CVSS Base Vector:

Technical Details:
Multiple vulnerabilities were found in the ffmpeg, a multimedia player, server and encoder: CVE-2011-3362 An integer signedness error in decode_residual_block function of the Chinese AVS video (CAVS) decoder in libavcodec can lead to denial of service (memory corruption and application crash) or possible code execution via a crafted CAVS file. CVE-2011-3973/CVE-2011-3974 Multiple errors in the Chinese AVS video (CAVS) decoder can lead to denial of service (memory corruption and application crash) via an invalid bitstream. CVE-2011-3504 A memory allocation problem in the Matroska format decoder can lead to code execution via a crafted file. For the stable distribution (squeeze), this problem has been fixed in version 4:0.5.5-1. For the unstable distribution (sid), this problem has been fixed in version 4:0.7.2-1 of the libav source Linux Distribution Package. Security support for ffmpeg has been discontinued for the oldstable distribution (lenny) before in DSA 2306. The current version in oldstable is not supported by upstream anymore and is affected by several security issues. Backporting fixes for these and any future issues has become unfeasible and therefore we needed to drop our security support for the version in oldstable.

We recommend that you upgrade your ffmpeg Linux Distribution Packages.

The remote host is missing an update to ffmpeg announced via advisory DSA 2336-1.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
