Mandriva Linux Security Advisory 2012-075 - 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. 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 file, related to the decode_residual_block, check_for_slice, and cavs_decode_frame functions, a different vulnerability than CVE-2011-3362. Various other issues were also addressed.

Package : ffmpeg
Date : May 15, 2012
Affected: 2010.1
_______________________________________________________________________

Problem Description:

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).

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