Original Bulletin: 

- --------------------------BEGIN INCLUDED TEXT--------------------

                       Apache HTTP Server 2.2.27 Released

   The Apache Software Foundation and the Apache HTTP Server Project are
   pleased to announce the release of version 2.2.27 of the Apache HTTP
   Server ("Apache").  This version of Apache is principally a security
   and bug fix maintenance release.

   CVE-2014-0098 (cve.mitre.org)
     Segfaults with truncated cookie logging.
     mod_log_config: Prevent segfaults when logging truncated
     cookies. Clean up the cookie logging parser to recognize
     only the cookie=value pairs, not valueless cookies.

   CVE-2013-6438 (cve.mitre.org)
     mod_dav: Keep track of length of cdata properly when removing
     leading spaces. Eliminates a potential denial of service from
     specifically crafted DAV WRITE requests

   We consider the Apache HTTP Server 2.4 release to be the best version
   of Apache available, and encourage users of 2.2 and all prior
   versions to upgrade.  This 2.2 maintenance release is offered for
   those unable to upgrade at this time.  For further details, see:


   Apache HTTP Server 2.4 and 2.2.27 are available for download from:


   Please see the CHANGES_2.2 file, linked from the download page, for a
   full list of changes.  A condensed list, CHANGES_2.2.27 includes only
   those changes introduced since the prior 2.2 release.  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 1.5.0
   and APR Utility Library (APR-util) version 1.5.3, bundled with the
   tar and zip distributions.  The APR libraries libapr and libaprutil
   (and on Win32, libapriconv version 1.2.1) must all be updated to
   ensure binary compatibility and address many known security and
   platform bugs. APR version 1.5 and APR-util version 1.5 represent
   minor version upgrades from earlier httpd 2.2 source distributions.

   This release builds on and extends the Apache 2.0 API and is
   superceeded by the Apache 2.4 API.  Modules written for Apache 2.0
   or 2.4 will need to be recompiled in order to run with Apache 2.2,
   and most will require minimal or no source code changes.

   When upgrading or installing this version of Apache, please bear in
   mind that if you intend to use Apache with one of the threaded MPMs
   (other than the Prefork MPM), you must ensure that any modules you
   will be using (and the libraries they depend on) are thread-safe.
