CVE-2011-3607

TITLE

Apache HTTP Server ‘ ap_pregsub() ‘function local privilege escalation 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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: httpd security update Advisory ID: RHSA-2012:0128-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0128.html Issue date: 2012-02-13 CVE Names: CVE-2011-3607 CVE-2011-3639 CVE-2011-4317 CVE-2012-0031 CVE-2012-0053 ===================================================================== 1. Summary: Updated httpd packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64 3. It was discovered that the fix for CVE-2011-3368 (released via RHSA-2011:1391) did not completely address the problem. An attacker could bypass the fix and make a reverse proxy connect to an arbitrary server not directly accessible to the attacker by sending an HTTP version 0.9 request, or by using a specially-crafted URI. (CVE-2011-3639, CVE-2011-4317) The httpd server included the full HTTP header line in the default error page generated when receiving an excessively long or malformed header. Malicious JavaScript running in the server's domain context could use this flaw to gain access to httpOnly cookies. (CVE-2012-0053) An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way httpd performed substitutions in regular expressions. An attacker able to set certain httpd settings, such as a user permitted to override the httpd configuration for a specific directory using a ".htaccess" file, could use this flaw to crash the httpd child process or, possibly, execute arbitrary code with the privileges of the "apache" user. (CVE-2011-3607) A flaw was found in the way httpd handled child process status information. A malicious program running with httpd child process privileges (such as a PHP or CGI script) could use this flaw to cause the parent httpd process to crash during httpd service shutdown. (CVE-2012-0031) All httpd users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon will be restarted automatically. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259 5.

The could allow the attacker to access internal servers that are not otherwise accessible from the outside. The three CVE ids denote slightly different variants of the same issue. Note that, even with this issue fixed, it is the responsibility of the administrator to ensure that the regular expression replacement pattern for the target URI does not allow a client to append arbitrary strings to the host or port parts of the target URI. This is a violation of the privilege separation between the apache2 processes and could potentially be used to worsen the impact of other vulnerabilities. This could allow a remote attacker using cross site scripting to steal authentication cookies. For the oldstable distribution (lenny), these problems have been fixed in version apache2 2.2.9-10+lenny12. For the stable distribution (squeeze), these problems have been fixed in version apache2 2.2.16-6+squeeze6 For the testing distribution (wheezy), these problems will be fixed in version 2.2.22-1. For the unstable distribution (sid), these problems have been fixed in version 2.2.22-1. We recommend that you upgrade your apache2 packages. The new version number for the oldstable distribution is 2.2.6-02-1+lenny7. In the stable distribution, apache2-mpm-itk has the same version number as apache2. Please review the CVE identifiers referenced below for details. Workaround ========== There is no known workaround at this time.

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-2012-0053 (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.

An attacker having write access to a .htaccess file may exploit this to possibly execute arbitrary code. (CVE-2011-3607) Prutha Parikh discovered that the mod_proxy module did not properly interact with the RewriteRule and ProxyPassMatch pattern matches in the configuration of a reverse proxy. (CVE-2011-4317) Rainer Canavan discovered that the mod_log_config module incorrectly handled a certain format string when used with a threaded MPM. A local attacker could exploit this to to cause a denial of service. (CVE-2012-0053) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: apache2.2-common 2.2.20-1ubuntu1.2 Ubuntu 11.04: apache2.2-common 2.2.17-1ubuntu1.5 Ubuntu 10.10: apache2.2-common 2.2.16-1ubuntu3.5 Ubuntu 10.04 LTS: apache2.2-common 2.2.14-5ubuntu8.8 Ubuntu 8.04 LTS: apache2.2-common 2.2.8-1ubuntu0.23 In general, a standard system update will make all the necessary changes. It was discovered that the Apache HTTP Server did not properly validate the request URI for proxied requests. (CVE-2011-3368) It was discovered that mod_proxy_ajp incorrectly returned an "Internal Server Error" response when processing certain malformed HTTP requests, which caused the back-end server to be marked as failed in configurations where mod_proxy was used in load balancer mode. A remote attacker could cause mod_proxy to not send requests to back-end AJP (Apache JServ Protocol) servers for the retry timeout period or until all back-end servers were marked as failed. (CVE-2011-3607) A NULL pointer dereference flaw was found in the httpd mod_log_config module. This update also fixes the following bug: * The fix for CVE-2011-3192 provided by the RHSA-2011:1329 update introduced a regression in the way httpd handled certain Range HTTP header values. This update corrects this regression
