"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."

"Upgrade the ffmpeg packages.

For the stable distribution (squeeze), this problem has been fixed in
version 4:0.5.4-1.

Security support for ffmpeg has been discontinued for the oldstable
distribution (lenny). 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 need to drop our security support for the
version in oldstable."
