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 *) suEXEC: Add Suexec directive to disable suEXEC without renaming the
10 binary (Suexec Off), or force startup failure if suEXEC is required
11 but not supported (Suexec On). Change SuexecUserGroup to fail
12 startup instead of just printing a warning if suEXEC is disabled.
15 *) core: Add Error directive for aborting startup or htaccess processing
16 with a specified error message. [Jeff Trawick]
18 *) mod_rewrite: Fix the RewriteEngine directive to work within a
19 location. Previously, once RewriteEngine was switched on globally,
20 it was impossible to switch off. [Graham Leggett]
22 *) core, mod_include, mod_ssl: Move the expression parser derived from
23 mod_include back into mod_include. Replace ap_expr with a parser
24 derived from mod_ssl's parser. Make mod_ssl use the new parser. Rework
25 ap_expr's public interface and provide hooks for modules to add variables
26 and functions. [Stefan Fritsch]
28 *) core: Do the hook sorting earlier so that the hooks are properly sorted
29 for the pre_config hook and during parsing the config. [Stefan Fritsch]
31 *) core: In the absence of any AllowOverride directives, the default is now
32 "None" instead of "All". PR49823 [Eric Covener]
34 *) mod_proxy: Don't allow ProxyPass or ProxyPassReverse in
35 <Directory> or <Files>. PR47765 [Eric Covener]
37 *) prefork/worker/event MPMS: default value (when no directive is present)
38 of MaxConnectionsPerChild/MaxRequestsPerChild is changed to 0 from 10000
39 to match default configuration and manual. PR47782 [Eric Covener]
41 *) proxy_connect: Don't give up in the middle of a CONNECT tunnel
42 when the child process is starting to exit. PR50220. [Eric Covener]
44 *) mod_autoindex: Fix inheritance of mod_autoindex directives into
45 contexts that don't have any mod_autoindex directives. PR47766.
48 *) mod_rewrite: Add END flag for RewriteRule to prevent further rounds
49 of rewrite processing when a per-directory substitution occurs.
52 *) mod_ssl: Make sure to always log an error if loading of CA certificates
53 fails. PR 40312. [Paul Tiemann <issues apache org ourdetour com>]
55 *) mod_dav: Send 501 error if unknown Content-* header is received for a PUT
56 request (RFC 2616 9.6). PR 42978. [Stefan Fritsch]
58 *) mod_dav: Send 400 error if malformed Content-Range header is received for
59 a put request (RFC 2616 14.16). PR 49825. [Stefan Fritsch]
61 *) mod_proxy: Release the backend connection as soon as EOS is detected,
62 so the backend isn't forced to wait for the client to eventually
63 acknowledge the data. [Graham Leggett]
65 *) mod_proxy: Optimise ProxyPass within a Location so that it is stored
66 per-directory, and chosen during the location walk. Make ProxyPass
67 work correctly from within a LocationMatch. [Graham Leggett]
69 *) core: Fix segfault if per-module LogLevel is on virtual host
70 scope. PR 50117. [Stefan Fritsch]
72 *) mod_proxy: Move the ProxyErrorOverride directive to have per
73 directory scope. [Graham Leggett]
75 *) mod_allowmethods: New module to deny certain HTTP methods without
76 interfering with authentication/authorization. [Paul Querna,
77 Igor Galić, Stefan Fritsch]
79 *) mod_ssl: Log certificate information and improve error message if client
80 cert verification fails. PR 50093, PR 50094. [Lassi Tuura <lat cern ch>,
83 *) htcacheclean: Teach htcacheclean to limit cache size by number of
84 inodes in addition to size of files. Prevents a cache disk from
85 running out of space when many small files are cached.
88 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
89 describes more accurately what the directive does. The old name
90 still works but logs a warning. [Stefan Fritsch]
92 *) mod_cache: Optionally serve stale data when a revalidation returns a
93 5xx response, controlled by the CacheStaleOnError directive.
96 *) htcacheclean: Allow the listing of valid URLs within the cache, with
97 the option to list entry metadata such as sizes and times. [Graham
100 *) mod_cache: correctly parse quoted strings in cache headers.
103 *) mod_cache: Allow control over the base URL of reverse proxied requests
104 using the CacheKeyBaseURL directive, so that the cache key can be
105 calculated from the endpoint URL instead of the server URL. [Graham
108 *) mod_cache: CacheLastModifiedFactor, CacheStoreNoStore, CacheStorePrivate,
109 CacheStoreExpired, CacheIgnoreNoLastMod, CacheDefaultExpire,
110 CacheMinExpire and CacheMaxExpire can be set per directory/location.
113 *) mod_disk_cache: CacheMaxFileSize, CacheMinFileSize, CacheReadSize and
114 CacheReadTime can be set per directory/location. [Graham Leggett]
116 *) core: Speed up config parsing if using a very large number of config
117 files. PR 50002 [andrew cloudaccess net]
119 *) mod_cache: Support the caching of HEAD requests. [Graham Leggett]
121 *) htcacheclean: Allow the option to round up file sizes to a given
122 block size, improving the accuracy of disk usage. [Graham Leggett]
124 *) mod_ssl: Add authz providers for use with mod_authz_core and its
125 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
126 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
127 'ssl-require' (expressions with same syntax as SSLRequire).
130 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
131 bison instead of yacc. [Stefan Fritsch]
133 *) mod_disk_cache: Change on-disk header file format to support the
134 link of the device/inode of the data file to the matching header
135 file, and to support the option of not writing a data file when
136 the data file is empty. [Graham Leggett]
138 *) core/mod_unique_id: Add generate_log_id hook to allow to use
139 the ID generated by mod_unique_id as error log ID for requests.
142 *) mod_cache: Make sure that we never allow a 304 Not Modified response
143 that we asked for to leak to the client should the 304 response be
144 uncacheable. PR45341 [Graham Leggett]
146 *) mod_cache: Add the cache_status hook to register the final cache
