Mandriva Linux Security Advisory : ffmpeg (MDVSA-2012:076)

critical Nessus Plugin ID 61951

Language:

Synopsis

The remote Mandriva Linux host is missing one or more security updates.

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).

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.
