Detailsinfo

A vulnerability was found in FFmpeg up to 0.10 (Multimedia Processing Software). It has been classified as critical. This affects the function srt_to_ass in the library libavcodec/srtdec.c of the file libavcodec/srtdec.c. The manipulation of the argument Function with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Heap-based buffer overflow in the vqa_decode_chunk function in the VQA codec (vqavideo.c) in libavcodec in Libav 0.5.x before 0.5.9, 0.6.x before 0.6.6, 0.7.x before 0.7.6, and 0.8.x before 0.8.2 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VQA media file in which the image size is not a multiple of the block size.

The weakness was presented 03/27/2012 by Fabian Yamaguchi (Website). The advisory is shared at ffmpeg.org. This vulnerability is uniquely identified as CVE-2012-0947 since 02/01/2012. The exploitability is told to be difficult. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 59094 (Debian DSA-2471-1 : ffmpeg - several vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 175239 (Debian Security Update for FFmpeg (DSA-2471)).

Upgrading to version 0.10.1 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (59094), SecurityFocus (BID 53389†), OSVDB (81060†) and Secunia (SA48770†). See VDB-5074, VDB-5075, VDB-61702 and VDB-61697 for similar entries. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
