidate. Add optional support for an X-Cache
102 and/or an X-Cache-Detail header to add the cache status to the
103 response. PR48241 [Graham Leggett]
105 *) mod_authz_host: Add 'local' provider that matches connections originating
106 on the local host. PR 19938. [Stefan Fritsch]
108 *) Event MPM: Fix crash accessing pollset on worker thread when child
109 process is exiting. [Jeff Trawick]
111 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
112 pass the system library path (LD_LIBRARY_PATH or platform-specific
113 variables) along with the system PATH, by default. Both should be
114 overridden together as desired using PassEnv etc; see mod_env.
117 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
118 capture a stale backend response, perform If-Modified-Since requests
119 against the backend, and serving from the cache all 304 responses.
120 This restores pre-2.2.4 cache behavior. [William Rowe]
122 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
123 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
124 the ambiguity of the symlink test "-ltest", introduce -h or -L as
125 symlink test operators. [William Rowe]
127 *) mod_cache: Give the cache provider the opportunity to choose to cache
128 or not cache based on the buckets present in the brigade, such as the
129 presence of a FILE bucket.
132 *) mod_authz_core: Allow authz providers to check args while reading the
133 config and allow to cache parsed args. Move 'all' and 'env' authz
134 providers from mod_authz_host to mod_authz_core. Add 'method' authz
135 provider depending on the HTTP method. [Stefan Fritsch]
137 *) mod_include: Move the request_rec within mod_include to be
138 exposed within include_ctx_t. [Graham Leggett]
140 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
141 variable being echoed or set to be decoded and then encoded as separate
142 steps. PR47686 [Graham Leggett]
144 *) mod_cache: Add a discrete commit_entity() provider function within the
145 mod_cache provider interface which is called to indicate to the
146 provider that caching is complete, giving the provider the opportunity
147 to commit temporary files permanently to the cache in an atomic
148 fashion. Replace the inconsistent use of error cleanups with a formal
149 set of pool cleanups attached to a subpool, which is destroyed on error.
152 *) mod_cache: Change the signature of the store_body() provider function
153 within the mod_cache provider interface to support an "in" brigade
154 and an "out" brigade instead of just a single input brigade. This
155 gives a cache provider the option to consume only part of the brigade
156 passed to it, rather than the whole brigade as was required before.
157 This fixes an out of memory and a request timeout condition that would
158 occur when the original document was a large file. Introduce
159 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
160 the amount of data to attempt to cache at a time. [Graham Leggett]
162 *) core: Add ErrorLogFormat to allow configuring error log format, including
163 additional information that is logged once per connection or request. Add
164 error log IDs for connections and request to allow correlating error log
165 lines and the corresponding access log entry. [Stefan Fritsch]
167 *) core: Disable sendfile by default. [Stefan Fritsch]
169 *) mod_cache: Check the request to determine whether we are allowed
170 to return cached content at all, and respect a "Cache-Control:
171 no-cache" header from a client. Previously, "no-cache" would
172 behave like "max-age=0". [Graham Leggett]
174 *) mod_cache: Use a proper filter context to hold filter data instead
175 of misusing the per-request configuration. Fixes a segfault on trunk
176 when the normal handler is used. [Graham Leggett]
178 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
179 it is too long. PR 49388. [Stefan Fritsch]
181 *) vhosts: Do not allow _default_ in NameVirtualHost, or mixing *
182 and non-* ports on NameVirtualHost, or multiple NameVirtualHost
183 directives for the same address:port, or NameVirtualHost
184 directives with no matching VirtualHosts, or multiple ip-based
185 VirtualHost sections for the same address:port. These were
186 previously accepted with a warning, but the behavior was
187 undefined. [Dan Poirier]
189 *) mod_remoteip: Fix a segfault when using mod_remoteip in conjunction with
190 Allow/Deny. PR 49838. [Andrew Skalski <voltara gmail.com>]
192 *) core: DirectoryMatch can now match on the end of line character ($),
193 and sub-directories of matched directories are no longer implicitly
194 matched. PR49809 [Eric Covener]
196 *) Regexps: introduce new higher-level regexp utility including parsing
197 and executing perl-style regexp ops (e.g s/foo/bar/i) and regexp memory
200 Changes with Apache 2.3.8
202 *) suexec: Support large log files. PR 45856. [Stefan Fritsch]