147 decision hit/miss/revalidate. Add optional support for an X-Cache
148 and/or an X-Cache-Detail header to add the cache status to the
149 response. PR48241 [Graham Leggett]
151 *) mod_authz_host: Add 'local' provider that matches connections originating
152 on the local host. PR 19938. [Stefan Fritsch]
154 *) Event MPM: Fix crash accessing pollset on worker thread when child
155 process is exiting. [Jeff Trawick]
157 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
158 pass the system library path (LD_LIBRARY_PATH or platform-specific
159 variables) along with the system PATH, by default. Both should be
160 overridden together as desired using PassEnv etc; see mod_env.
163 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
164 capture a stale backend response, perform If-Modified-Since requests
165 against the backend, and serving from the cache all 304 responses.
166 This restores pre-2.2.4 cache behavior. [William Rowe]
168 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
169 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
170 the ambiguity of the symlink test "-ltest", introduce -h or -L as
171 symlink test operators. [William Rowe]
173 *) mod_cache: Give the cache provider the opportunity to choose to cache
174 or not cache based on the buckets present in the brigade, such as the
175 presence of a FILE bucket.
178 *) mod_authz_core: Allow authz providers to check args while reading the
179 config and allow to cache parsed args. Move 'all' and 'env' authz
180 providers from mod_authz_host to mod_authz_core. Add 'method' authz
181 provider depending on the HTTP method. [Stefan Fritsch]
183 *) mod_include: Move the request_rec within mod_include to be
184 exposed within include_ctx_t. [Graham Leggett]
186 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
187 variable being echoed or set to be decoded and then encoded as separate
188 steps. PR47686 [Graham Leggett]
190 *) mod_cache: Add a discrete commit_entity() provider function within the
191 mod_cache provider interface which is called to indicate to the
192 provider that caching is complete, giving the provider the opportunity
193 to commit temporary files permanently to the cache in an atomic
194 fashion. Replace the inconsistent use of error cleanups with a formal
195 set of pool cleanups attached to a subpool, which is destroyed on error.
198 *) mod_cache: Change the signature of the store_body() provider function
199 within the mod_cache provider interface to support an "in" brigade
200 and an "out" brigade instead of just a single input brigade. This
201 gives a cache provider the option to consume only part of the brigade
202 passed to it, rather than the whole brigade as was required before.
203 This fixes an out of memory and a request timeout condition that would
204 occur when the original document was a large file. Introduce
205 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
206 the amount of data to attempt to cache at a time. [Graham Leggett]
208 *) core: Add ErrorLogFormat to allow configuring error log format, including
209 additional information that is logged once per connection or request. Add
210 error log IDs for connections and request to allow correlating error log
211 lines and the corresponding access log entry. [Stefan Fritsch]
213 *) core: Disable sendfile by default. [Stefan Fritsch]
215 *) mod_cache: Check the request to determine whether we are allowed
216 to return cached content at all, and respect a "Cache-Control:
217 no-cache" header from a client. Previously, "no-cache" would
218 behave like "max-age=0". [Graham Leggett]
220 *) mod_cache: Use a proper filter context to hold filter data instead
221 of misusing the per-request configuration. Fixes a segfault on trunk
222 when the normal handler is used. [Graham Leggett]
224 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
225 it is too long. PR 49388. [Stefan Fritsch]
227 *) vhosts: Do not allow _default_ in NameVirtualHost, or mixing *
228 and non-* ports on NameVirtualHost, or multiple NameVirtualHost
229 directives for the same address:port, or NameVirtualHost
230 directives with no matching VirtualHosts, or multiple ip-based
231 VirtualHost sections for the same address:port. These were
232 previously accepted with a warning, but the behavior was
233 undefined. [Dan Poirier]
235 *) mod_remoteip: Fix a segfault when using mod_remoteip in conjunction with
236 Allow/Deny. PR 49838. [Andrew Skalski <voltara gmail.com>]
238 *) core: DirectoryMatch can now match on the end of line character ($),
239 and sub-directories of matched directories are no longer implicitly
240 matched. PR49809 [Eric Covener]
242 *) Regexps: introduce new higher-level regexp utility including parsing
243 and executing perl-style regexp ops (e.g s/foo/bar/i) and regexp memory
246 Changes with Apache 2.3.8
248 *) suexec: Support large log files. PR 45856. [Stefan Fritsch]
250 *) core: Abort with sensible error message if no or more than one MPM is
251 loaded. [Stefan Fritsch]
253 *) mod_proxy: Rename erroronstatus to failonstatus.
254 [Daniel Ruggeri <DRuggeri primary.net>]
256 *) mod_dav_fs: Fix broken "creationdate" property.
257 Regression in version 2.3.7. [Rainer Jung]
259 Changes with Apache 2.3.7
261 *) SECURITY: CVE-2010-1452 (cve.mitre.org)
262 mod_dav, mod_cache, mod_session: Fix Handling of requests without a path
263 segment. PR: 49246 [Mark Drayton, Jeff Trawick]
265 *) mod_ldap: Properly check the result returned by apr_ldap_init. PR 46076.
268 *) mod_rewrite: Log errors if rewrite map files cannot be opened. PR 49639.
271 *) mod_proxy_http: Support the 'ping' property for backend HTTP/1.1 servers
272 via leveraging 100-Continue as the initial "request".
275 *) core/mod_authz_core: Introduce new access_checker_ex hook that enables
276 mod_authz_core to bypass authentication if access should be allowed by
277 IP address/env var/... [Stefan Fritsch]
279 *) core: Introduce note_auth_failure hook to allow modules to add support
