CVE-2012-5134

TITLE

Google Chrome Used in libxml2 Service disruption in (DoS) Vulnerabilities

DESCRIPTION

Heap-based buffer underflow in the xmlParseAttValueComplex function in parser.c in libxml2 2.9.0 and earlier, as used in Google Chrome before 23.0.1271.91 and other products, allows remote attackers to cause a denial of service or possibly execute arbitrary code via crafted entities in an XML document. Google Chrome is prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code in the context of the browser, cause denial-of-service conditions, and bypass the same-origin policy; other attacks may also be possible. The issue (described by CVE-2012-5131) has been moved to BID 56752 (Apple Mac OS X Intel GPU Driver Unspecified Security Vulnerability) to better document it. Versions prior to Chrome 23.0.1271.91 are vulnerable. 6) - i386, x86_64 3. The desktop must be restarted (log out, then log back in) for this update to take effect. Bugs fixed (http://bugzilla.redhat.com/): 880466 - CVE-2012-5134 libxml2: Heap-buffer-underflow in xmlParseAttValueComplex 6.

Summary: Updated mingw32-libxml2 packages that fix several security issues are now available for Red Hat Enterprise Linux 6. This advisory also contains information about future updates for the mingw32 packages, as well as the deprecation of the packages with the release of Red Hat Enterprise Linux 6.4. The Red Hat Security Response Team has rated this update as having important 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 Optional (v. 6) - noarch Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch Red Hat Enterprise Linux Server Optional (v. 6) - noarch Red Hat Enterprise Linux Workstation Optional (v. 6) - noarch 3. Description: These packages provide the libxml2 library, a development toolbox providing the implementation of various XML standards, for users of MinGW (Minimalist GNU for Windows). IMPORTANT NOTE: The mingw32 packages in Red Hat Enterprise Linux 6 will no longer be updated proactively and will be deprecated with the release of Red Hat Enterprise Linux 6.4. These packages were provided to support other capabilities in Red Hat Enterprise Linux and were not intended for direct customer use. Customers are advised to not use these packages with immediate effect. Future updates to these packages will be at Red Hat's discretion and these packages may be removed in a future minor release. A heap-based buffer overflow flaw was found in the way libxml2 decoded entity references with long names. (CVE-2011-3919) A heap-based buffer underflow flaw was found in the way libxml2 decoded certain entities. (CVE-2012-5134) It was found that the hashing routine used by libxml2 arrays was susceptible to predictable hash collisions. Sending a specially-crafted message to an XML service could result in longer processing time, which could lead to a denial of service. To mitigate this issue, randomization has been added to the hashing function to reduce the chance of an attacker successfully causing intentional collisions. (CVE-2012-0841) Multiple flaws were found in the way libxml2 parsed certain XPath (XML Path Language) expressions. If an attacker were able to supply a specially-crafted XML file to an application using libxml2, as well as an XPath expression for that application to run against the crafted file, it could cause the application to crash. (CVE-2010-4008, CVE-2010-4494, CVE-2011-2821, CVE-2011-2834) Two heap-based buffer overflow flaws were found in the way libxml2 decoded certain XML files. (CVE-2011-0216, CVE-2011-3102) An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way libxml2 parsed certain XPath expressions. (CVE-2011-1944) An out-of-bounds memory read flaw was found in libxml2. A remote attacker could provide a specially-crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash. (CVE-2011-3905) Red Hat would like to thank the Google Security Team for reporting the CVE-2010-4008 issue. Upstream acknowledges Bui Quang Minh from Bkis as the original reporter of CVE-2010-4008. All users of mingw32-libxml2 are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 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/knowledge/articles/11258 5.
