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
and APR Utility Library (APR-util) version 1.3.11, 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.
Apache 2.2 offers numerous enhancements, improvements, and performance
boosts over the 2.0 codebase. For an overview of new features
introduced since 2.0 please see:
http://httpd.apache.org/docs/2.2/new_features_2_2.html
This release builds on and extends the Apache 2.0 API. Modules written
for Apache 2.0 will need to be recompiled in order to run with Apache
2.2, and 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.
