Changes with Apache 2.2.6 
  *) SECURITY: CVE-2007-3847 (cve.mitre.org) 
     mod_proxy: Prevent reading past the end of a buffer when parsing 
     date-related headers.  PR 41144. 
     [Davi Arnaut, Nick Kew] 
  *) SECURITY: CVE-2007-1863 (cve.mitre.org) 
     mod_cache: Prevent a segmentation fault if attributes are listed in a  
     Cache-Control header without any value.  
     [Niklas Edmundsson <nikke acc.umu.se>] 
  *) SECURITY: CVE-2007-3304 (cve.mitre.org) 
     prefork, worker, event MPMs: Ensure that the parent process cannot 
     be forced to kill processes outside its process group.  
     [Joe Orton, Jim Jagielski] 
  *) SECURITY: CVE-2006-5752 (cve.mitre.org) 
     mod_status: Fix a possible XSS attack against a site with a public 
     server-status page and ExtendedStatus enabled, for browsers which 
     perform charset "detection".  Reported by Stefan Esser.  [Joe Orton] 
  *) SECURITY: CVE-2007-1862 (cve.mitre.org) 
     mod_mem_cache: Copy headers into longer lived storage; header names and 
     values could previously point to cleaned up storage.  PR 41551. 
     [Davi Arnaut <davi haxent.com.br>] 
  *) mod_info: mod_info outputs invalid XHTML 1.0 transitional. 
     PR 42847 [Rici Lake <rici ricilake.net>] 
  *) mod_ssl: Fix spurious hostname mismatch warning for valid 
     wildcard certificates.  PR 37911.  [Nick Burch <nick torchbox.com>] 
  *) mod_mem_cache: Increase the minimum and default value for 
     MCacheMinObjectSize from 0 to 1, as a MCacheMinObjectSize of 0 does not 
     make sense and leads to a division by zero.  PR 40576. 
     [Xuekun Hu <xuekun.hu gmail.com>] 
  *) mod_cache: Remove expired content from cache that cannot be revalidated. 
     PR 30370. [Ruediger Pluem] 
  *) mod_proxy_http: accept proxy-sendchunked/proxy-sendchunks as synonymous. 
     PR 43183 [Brian Rectanus <Brian.Rectanus breach.com>, Vincent Bray]

     worker and URL when searching for the best fitting worker for a given URL. 
     PR 40910 [Ruediger Pluem] 
  *) mod_proxy: Improve network performance by setting APR_TCP_NODELAY 
     (disable Nagle algorithm) on sockets if implemented.

  *) core: Do not replace a Date header set by a proxied backend server. 
     PR 40232 [Ruediger Pluem]

