Apache HTTP Server 2.2.18 Released

                       Apache HTTP Server 2.2.18 Released

   The Apache Software Foundation and the Apache HTTP Server Project are
   pleased to announce the release of version 2.2.18 of the Apache HTTP
   Server ("Apache").  This version of Apache is principally a bug fix
   release, and a security fix release of the APR 1.4.4 dependency;

     * SECURITY: CVE-2011-0419 (cve.mitre.org)
       apr_fnmatch flaw leads to mod_autoindex remote DoS
       Where mod_autoindex is enabled, and a directory indexed by
       mod_autoindex contained files with sufficiently long names,
       a carefully crafted request may cause excessive CPU usage
       Upgrading to APR 1.4.4, or setting the 'IgnoreClient' option
       of the 'IndexOptions' directive circumvents this risk.

   We consider this release to be the best version of Apache available, and
   encourage users of all prior versions to upgrade.

   Apache HTTP Server 2.2.18 is available for download from:

     http://httpd.apache.org/download.cgi

   Please see the CHANGES_2.2 file, linked from the download page, for a
   full list of changes.  A condensed list, CHANGES_2.2.18 provides the
   complete list of changes since 2.2.17.  A summary of all of the security
   vulnerabilities addressed in this and earlier releases is available:

   This release includes the Apache Portable Runtime (APR) version 1.4.4

Regressions in httpd 2.2.18, apr 1.4.4, and apr-util 1.3.11


New releases are in progress for each of these projects and are
expected to be available in the coming days.  The upcoming httpd
2.2.19 will bundle new releases of apr and apr-util which correct
the regressions described below.  An announcement of these releases
will be broadcast.

Note: httpd 2.2.18 bundles apr 1.4.4 and apr-util 1.3.11.

Summary of regressions:

httpd 2.2.18: The ap_unescape_url_keep2f() function signature was changed.
This breaks binary compatibility of a number of third-party modules. In
addition, a regression in apr 1.4.4 (see below) could cause httpd to hang.

apr 1.4.4: A fix in apr 1.4.4 apr_fnmatch() to address CVE-2011-0419
introduced a new vulnerability.  A patch is attached and should be used
if httpd workers enter a hung state (100% cpu utilization) after updating
to httpd 2.2.18 or apr-util 1.4.4, or if hangs are seen in other apr
applications which use apr_fnmatch().

apr-util 1.3.11: A fix to LDAP support in apr-util 1.3.11 could cause
crashes with httpd's mod_authnz_ldap in some situations.

Apache HTTP Server 2.2.19 Released

                       Apache HTTP Server 2.2.19 Released

   The Apache Software Foundation and the Apache HTTP Server Project are
   pleased to announce the release of version 2.2.19 of the Apache HTTP
   Server ("Apache").  This version of Apache is principally a bug fix
   release, correcting regressions in the httpd 2.2.18 package; the use
   of that previous 2.2.18 package is discouraged due to these flaws:

     * SECURITY: CVE-2011-1928 (cve.mitre.org)
       A fix in bundled APR 1.4.4 apr_fnmatch() to address CVE-2011-0419
       introduced a new vulnerability.  httpd workers enter a hung state
       (100% cpu utilization) after updating to APR 1.4.4.  Upgrading to
       APR 1.4.5 bundled with the httpd 2.2.19 package, or using APR 1.4.3
       or prior with the 'IgnoreClient' option of the 'IndexOptions'
       directive will circumvent both issues.

     * httpd 2.2.18: The ap_unescape_url_keep2f() function signature was
       inadvertantly changed. This breaks binary compatibility of a number
       of third-party modules.  This httpd-2.2.19 package restores the
       function signature provided by 2.2.17 and prior.

   We consider this release to be the best version of Apache available, and
   encourage users of all prior versions to upgrade.

   Apache HTTP Server 2.2.19 is available for download from:

     http://httpd.apache.org/download.cgi
