TITLE

libxml2 Service disruption in (DoS) Vulnerabilities

DESCRIPTION

Double free vulnerability in libxml2 2.7.8 and other versions, as used in Google Chrome before 8.0.552.215 and other products, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to XPath handling. libxml2 Is XPath Service operation disruption due to inadequate handling (DoS) There are vulnerabilities that can be in a state or are otherwise unaffected.Service disruption by a third party (DoS) May result in a condition or other unclear effects. The 'libxml2' library is prone to a memory-corruption vulnerability. An attacker can exploit this issue by tricking a victim into opening a specially crafted XML file. A successful attack can allow attacker-supplied code to run in the context of the application using the vulnerable library or can cause a denial-of-service condition. NOTE: This issue was previously discussed in BID 45170 (Google Chrome prior to 8.0.552.215 Multiple Security Vulnerabilities) but has been given its own record to better document it. It supports multiple encoding formats, XPath analysis, Well-formed and valid verification, etc. Packages for 2009.0 are provided as of the Extended Maintenance Program. The verification of md5 checksums and GPG signatures is performed automatically for you.

(CVE-2010-4008, CVE-2010-4494, CVE-2011-2821, CVE-2011-2834) Note: Red Hat does not ship any applications that use libxml2 in a way that would allow the CVE-2011-1944, CVE-2010-4008, CVE-2010-4494, CVE-2011-2821, and CVE-2011-2834 flaws to be exploited; however, third-party applications may allow XPath expressions to be passed which could trigger these flaws. This update also fixes the following bugs: * A number of patches have been applied to harden the XPath processing code in libxml2, such as fixing memory leaks, rounding errors, XPath numbers evaluations, and a potential error in encoding conversion. The desktop must be restarted (log out, then log back in) for this update to take effect. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201110-26 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: libxml2: Multiple vulnerabilities Date: October 26, 2011 Bugs: #345555, #370715, #386985 ID: 201110-26 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities were found in libxml2 which could lead to execution of arbitrary code or a Denial of Service.

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. 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 or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2011-3919) A heap-based buffer underflow flaw was found in the way libxml2 decoded certain entities. 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 or, potentially, execute arbitrary code with the privileges of the user running the application. (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. 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 or, potentially, execute arbitrary code with the privileges of the user running the application. (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. 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 or, possibly, execute arbitrary code. (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.