  *) mod_proxy_http: Don't try to read body of a HEAD request before 
     responding.  PR 41644 [Stuart Children <stuart terminus.co.uk>] 
  *) mod_authnz_ldap: Don't return HTTP_UNAUTHORIZED during authorization when 
     LDAP authentication is configured but we haven't seen any  
     'Require ldap-*' directives, allowing authorization to be passed to lower  
     level modules (e.g. Require valid-user)  
     PR 43281 [Eric Covener] 
  *) mod_proxy: don't URLencode tilde in path component 
     PR 38448 [Stijn Hoop <stijn sandcat.nl>] 
  *) proxy/ajp_header.c: Fixed header token string comparisons 
     Matching of header tokens failed to include the trailing NIL byte 
     and could misinterpret a longer header token for a shorter. 
     Additionally, a "Content-Type" comparison was made case insensitive. 
     [Martin Kraemer] 
  *) proxy/ajp_header.c: Backport of an AJP protocol fix for EBCDIC 
     On EBCDIC machines, the status_line string was incorrectly converted 
     twice. [Jean-Frederic Clere, Martin Kraemer] 
  *) mod_dumpio: Fix for correct dumping of traffic on EBCDIC hosts 
     Data had been incorrectly converted twice, resulting in 
     garbled log output. [Martin Kraemer] 
  *) mod_autoindex: Add in Type and Charset options to IndexOptions 
     directive. This allows the admin to explicitly set the  
     content-type and charset of the generated page and is therefore 
     a viable workaround for buggy browsers affected by CVE-2007-4465 
     (cve.mitre.org). [Jim Jagielski] 
  *) log core: ensure we use a special pool for stderr logging, so that 
     the stderr channel remains valid from the time plog is destroyed, 
     until the time the open_logs hook is called again.  [William Rowe] 
  *) mod_negotiation: preserve Query String in resolving a type map 
     PR 33112 [Jørgen Thomsen <apache jth.net>, Nick Kew] 
  *) mod_ssl: Version reporting update; displays 'compiled against' 
     Apache and build-time SSL Library versions at loglevel [info], 
     while reporting the run-time SSL Library version in the server 
     info tags.  Helps to identify a mod_ssl built against one flavor 
     of OpenSSL but running against another (also adds SSL-C version 
     number reporting.)  [William Rowe] 
  *) mime.types: Many updates to sync with IANA registry and common 
     unregistered types that the owners refuse to register.  Admins 
     are encouraged to update their installed mime.types file. 
     PR: 35550, 37798, 39317, 31483 [Roy T. Fielding] 
  *) mod_expires: don't crash on bad configuration data 
     PR 43213 [Julien Perez <julien.perez epsylonia.net>] 
  *) mod_dbd: Introduce configuration groups to allow inheritance by virtual 
     hosts of database configurations from the main server.  Determine the 
     minimal set of distinct configurations and share connection pools 
     whenever possible.  Allow virtual hosts to override inherited SQL 
     statements.  PR 41302.  [Chris Darroch] 
  *) mod_dbd: Create memory sub-pools for each DB connection and close 
     DB connections in a pool cleanup function.  Ensure prepared statements 
     are destroyed before DB connection is closed.  When using reslists, 
     prevent segfaults when child processes exit, and stop memory leakage 
     of ap_dbd_t structures.  Avoid use of global s->process->pool, which 
     isn't destroyed by exiting child processes in most multi-process MPMs. 
     PR 39985.  [Chris Darroch, Nick Kew] 
  *) mod_dbd: Handle error conditions in dbd_construct() properly. 
     Simplify ap_dbd_open() and use correct arguments to apr_dbd_error() 
     when non-threaded.  Register correct cleanup data in non-threaded 
     ap_dbd_acquire() and ap_dbd_cacquire().  Clean up configuration data 
     and merge function.  Use ap_log_error() wherever possible. 
     [Chris Darroch, Nick Kew] 
  *) mod_dbd: Stash DBD connections in request_config of initial request 
     only, or else sub-requests and internal redirections may cause 
     entire DBD pool to be stashed in a single HTTP request.  [Chris Darroch] 
  *) main core: Emit errors during the initial apr_app_initialize() 
     or apr_pool_create() (when apr-based error reporting is not ready). 
     [William Rowe, Jeff Trawick] 
  *) log core: fix the new piped logger case where we couldn't connect  
     the replacement stderr logger's stderr to the NULL stdout stream.   
     Continue in this case, since the previous alternative of no error  
     logging at all (/dev/null) is far worse. [William Rowe] 
  *) mpm_winnt: Prevent the parent-child pipe from leaking into other 
     spawned processes, and ensure we have a /Device/null handle for 
     stdout when running as-a-service.  [William Rowe] 
  *) mod_ldap: Avoid possible crashes, hangs, and busy loops due to 
     improper merging of the cache lock in vhost config 
     PR 43164 [Eric Covener] 
  *) ApacheMonitor: Fix Windows Vista detection. [Mladen Turk] 
  *) mod_deflate: fix protocol handling in deflate input filter 
     PR 23287 [Nick Kew] 
  *) mime.types: add Registered Javascript/ECMAScript MIME types (RFC4329) 
     PR 40299 [Dave Hodder <dmh dmh.org.uk>] 
  *) mod_filter: fix integer comparisons in dispatch rules 
     PR 41835 [Nick Kew] 
  *) mod_filter: fix merging of ! and = in FilterChain 
     PR 42186 [Issac Goldstand <margol beamartyr.net>] 
  *) mod_deflate: don't try to process metadata buckets as data.  what should 
     have been a 413 error was logged as a 500 and a blank screen appeared 
     at the browser. 
     [Greg Ames, Ruediger Pluem] 
  *) mod_cgi, mod_cgid: Fix use of CGI scripts as ErrorDocuments. 
     PR 39710.  [Paul Querna, Ruediger Pluem] 
  *) mod_proxy: Allow to use different values for sessionid 
     in url encoded id and cookies. PR 41897. [Jean-Frederic Clere] 
  *) mod_proxy: Fix the 503 returned when session route does 
     not match any of the balancer members. [Mladen Turk] 
  *) mod_proxy: Added ProxyPassMatch directive, which is similar 
     to ProxyPass but takes a regex local path prefix. [Jim Jagielski] 
  *) mod_cache: Do not set Date or Expires when they are missing from 
     the original response or are invalid.  [Justin Erenkrantz] 
  *) mod_cache: Correctly handle HEAD requests on expired cache content. 
     PR 41230.  [Niklas Edmundsson <nikke acc.umu.se>] 
  *) mod_cache: Let Cache-Control max-age set the expiration of the cached 
     representation if Expires is not set.  [Justin Erenkrantz]

     Cache-Control max-age is explicitly specified.  [Justin Erenkrantz] 
  *) mod_disk_cache: Allow Vary'd responses to be refreshed properly.