280 for additional auth types. This makes ap_note_auth_failure() work with
281 mod_auth_digest again. PR 48807. [Stefan Fritsch]
283 *) socache modules: return APR_NOTFOUND when a lookup is not found [Nick Kew]
285 *) mod_authn_cache: new module [Nick Kew]
287 *) configure: Add reallyall option for --enable-mods-shared. [Stefan Fritsch]
289 *) Fix Windows build when using VC6. [Gregg L. Smith <lists glewis com>]
291 *) mod_rewrite: Allow to set environment variables without explicitly
292 giving a value. [Rainer Jung]
294 *) mod_rewrite: Remove superfluous EOL from rewrite logging. [Rainer Jung]
296 *) mod_include: recognise "text/html; parameters" as text/html
297 PR 49616 [Andrey Chernov <ache nagual.pp.ru>]
299 *) CGI vars: allow PATH to be set by SetEnv, consistent with LD_LIBRARY_PATH
302 *) Core: Extra robustness: don't try authz and segfault if authn
303 fails to set r->user. Log bug and return 500 instead.
306 *) HTTP protocol filter: fix handling of longer chunk extensions
307 PR 49474 [<tee.bee gmx.de>]
309 *) Update SSL cipher suite and add example for SSLHonorCipherOrder.
310 [Lars Eilebrecht, Rainer Jung]
312 *) move AddOutputFilterByType from core to mod_filter. This should
313 fix nasty side-effects that happen when content_type is set
314 more than once in processing a request, and make it fully
315 compatible with dynamic and proxied contents. [Nick Kew]
317 *) mod_log_config: Implement logging for sub second timestamps and
318 request end time. [Rainer Jung]
320 Changes with Apache 2.3.6
322 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
323 mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
324 attack when compiled against OpenSSL version 0.9.8m or later. Introduces
325 the 'SSLInsecureRenegotiation' directive to reopen this vulnerability
326 and offer unsafe legacy renegotiation with clients which do not yet
327 support the new secure renegotiation protocol, RFC 5746.
328 [Joe Orton, and with thanks to the OpenSSL Team]
330 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
331 mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
332 by rejecting any client-initiated renegotiations. Forcibly disable
333 keepalive for the connection if there is any buffered data readable. Any
334 configuration which requires renegotiation for per-directory/location
335 access control is still vulnerable, unless using OpenSSL >= 0.9.8l.
336 [Joe Orton, Ruediger Pluem, Hartmut Keil <Hartmut.Keil adnovum.ch>]
338 *) SECURITY: CVE-2010-0408 (cve.mitre.org)
339 mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent
340 when request headers indicate a request body is incoming; not a case of
341 HTTP_INTERNAL_SERVER_ERROR. [Niku Toivola <niku.toivola sulake.com>]
343 *) SECURITY: CVE-2010-0425 (cve.mitre.org)
344 mod_isapi: Do not unload an isapi .dll module until the request
345 processing is completed, avoiding orphaned callback pointers.
346 [Brett Gervasoni <brettg senseofsecurity.com>, Jeff Trawick]
348 *) core: Filter init functions are now run strictly once per request
349 before handler invocation. The init functions are no longer run
350 for connection filters. PR 49328. [Joe Orton]
352 *) core: Adjust the output filter chain correctly in an internal
353 redirect from a subrequest, preserving filters from the main
354 request as necessary. PR 17629. [Joe Orton]
356 *) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
357 Response if they so choose to do so. Previously an attempt to cache a 206
358 was arbitrarily allowed if the response contained an Expires or
359 Cache-Control header, and arbitrarily denied if both headers were missing.
362 *) core: Add microsecond timestamp fractions, process id and thread id
363 to the error log. [Rainer Jung]
365 *) configure: The "most" module set gets build by default. [Rainer Jung]
367 *) configure: Building dynamic modules (DSO) by default. [Rainer Jung]
369 *) configure: Fix broken VPATH build when using included APR.
372 *) mod_session_crypto: Fix configure problem when building
373 with APR 2 and for VPATH builds with included APR.
376 *) mod_session_crypto: API compatibility with APR 2 crypto and
377 APR Util 1.x crypto. [Rainer Jung]
379 *) ab: Fix memory leak with -v2 and SSL. PR 49383.
380 [Pavel Kankovsky <peak argo troja mff cuni cz>]
382 *) core: Add per-module and per-directory loglevel configuration.
383 Add some more trace logging.
384 mod_rewrite: Replace RewriteLog/RewriteLogLevel with trace log levels.
385 mod_ssl: Replace LogLevelDebugDump with trace log levels.
386 mod_ssl/mod_proxy*: Adjust loglevels to be less verbose at levels info
388 mod_dumpio: Replace DumpIOLogLevel with trace log levels.
391 *) mod_ldap: LDAP caching was suppressed (and ldap-status handler returns
392 title page only) when any mod_ldap directives were used in VirtualHost
393 context. [Eric Covener]
395 *) mod_disk_cache: Decline the opportunity to cache if the response is
396 a 206 Partial Content. This stops a reverse proxied partial response
397 from becoming cached, and then being served in subsequent responses.
400 *) mod_deflate: avoid the risk of forwarding data before headers are set.
401 PR 49369 [Matthew Steele <mdsteele google.com>]
403 *) mod_authnz_ldap: Ensure nested groups are checked when the
404 top-level group doesn't have any direct non-group members
405 of attributes in AuthLDAPGroupAttribute. [Eric Covener]
407 *) mod_authnz_ldap: Search or Comparison during authorization phase
408 can use the credentials from the authentication phase
409 (AuthLDAPSearchAsUSer,AuthLDAPCompareAsUser).
410 PR 48340 [Domenico Rotiroti, Eric Covener]
412 *) mod_authnz_ldap: Allow the initial DN search during authentication
413 to use the HTTP username/pass instead of an anonymous or hard-coded
414 LDAP id (AuthLDAPInitialBindAsUser, AuthLDAPInitialBindPattern).
417 *) mod_authnz_ldap: Publish requested LDAP data with an AUTHORIZE_ prefix
418 when this module is used for authorization. See AuthLDAPAuthorizePrefix.