204 *) core: Abort with sensible error message if no or more than one MPM is
205 loaded. [Stefan Fritsch]
207 *) mod_proxy: Rename erroronstatus to failonstatus.
208 [Daniel Ruggeri <DRuggeri primary.net>]
210 *) mod_dav_fs: Fix broken "creationdate" property.
211 Regression in version 2.3.7. [Rainer Jung]
213 Changes with Apache 2.3.7
215 *) SECURITY: CVE-2010-1452 (cve.mitre.org)
216 mod_dav, mod_cache, mod_session: Fix Handling of requests without a path
217 segment. PR: 49246 [Mark Drayton, Jeff Trawick]
219 *) mod_ldap: Properly check the result returned by apr_ldap_init. PR 46076.
222 *) mod_rewrite: Log errors if rewrite map files cannot be opened. PR 49639.
225 *) mod_proxy_http: Support the 'ping' property for backend HTTP/1.1 servers
226 via leveraging 100-Continue as the initial "request".
229 *) core/mod_authz_core: Introduce new access_checker_ex hook that enables
230 mod_authz_core to bypass authentication if access should be allowed by
231 IP address/env var/... [Stefan Fritsch]
233 *) core: Introduce note_auth_failure hook to allow modules to add support
234 for additional auth types. This makes ap_note_auth_failure() work with
235 mod_auth_digest again. PR 48807. [Stefan Fritsch]
237 *) socache modules: return APR_NOTFOUND when a lookup is not found [Nick Kew]
239 *) mod_authn_cache: new module [Nick Kew]
241 *) configure: Add reallyall option for --enable-mods-shared. [Stefan Fritsch]
243 *) Fix Windows build when using VC6. [Gregg L. Smith <lists glewis com>]
245 *) mod_rewrite: Allow to set environment variables without explicitly
246 giving a value. [Rainer Jung]
248 *) mod_rewrite: Remove superfluous EOL from rewrite logging. [Rainer Jung]
250 *) mod_include: recognise "text/html; parameters" as text/html
251 PR 49616 [Andrey Chernov <ache nagual.pp.ru>]
253 *) CGI vars: allow PATH to be set by SetEnv, consistent with LD_LIBRARY_PATH
256 *) Core: Extra robustness: don't try authz and segfault if authn
257 fails to set r->user. Log bug and return 500 instead.
260 *) HTTP protocol filter: fix handling of longer chunk extensions
261 PR 49474 [<tee.bee gmx.de>]
263 *) Update SSL cipher suite and add example for SSLHonorCipherOrder.
264 [Lars Eilebrecht, Rainer Jung]
266 *) move AddOutputFilterByType from core to mod_filter. This should
267 fix nasty side-effects that happen when content_type is set
268 more than once in processing a request, and make it fully
269 compatible with dynamic and proxied contents. [Nick Kew]
271 *) mod_log_config: Implement logging for sub second timestamps and
272 request end time. [Rainer Jung]
274 Changes with Apache 2.3.6
276 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
277 mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
278 attack when compiled against OpenSSL version 0.9.8m or later. Introduces
279 the 'SSLInsecureRenegotiation' directive to reopen this vulnerability
280 and offer unsafe legacy renegotiation with clients which do not yet
281 support the new secure renegotiation protocol, RFC 5746.
282 [Joe Orton, and with thanks to the OpenSSL Team]
284 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
285 mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
286 by rejecting any client-initiated renegotiations. Forcibly disable
287 keepalive for the connection if there is any buffered data readable. Any
288 configuration which requires renegotiation for per-directory/location
289 access control is still vulnerable, unless using OpenSSL >= 0.9.8l.
290 [Joe Orton, Ruediger Pluem, Hartmut Keil <Hartmut.Keil adnovum.ch>]
292 *) SECURITY: CVE-2010-0408 (cve.mitre.org)
293 mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent
294 when request headers indicate a request body is incoming; not a case of
295 HTTP_INTERNAL_SERVER_ERROR. [Niku Toivola <niku.toivola sulake.com>]
297 *) SECURITY: CVE-2010-0425 (cve.mitre.org)
298 mod_isapi: Do not unload an isapi .dll module until the request
299 processing is completed, avoiding orphaned callback pointers.
300 [Brett Gervasoni <brettg senseofsecurity.com>, Jeff Trawick]
302 *) core: Filter init functions are now run strictly once per request
303 before handler invocation. The init functions are no longer run
304 for connection filters. PR 49328. [Joe Orton]
306 *) core: Adjust the output filter chain correctly in an internal
307 redirect from a subrequest, preserving filters from the main
308 request as necessary. PR 17629. [Joe Orton]
310 *) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
311 Response if they so choose to do so. Previously an attempt to cache a 206
312 was arbitrarily allowed if the response contained an Expires or
313 Cache-Control header, and arbitrarily denied if both headers were missing.
316 *) core: Add microsecond timestamp fractions, process id and thread id
317 to the error log. [Rainer Jung]
319 *) configure: The "most" module set gets build by default. [Rainer Jung]