     been applied to this cached entity before saving it to the cache are not 
     applied again. PR 40090.  [Ruediger Pluem] 
  *) mod_cache: Correctly cache objects whose URL query string has been 
     modified by mod_rewrite. PR 40805.  [Ruediger Pluem] 
  *) HTTP proxy ProxyErrorOverride: Leave 1xx and 3xx responses alone.  Only 
     processing of error responses (4xx, 5xx) will be altered. PR 39245. 
     [Jeff Trawick, Bart van der Schans <schans hippo.nl>] 
  *) htdbm: Enable crypt support on platforms with crypt() but not 
     <crypt.h>, such as z/OS.  [David Jones <oscaremma gmail.com>] 
  *) mod_ssl: initialize thread locks before initializing the hardware 
     acceleration library, so the latter can make use of the former. 
     PR 20951.  [<adunn at ncipher.com>]

     in presence of -H command-line overrides. PR 31268, 26554. 
     [Arvind Srinivasan <arvind.srinivasan  sun.com>]

     signed format code in its reports. PR 42070. 
     [Takashi Sato <serai  lans-tv.com>] 
  *) mod_ldap: Remove the hardcoded size limit parameter for 
     ldap_search_ext_s and replace it with an APR_ defined 
     value that is set according to the LDAP SDK being used. 
     [David Jones <oscaremma gmail com>]

     [Rob Baily <rbaily servicebench com>] 
  *) mod_mem_cache: Convert mod_mem_cache to use APR memory pool functions 
     by creating a root pool for object persistence across requests. This 
     also eliminates the need for custom serialization code. 
     [Davi Arnaut <davi haxent.com.br>] 
  *) mod_authnz_ldap: Add an AuthLDAPRemoteUserAttribute directive. If 
     set, REMOTE_USER will be set to this attribute, rather than the 
     username supplied by the user. Useful for example when you want users 
     to log in using an email address, but need to supply a userid instead 
     to the backend.  [Graham Leggett]

     from input filters as HTTP return value from the handler.

     of listen sockets in some configurations with multiple generic Listen 
     directives.  [Jeff Trawick] 
  *) mod_headers: Support regexp-based editing of HTTP headers.  [Nick Kew] 
  *) mod_proxy: Add explicit flushing feature. When Servlet container sends AJP 
     body message with size 0, this means that Servlet container has asked for 
     an explicit flush. Create flush bucket in that case. This feature has been 
     added to the recent Tomcat versions without breaking the AJP protocol. 
     [Mladen Turk] 
  *) mod_proxy_balancer: Set the new environment variable BALANCER_ROUTE_CHANGED 
     if a worker with a route different from the one supplied by the client 
     had been chosen or if the client supplied no routing information for 
     a balancer with sticky sessions.  [Ruediger Pluem]

     [Ruediger Pluem, Tomokazu Harada <harada sysrdc.ns-sol.co.jp>] 
  *) mod_proxy_ajp: Added cping/cpong support for the AJP protocol. 
     A new worker directive ping=timeout will cause CPING packet 
     to be send expecting CPONG packet within defined timeout.   
     In case the backend is too busy this will fail instead 
     sending the full header.  [Mladen Turk] 
  *) mod_disk_cache: Make sure that only positive integers are accepted 
     for the CacheMaxFileSize and CacheMinFileSize parameters in the 
     config file. PR39380.  [Niklas Edmundsson <nikke acc.umu.se>] 
  *) mod_cache: From RFC3986 (section 6.2.3.) if a URI contains an 
     authority component and an empty path, the empty path is to be equivalent 
     to "/". It explicitly cites the following four URIs as equivalents: 
     [Davi Arnaut <davi haxent.com.br>] 
  *) mod_cache: Don't cache requests with a expires date in the past; 
     otherwise mod_cache will always try to cache the URL. This bug 
     might lead to numerous rename() errors on win32 if the URL was 
     previously cached. [Davi Arnaut <davi haxent.com.br>] 
  *) core: Deal with the widespread use of apr_status_t return values 
     as HTTP status codes, as documented in PR#31759 (a bug shared by

  *) mod_proxy: Fix a request corruption problem and a buffering problem 
     which sometimes prevented proxy-sendchunks from working.

  *) Log the client IP address when an error occurs disabling nagle on a 
     connection, but log at a severity of debug since this error

     The module is now called authnz_ldap and has been moved out of 
     the modules/experimental area and into modules/aaa with the other 
     auth modules.  Both the authn_ldap provider and the authz_ldap 
     handler are contained within the authnz_ldap module.  The

     [Mladen Turk] 
  *) Added proxy_ajp.c module for proxy support to ajp:// backends. 
     [Jean Frederic Clere] 
  *) Fixes the build of proxy on Windows. Since the proxy_module is declared
