TITLE

Apache HTTP Server Integer overflow vulnerability

DESCRIPTION

Integer overflow in the ap_pregsub function in server/util.c in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif module is enabled, allows local users to gain privileges via a .htaccess file with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request header, leading to a heap-based buffer overflow. Apache HTTP Server is prone to a local privilege-escalation vulnerability because of an integer-overflow error. Local attackers can exploit this issue to run arbitrary code with elevated privileges (with the privileges of the Apache webserver process). Failed exploit attempts may crash the affected application, denying service to legitimate users. Note: To trigger this issue, 'mod_setenvif' must be enabled and the attacker should be able to place a malicious '.htaccess' file on the affected webserver. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/apache < 2.2.22-r1 >= 2.2.22-r1 Description =========== Multiple vulnerabilities have been discovered in Apache HTTP Server. Please review the CVE identifiers referenced below for details. Impact ====== A remote attacker might obtain sensitive information, gain privileges, send requests to unintended servers behind proxies, bypass certain security restrictions, obtain the values of HTTPOnly cookies, or cause a Denial of Service in various ways. A local attacker could gain escalated privileges. Workaround ========== There is no known workaround at this time. Resolution ========== All Apache HTTP Server users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/apache-2.2.22-r1" References ========== [ 1 ] CVE-2010-0408 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-0408 [ 2 ] CVE-2010-0434 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-0434 [ 3 ] CVE-2010-1452 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-1452 [ 4 ] CVE-2010-2791 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-2791 [ 5 ] CVE-2011-3192 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-3192 [ 6 ] CVE-2011-3348 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-3348 [ 7 ] CVE-2011-3368 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-3368 [ 8 ] CVE-2011-3607 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-3607 [ 9 ] CVE-2011-4317 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-4317 [ 10 ] CVE-2012-0021 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0021 [ 11 ] CVE-2012-0031 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0031 [ 12 ] CVE-2012-0053 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0053 [ 13 ] CVE-2012-0883 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0883 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201206-25.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.

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-2011-4317 (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 cleanly. * 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: 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_2.2.22 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: http://httpd.apache.org/security/vulnerabilities_22.html 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: 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. http://svn.apache.org/repos/asf/httpd/httpd/branches/2.2.x/VERSIONING 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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 SUPPORT COMMUNICATION - SECURITY BULLETIN Document ID: c03231301 Version: 1 HPSBMU02748 SSRT100772 rev.1 - HP OpenView Network Node Manager (OV NNM) Running Apache HTTP Server, Remote Unauthorized Disclosure of Information, Unauthorized Modification, Denial of Service (DoS) NOTICE: The information in this Security Bulletin should be acted upon as soon as possible.
