Google Chrome before 15.0.874.120 does not properly implement the MKV and Vorbis media handlers, which allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors.

The remote host is affected by the vulnerability described in GLSA-201310-12 (FFmpeg: Multiple vulnerabilities)

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

    A remote attacker could entice a user to open a specially crafted media       file, possibly leading to the execution of arbitrary code with the       privileges of the user running the application or a Denial of Service.
  Workaround :

    There is no known workaround at this time.

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

Multiple vulnerabilities has been found and corrected in ffmpeg :

The Matroska format decoder in FFmpeg does not properly allocate memory, which allows remote attackers to execute arbitrary code via a crafted file (CVE-2011-3362, CVE-2011-3504).

cavsdec.c in libavcodec in FFmpeg allows remote attackers to cause a denial of service (incorrect write operation and application crash) via an invalid bitstream in a Chinese AVS video (aka CAVS) file, related to the decode_residual_block, check_for_slice, and cavs_decode_frame functions, a different vulnerability than CVE-2011-3362 (CVE-2011-3973).

Integer signedness error in the decode_residual_inter function in cavsdec.c in libavcodec in FFmpeg allows remote attackers to cause a denial of service (incorrect write operation and application crash) via an invalid bitstream in a Chinese AVS video (aka CAVS) file, a different vulnerability than CVE-2011-3362 (CVE-2011-3974).

Double free vulnerability in the Theora decoder in FFmpeg allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted stream (CVE-2011-3892).

FFmpeg does not properly implement the MKV and Vorbis media handlers, which allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors (CVE-2011-3893).

Heap-based buffer overflow in the Vorbis decoder in FFmpeg allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted stream (CVE-2011-3895).

An error within the QDM2 decoder (libavcodec/qdm2.c) can be exploited to cause a buffer overflow (CVE-2011-4351).

An integer overflow error within the 'vp3_dequant()' function (libavcodec/vp3.c) can be exploited to cause a buffer overflow (CVE-2011-4352).

Errors within the 'av_image_fill_pointers()', the 'vp5_parse_coeff()', and the 'vp6_parse_coeff()' functions can be exploited to trigger out-of-bounds reads (CVE-2011-4353).

It was discovered that Libav incorrectly handled certain malformed VMD files. If a user were tricked into opening a crafted VMD 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 (CVE-2011-4364).

It was discovered that Libav incorrectly handled certain malformed SVQ1 streams. If a user were tricked into opening a crafted SVQ1 stream 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 (CVE-2011-4579).

Multiple input validations in the decoders/ demuxers for Westwood Studios VQA, Apple MJPEG-B, Theora, Matroska, Vorbis, Sony ATRAC3, DV, NSV, files could lead to the execution of arbitrary code (CVE-2011-3929, CVE-2011-3936, CVE-2011-3937, CVE-2011-3940, CVE-2011-3945, CVE-2011-3947, CVE-2012-0853, CVE-2012-0858).

The updated packages have been upgraded to the 0.7.12 version where these issues has been corrected.

The updated packages have been upgraded to the 0.6.5 version where these issues has been corrected.

Several vulnerabilities have been discovered in FFmpeg, a multimedia player, server and encoder. Multiple input validations in the decoders/ demuxers for Westwood Studios VQA, Apple MJPEG-B, Theora, Matroska, Vorbis, Sony ATRAC3, DV, NSV, files could lead to the execution of arbitrary code.

These issues were discovered by Aki Helin, Mateusz Jurczyk, Gynvael Coldwind, and Michael Niedermayer.

The remote host is affected by the vulnerability described in GLSA-201111-05 (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. The attacker also could cause       a Java applet to run without user confirmation.
  Workaround :

    There is no known workaround at this time.
