Google V8 before 3.13.7.5, as used in Google Chrome before 23.0.1271.64, does not properly perform write operations, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

The remote host is affected by the vulnerability described in GLSA-201309-16 (Chromium, V8: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Chromium and V8. Please       review the CVE identifiers and release notes referenced below for       details.
  Impact :

    A context-dependent attacker could entice a user to open a specially       crafted website or JavaScript program using Chromium or V8, possibly       resulting in the execution of arbitrary code with the privileges of the       process or a Denial of Service condition. Furthermore, a remote attacker       may be able to bypass security restrictions or have other, unspecified,       impact.
  Workaround :

    There is no known workaround at this time.

Update to 3.13.7.5. Fixes CVE-2012-5120 CVE-2012-5128 and gets d8 working properly again.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Versions of Google Chrome earlier than 23.0.1271.64 are potentially affected by the following vulnerabilities :

  - Use-after-free errors exist related to SVG filter handling, video layout, extension tab handling and plug-in placeholder handling. (CVE-2012-5116, CVE-2012-5121, CVE-2012-5125, CVE-2012-5126)

  - An error exists related to inappropriate SVG subresource loading in the 'img' context. (CVE-2012-5117)

  - A race condition exists related to 'Pepper' buffer handling. (CVE-2012-5119)

  - A bad cast error exists related to input handling. (CVE-2012-5122)

  - Out-of-bounds reads exist related to Skia. (CVE-2012-5123)

  - A memory corruption error exists related to texture handling. (CVE-2012-5124)

  - An integer overflow error exists related to 'WebP' handling. This error can lead to out-of-bounds reads. (CVE-2012-5127)

  - An improper write error exists related to the 'v8' JavaScript engine. (CVE-2012-5128)

Successful exploitation of any of these issues could lead to an application crash or even allow arbitrary code execution, subject to the user's privileges.

The version of Google Chrome installed on the remote host is earlier than 23.0.1271.64 and is, therefore, affected by the following vulnerabilities :

  - Use-after-free errors exist related to SVG filter     handling, video layout, extension tab handling and     plug-in placeholder handling. (CVE-2012-5116,     CVE-2012-5121, CVE-2012-5125, CVE-2012-5126)

  - An error exists related to inappropriate SVG     subresource loading in the 'img' context.
    (CVE-2012-5117)

  - A race condition exists related to 'Pepper' buffer     handling. (CVE-2012-5119)

  - A bad cast error exists related to input handling.
    (CVE-2012-5122)

  - Out-of-bounds reads exist related to Skia.
    (CVE-2012-5123)

  - A memory corruption error exists related to texture     handling. (CVE-2012-5124)

  - An integer overflow error exists related to 'WebP'     handling. This error can lead to out-of-bounds reads.
    (CVE-2012-5127)

  - An improper write error exists related to the 'v8'     JavaScript engine. (CVE-2012-5128)

Successful exploitation of any of these issues could lead to an application crash or even allow arbitrary code execution, subject to the user's privileges.