331 APR Util 1.x crypto. [Rainer Jung]
333 *) ab: Fix memory leak with -v2 and SSL. PR 49383.
334 [Pavel Kankovsky <peak argo troja mff cuni cz>]
336 *) core: Add per-module and per-directory loglevel configuration.
337 Add some more trace logging.
338 mod_rewrite: Replace RewriteLog/RewriteLogLevel with trace log levels.
339 mod_ssl: Replace LogLevelDebugDump with trace log levels.
340 mod_ssl/mod_proxy*: Adjust loglevels to be less verbose at levels info
342 mod_dumpio: Replace DumpIOLogLevel with trace log levels.
345 *) mod_ldap: LDAP caching was suppressed (and ldap-status handler returns
346 title page only) when any mod_ldap directives were used in VirtualHost
347 context. [Eric Covener]
349 *) mod_disk_cache: Decline the opportunity to cache if the response is
350 a 206 Partial Content. This stops a reverse proxied partial response
351 from becoming cached, and then being served in subsequent responses.
354 *) mod_deflate: avoid the risk of forwarding data before headers are set.
355 PR 49369 [Matthew Steele <mdsteele google.com>]
357 *) mod_authnz_ldap: Ensure nested groups are checked when the
358 top-level group doesn't have any direct non-group members
359 of attributes in AuthLDAPGroupAttribute. [Eric Covener]
361 *) mod_authnz_ldap: Search or Comparison during authorization phase
362 can use the credentials from the authentication phase
363 (AuthLDAPSearchAsUSer,AuthLDAPCompareAsUser).
364 PR 48340 [Domenico Rotiroti, Eric Covener]
366 *) mod_authnz_ldap: Allow the initial DN search during authentication
367 to use the HTTP username/pass instead of an anonymous or hard-coded
368 LDAP id (AuthLDAPInitialBindAsUser, AuthLDAPInitialBindPattern).
371 *) mod_authnz_ldap: Publish requested LDAP data with an AUTHORIZE_ prefix
372 when this module is used for authorization. See AuthLDAPAuthorizePrefix.
373 PR 45584 [Eric Covener]

382 [Bryn Dole <dole blekko.com>]
384 *) Log an error for failures to read a chunk-size, and return 408 instead of

389 *) mod_proxy_balancer: Add new directive BalancerNonce to allow admin
390 to control/set the nonce used in the balancer-manager application.

410 *) Introduce SSLFIPS directive to support OpenSSL FIPS_mode; permits all
411 builds of mod_ssl to use 'SSLFIPS off' for portability, but the proper
412 build of openssl is required for 'SSLFIPS on'. PR 46270.

422 aborted the connection. In addition adjust the log message if the client
423 aborted the connection. [Ruediger Pluem]
425 *) mod_ssl: Add the 'SSLInsecureRenegotiation' directive, which
426 allows insecure renegotiation with clients which do not yet
