FFmpeg before 0.5.4, as used in MPlayer and other products, allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a malformed WMV file.

The VC-1 decoding functionality in FFmpeg before 0.5.4, as used in MPlayer and other products, does not properly restrict read operations, which allows remote attackers to have an unspecified impact via a crafted VC-1 file, a related issue to CVE-2011-0723.

Multiple unspecified vulnerabilities in FFmpeg 0.4.x through 0.6.x, as used in MPlayer 1.0 and other products, in Mandriva Linux 2009.0, 2010.0, and 2010.1; Corporate Server 4.0 (aka CS4.0); and Mandriva Enterprise Server 5 (aka MES5) have unknown impact and attack vectors, related to issues "originally discovered by Google Chrome developers."

FFmpeg before 0.5.4, as used in MPlayer and other products, 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.

FFmpeg 0.5.x, as used in MPlayer and other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a malformed VC-1 file.

libavcodec/vorbis_dec.c in the Vorbis decoder in FFmpeg 0.6.1 and earlier allows remote attackers to cause a denial of service (application crash) via a crafted .ogg file, related to the vorbis_floor0_decode function. NOTE: this might overlap CVE-2011-0480.

flicvideo.c in libavcodec 0.6 and earlier in FFmpeg, as used in MPlayer and other products, allows remote attackers to execute arbitrary code via a crafted flic file, related to an "arbitrary offset dereference vulnerability."

FFmpeg 0.5 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted MOV container with improperly ordered tags that cause (1) mov.c and (2) utils.c to use inconsistent codec types and identifiers, leading to processing of a video-structure pointer by the mp3 decoder, and a stack-based buffer overflow.

vorbis_dec.c in FFmpeg 0.5 uses an assignment operator when a comparison operator was intended, which might allow remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted file that modifies a loop counter and triggers a heap-based buffer overflow.

Integer overflow in FFmpeg 0.5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors.
