Google Chrome before 23.0.1271.97, and Libav 0.7.x before 0.7.7 and 0.8.x before 0.8.5, do not properly perform AAC decoding, which allows remote attackers to cause a denial of service (stack memory corruption) or possibly have unspecified other impact via vectors related to "an off-by-one overwrite when switching to LTP profile from MAIN."

The remote host is affected by the vulnerability described in GLSA-201406-28 (Libav: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Libav. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to open a specially crafted media       file in an application linked against Libav, possibly resulting in       execution of arbitrary code with the privileges of the application or a       Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

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.

Bundled version of libav in gstreamer-ffmpeg contains a number of vulnerabilities.

It was discovered that Libav incorrectly handled certain malformed media files. If a user were tricked into opening a crafted media file, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program.

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

The version of Google Chrome installed on the remote host is earlier than 23.0.1271.97 and is, therefore, affected by the following vulnerabilities :

  - Use-after-free errors exist related to visibility events     and the URL loader. (CVE-2012-5139, CVE-2012-5140)

  - An unspecified error exists related to instantiation     of the 'Chromoting' client plugin. (CVE-2012-5141)

  - An unspecified error exists related to history     navigation that can lead to application crashes.
    (CVE-2012-5142)

  - An integer overflow error exists related to the 'PPAPI'     image buffers. (CVE-2012-5143)

  - A stack corruption error exists related to 'AAC'     decoding. (CVE-2012-5144)

  - The bundled version of Adobe Flash Player contains     flaws that can lead to arbitrary code execution.
    (CVE-2012-5676, CVE-2012-5677, CVE-2012-5678)

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