Several vulnerabilities have been discovered in FFmpeg, a multimedia player, server and encoder. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2010-3908     FFmpeg before 0.5.4, allows remote attackers to cause a     denial of service (memory corruption and application     crash) or possibly execute arbitrary code via a     malformed WMV file.

  - CVE-2010-4704     libavcodec/vorbis_dec.c in the Vorbis decoder in FFmpeg     allows remote attackers to cause a denial of service     (application crash) via a crafted Ogg file, related to     the vorbis_floor0_decode function.

  - CVE-2011-0480     Multiple buffer overflows in vorbis_dec.c in the Vorbis     decoder in FFmpeg allow remote attackers to cause a     denial of service (memory corruption and application     crash) or possibly have unspecified other impact via a     crafted WebM file, related to buffers for the channel     floor and the channel residue.

  - CVE-2011-0722     FFmpeg allows remote attackers to cause a denial of     service (heap memory corruption and application crash)     or possibly execute arbitrary code via a malformed     RealMedia file.

Multiple vulnerabilities have been identified and fixed in mplayer :

Several vulnerabilities have been discovered in FFmpeg coders, which are used by MPlayer and other applications.

  - CVE-2010-3429     Cesar Bernardini and Felipe Andres Manzano reported an     arbitrary offset dereference vulnerability in the     libavcodec, in particular in the FLIC file format     parser. A specific FLIC file may exploit this     vulnerability and execute arbitrary code. Mplayer is     also affected by this problem, as well as other software     that use this library.

  - CVE-2010-4704     Greg Maxwell discovered an integer overflow the Vorbis     decoder in FFmpeg. A specific Ogg file may exploit this     vulnerability and execute arbitrary code.

  - CVE-2010-4705     A potential integer overflow has been discovered in the     Vorbis decoder in FFmpeg.

This upload also fixes an incomplete patch from DSA-2000-1. Michael Gilbert noticed that there was remaining vulnerabilities, which may cause a denial of service and potentially execution of arbitrary code.
