On 2012年02月2日, in soft, by netoearth
Apache HTTP Server version 2.2.22 has been released. It addresses a wide array of vulnerabilities ranging from denial of service to integer overflow issues. Apache HTTP Server 2.2.22 Released

 The Apache Software Foundation and the Apache HTTP Server Project are
 pleased to announce the release of version 2.2.22 of the Apache HTTP
 Server ("Apache"). This version of Apache is principally a security
 and bug fix release, including the following significant security fixes:

 * SECURITY: CVE-2011-3368 (cve.mitre.org)
 Reject requests where the request-URI does not match the HTTP
 specification, preventing unexpected expansion of target URLs in
 some reverse proxy configurations.

 * SECURITY: CVE-2011-3607 (cve.mitre.org)
 Fix integer overflow in ap_pregsub() which, when the mod_setenvif module
 is enabled, could allow local users to gain privileges via a .htaccess

 * SECURITY: CVE-2011-4317 (cve.mitre.org)
 Resolve additional cases of URL rewriting with ProxyPassMatch or
 RewriteRule, where particular request-URIs could result in undesired
 backend network exposure in some configurations.

 * SECURITY: CVE-2012-0021 (cve.mitre.org)
 mod_log_config: Fix segfault (crash) when the '%{cookiename}C' log format
 string is in use and a client sends a nameless, valueless cookie, causing
 a denial of service. The issue existed since version 2.2.17.

 * SECURITY: CVE-2012-0031 (cve.mitre.org)
 Fix scoreboard issue which could allow an unprivileged child process
 could cause the parent to crash at shutdown rather than terminate

 * SECURITY: CVE-2012-0053 (cve.mitre.org)
 Fixed an issue in error responses that could expose "httpOnly" cookies
 when no custom ErrorDocument is specified for status code 400.

 The Apache HTTP Project thanks halfdog, Context Information Security Ltd,
 Prutha Parikh of Qualys, and Norman Hippert for bringing these issues to
 the attention of the security team.

 We consider this release to be the best version of Apache available, and
 encourage users of all prior versions to upgrade.

 Apache HTTP Server 2.2.22 is 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_2.2.22 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 1.4.5
 and APR Utility Library (APR-util) version 1.4.2, 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.

 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:


 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.
