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 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 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:

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:
httpd 2.2 vulnerabilities - The Apache HTTP Server Project
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.
