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:
http://www.apache.org/dist/httpd/Announcement2.4.txt
Apache HTTP Server 2.4 and 2.2.27 are 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_2.2.27 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:
http://httpd.apache.org/security/vulnerabilities_22.html
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.
