cavsdec.c in libavcodec in FFmpeg before 0.7.4 and 0.8.x before 0.8.3 allows remote attackers to cause a denial of service (incorrect write operation and application crash) via an invalid bitstream in a Chinese AVS video (aka CAVS) file, related to the decode_residual_block, check_for_slice, and cavs_decode_frame functions, a different vulnerability than CVE-2011-3362.

Integer signedness error in the decode_residual_inter function in cavsdec.c in libavcodec in FFmpeg before 0.7.4 and 0.8.x before 0.8.3 allows remote attackers to cause a denial of service (incorrect write operation and application crash) via an invalid bitstream in a Chinese AVS video (aka CAVS) file, a different vulnerability than CVE-2011-3362.

Integer signedness error in the decode_residual_block function in cavsdec.c in libavcodec in FFmpeg before 0.7.3 and 0.8.x before 0.8.2, and libav through 0.7.1, allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted Chinese AVS video (aka CAVS) file.

The Matroska format decoder in FFmpeg before 0.8.3 does not properly allocate memory, which allows remote attackers to execute arbitrary code via a crafted file.

sp5xdec.c in the Sunplus SP5X JPEG decoder in libavcodec in FFmpeg before 0.6.3 and libav through 0.6.2, as used in VideoLAN VLC media player 1.1.9 and earlier and other products, performs a write operation outside the bounds of an unspecified array, which allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a malformed AMV file.

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.

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.
