CVE-2011-4579

Status Candidate

Overview

The svq1_decode_frame function in the SVQ1 decoder (svq1dec.c) in libavcodec in FFmpeg 0.5.x before 0.5.7, 0.6.x before 0.6.4, 0.7.x before 0.7.9, and 0.8.x before 0.8.8; and in Libav 0.5.x before 0.5.6, 0.6.x before 0.6.4, and 0.7.x before 0.7.3 allows remote attackers to cause a denial of service (memory corruption) via a crafted SVQ1 stream, related to "dimensions changed."

Mandriva Linux Security Advisory 2012-074 - 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. 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 via an invalid bitstream in a Chinese AVS video file, a different vulnerability than CVE-2011-3362. Various other issues have also been addressed.

Ubuntu Security Notice 1333-1 - Steve Manzuik discovered that Libav incorrectly handled certain malformed Matroska files. If a user were tricked into opening a crafted Matroska 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. This issue only affected Ubuntu 11.04. Phillip Langlois discovered that Libav incorrectly handled certain malformed QDM2 streams. If a user were tricked into opening a crafted QDM2 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. Various other issues were also addressed.