507 *) support/rotatelogs: Support the simplest log rotation case, log
508 truncation. Useful when the log is being processed in real time
509 using a command like tail. [Graham Leggett]
511 *) support/htcacheclean: Teach it how to write a pid file (modelled on
512 httpd's writing of a pid file) so that it becomes possible to run

519 *) Introduce mod_reflector, a handler capable of reflecting POSTed
520 request bodies back within the response through the output filter
521 stack. Can be used to turn an output filter into a web service.
524 *) mod_proxy_http: Make sure that when an ErrorDocument is served
525 from a reverse proxied URL, that the subrequest respects the status
526 of the original request. This brings the behaviour of proxy_handler
527 in line with default_handler. PR 47106. [Graham Leggett]
529 *) Support wildcards in both the directory and file components of
530 the path specified by the Include directive. [Graham Leggett]

1132 filter stacks. Can collapse many small buckets into fewer larger
1133 buckets, and prevents excessively small chunks being sent over
1134 the wire. [Graham Leggett]
1136 *) mod_privileges: new module to make httpd on Solaris privileges-aware
1137 and to enable different virtualhosts to run with different
1138 privileges and Unix user/group IDs [Nick Kew]
1140 *) mod_mem_cache: this module has been removed. [William Rowe]
1142 *) authn/z: Remove mod_authn_default and mod_authz_default.
1145 *) authz: Fix handling of authz configurations, make default authz
1146 logic replicate 2.2.x authz logic, and replace <Satisfy*>, Reject,
1147 and AuthzMergeRules directives with Match, <Match*>, and AuthzMerge
1148 directives. [Chris Darroch]
1150 *) mod_authn_core: Prevent crash when provider alias created to
1151 provider which is not yet registered. [Chris Darroch]
1153 *) mod_authn_core: Add AuthType of None to support disabling
1154 authentication. [Chris Darroch]

