-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2014.1509 Apache HTTP Server 2.2.29 Released 4 September 2014 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Apache HTTP Server Publisher: The Apache Software Foundation and Apache HTTP Server Project Operating System: UNIX variants (UNIX, Linux, OSX) Windows Impact/Access: Execute Arbitrary Code/Commands -- Remote/Unauthenticated Denial of Service -- Remote/Unauthenticated Reduced Security -- Remote/Unauthenticated Resolution: Patch/Upgrade CVE Names: CVE-2014-0231 CVE-2014-0226 CVE-2014-0118 CVE-2013-5704 Original Bulletin: http://www.apache.org/dist/httpd/Announcement2.4.txt - --------------------------BEGIN INCLUDED TEXT-------------------- Apache HTTP Server 2.2.29 Released The Apache Software Foundation and the Apache HTTP Server Project are pleased to announce the release of version 2.2.29 of the Apache HTTP Server ("Apache"). (Note that 2.2.28 was not released). This version of Apache is principally a security and bug fix maintenance release, and addresses these specific security defects as well as other fixes; CVE-2014-0118 (cve.mitre.org) mod_deflate: The DEFLATE input filter (inflates request bodies) now limits the length and compression ratio of inflated request bodies to avoid denial of sevice via highly compressed bodies. See directives DeflateInflateLimitRequestBody, DeflateInflateRatioLimit, and DeflateInflateRatioBurst. CVE-2014-0231 (cve.mitre.org) mod_cgid: Fix a denial of service against CGI scripts that do not consume stdin that could lead to lingering HTTPD child processes filling up the scoreboard and eventually hanging the server. By default, the client I/O timeout (Timeout directive) now applies to communication with scripts. The CGIDScriptTimeout directive can be used to set a different timeout for communication with scripts. CVE-2014-0226 (cve.mitre.org) Fix a race condition in scoreboard handling, which could lead to a heap buffer overflow. CVE-2013-5704 (cve.mitre.org) HTTP trailers could be used to replace HTTP headers late during request processing, potentially undoing or otherwise confusing modules that examined or modified request headers earlier. Adds "MergeTrailers" directive to restore this legacy behavior. 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 2.2.29 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_2.2.29 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 1.5.1 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. - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
