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.

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.

We recommend that you upgrade your ffmpeg packages.");
