TITLE

Google Chrome Libxml2 Double release vulnerability

DESCRIPTION

Double free vulnerability in libxml2, as used in Google Chrome before 14.0.835.163, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to XPath handling. Google Chrome is prone to multiple vulnerabilities. Attackers can exploit these issues to execute arbitrary code in the context of the browser, cause denial-of-service conditions, perform spoofing attacks, and bypass the same-origin policy; other attacks may also be possible. Versions prior to Chrome 14.0.835.163 are vulnerable. Google Chrome is a web browser developed by Google (Google). -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 APPLE-SA-2012-05-09-1 OS X Lion v10.7.4 and Security Update 2012-002 OS X Lion v10.7.4 and Security Update 2012-002 is now available and addresses the following: Login Window Available for: OS X Lion v10.7.3, OS X Lion Server v10.7.3 Impact: Remote admins and persons with physical access to the system may obtain account information Description: An issue existed in the handling of network account logins.

Beginning with AirPort Base Station and Time Capsule Firmware Update 7.6, Time Capsules and Base Stations support a secure SRP-based authentication mechanism over AFP. However, Time Machine did not require that the SRP-based authentication mechanism was used for subsequent backup operations, even if Time Machine was initially configured or had ever contacted a Time Capsule or Base Station that supported it. An attacker who is able to spoof the remote volume could gain access to user's Time Capsule credentials, although not backup data, sent by the user's system. This issue is addressed by requiring use of the SRP-based authentication mechanism if the backup destination has ever supported it.

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.
