Apache HTTP Server 2.2.23 Released
The Apache Software Foundation and the Apache HTTP Server Project are
pleased to announce the release of version 2.2.23 of the Apache HTTP
Server ("Apache"). This version of Apache is principally a security
and bug fix maintenance release, including the following significant
security fixes:
* SECURITY: CVE-2012-0883 (cve.mitre.org)
envvars: Fix insecure handling of LD_LIBRARY_PATH that could lead to the
current working directory to be searched for DSOs.
* SECURITY: CVE-2012-2687 (cve.mitre.org)
mod_negotiation: Escape filenames in variant list to prevent a
possible XSS for a site where untrusted users can upload files to
a location with MultiViews enabled.
We consider the Apache HTTP Server 2.4.3 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 do so at this time. For further details, see
http://www.apache.org/dist/httpd/Announcement2.4.txt
Apache HTTP Server 2.4.3 and 2.2.23 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_2.2.23 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 1.4.6
and APR Utility Library (APR-util) version 1.4.1, 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-util version 1.4 represents a minor version upgrade from earlier
httpd source distributions, which previously included version 1.3.
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.
