The decode_init function in kmvc.c in libavcodec in FFmpeg before 0.10 and in Libav 0.5.x before 0.5.9, 0.6.x before 0.6.6, 0.7.x before 0.7.6, and 0.8.x before 0.8.1 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a large palette size in a KMVC encoded file.
The ff_h264_decode_seq_parameter_set function in h264_ps.c in libavcodec in FFmpeg before 0.9.1 and in Libav 0.5.x before 0.5.9, 0.6.x before 0.6.6, 0.7.x before 0.7.6, and 0.8.x before 0.8.3 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted H.264 file, related to the chroma_format_idc value.
The adpcm_decode_frame function in adpcm.c in libavcodec in FFmpeg before 0.9.1 and in Libav 0.5.x before 0.5.9, 0.6.x before 0.6.6, 0.7.x before 0.7.6, and 0.8.x before 0.8.3 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via an ADPCM file with the number of channels not equal to two.
The render_line function in the vorbis codec (vorbis.c) in libavcodec in FFmpeg before 0.9.1 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted Vorbis file, related to a large multiplier. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-3893.
Integer underflow in the asfrtp_parse_packet function in libavformat/rtpdec_asf.c in FFmpeg before 0.8.3 allows remote attackers to execute arbitrary code via a crafted ASF packet.
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.
