A heap-based buffer overflow flaw was found in the way libxslt applied templates to nodes selected by certain namespaces. An attacker could use this flaw to create a malicious XSL file that, when used by an application linked against libxslt to perform an XSL transformation, could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application.
(CVE-2012-2871)

Several denial of service flaws were found in libxslt. An attacker could use these flaws to create a malicious XSL file that, when used by an application linked against libxslt to perform an XSL transformation, could cause the application to crash. (CVE-2012-2825 , CVE-2012-2870 , CVE-2011-3970)

An information leak could occur if an application using libxslt processed an untrusted XPath expression, or used a malicious XSL file to perform an XSL transformation. If combined with other flaws, this leak could possibly help an attacker bypass intended memory corruption protections. (CVE-2011-1202)

The remote VMware ESX / ESXi host is missing a security-related patch.
It is, therefore, affected by multiple vulnerabilities, including remote code execution vulnerabilities, in several components and third-party libraries :

  - Authentication Service
  - bind
  - libxml2
  - libxslt

The version of Google Chrome installed on the remote host is earlier than 17.0.963.46 and is, therefore, affected by the following vulnerabilities:

  - Clipboard monitoring after a paste action is possible.
    (CVE-2011-3953)

  - Application crashes are possible with excessive     database usage, killing an 'IndexDB' transaction,     signature checks and processing unusual certificates.
    (CVE-2011-3954, CVE-2011-3955, CVE-2011-3965,     CVE-2011-3967)

  - Sandboxed origins are not handled properly inside     extensions. (CVE-2011-3956)

  - Use-after-free errors exist related to PDF garbage     collection, stylesheet error handling, CSS handling,     SVG layout and 'mousemove' event handling.
    (CVE-2011-3957, CVE-2011-3966, CVE-2011-3968,      CVE-2011-3969, CVE-2011-3971)

  - An error exists related to bad casting and column     spans. (CVE-2011-3958)

  - A buffer overflow exists related to locale handing.
    (CVE-2011-3959)

  - Out-of-bounds read errors exist related to audio     decoding, path clipping, PDF fax imaging, 'libxslt',     and the shader translator. (CVE-2011-3960,     CVE-2011-3962, CVE-2011-3963, CVE-2011-3970,     CVE-2011-3972)

  - A race condition exists after a utility process     crashes. (CVE-2011-3961)

  - An unspecified error exists related to the URL bar     after drag and drop operations. (CVE-2011-3964)

A vulnerability has been found and corrected in libxslt :

libxslt allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors (CVE-2011-3970).

The updated packages have been patched to correct this issue.

libxslt was prone to an out-of-bounds read flaw when parsing certain patterns (CVE-2011-3970). This could have lead to a Denial of Service.

Updated libxslt packages that fix several security issues are now available for Red Hat Enterprise Linux 5 and 6.

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.

libxslt is a library for transforming XML files into other textual formats (including HTML, plain text, and other XML representations of the underlying data) using the standard XSLT stylesheet transformation mechanism.

A heap-based buffer overflow flaw was found in the way libxslt applied templates to nodes selected by certain namespaces. An attacker could use this flaw to create a malicious XSL file that, when used by an application linked against libxslt to perform an XSL transformation, could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application.

All libxslt users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. All running applications linked against libxslt must be restarted for this update to take effect.