1157 constrain their use to conform with that of other access control
1158 and authorization directives. [Chris Darroch]

1199 null value. [David Shane Holden <dpejesh apache.org>]
1201 *) core, authn/z: Determine registered authn/z providers directly in
1202 ap_setup_auth_internal(), which allows optional functions that just
1203 wrapped ap_list_provider_names() to be removed from authn/z modules.
1206 *) authn/z: Convert common provider version strings to macros.

1210 ap_location_walk(), don't look past the start of an empty string
1211 such as that created by a <Location ""> directive.

1215 subrequests to support message bodies. Make sure that safety
1216 checks within the core and within the proxy are not triggered
1217 when kept_body is present. This makes it possible to embed
1218 proxied POST requests within mod_include. [Graham Leggett]

1221 up before reading the login form. Make sure the kept body filter
1222 is correctly inserted to ensure the body can be read a second
1223 time safely should the authn be successful. [Graham Leggett,

1257 in using an HTML form, storing the credentials within mod_session.
1260 *) Add a function to the http filters that is able to parse an HTML
1261 form request with the type of application/x-www-form-urlencoded.

1277 session information within cookies on the browser. Useful for high
1278 volume sites where server bound sessions are too resource intensive.
1281 *) mod_session: Add a generic session interface to unify the different
1282 attempts at saving persistent sessions across requests.
1285 *) core, authn/z: Avoid calling access control hooks for internal requests
1286 with configurations which match those of initial request. Revert to
1287 original behaviour (call access control hooks for internal requests
1288 with URIs different from initial request) if any access control hooks or
1289 providers are not registered as permitting this optimization.
