Multiple unspecified vulnerabilities in libavcodec/wmalosslessdec.c in FFmpeg before 0.11 have unknown impact and attack vectors related to (1) size of "mclms arrays," (2) "a get_bits(0) in decode_ac_filter," and (3) "too many bits in decode_channel_residues()."
Unspecified vulnerability in the vc1_decode_frame function in libavcodec/vc1dec.c in FFmpeg before 0.11 and Libav 0.8.x before 0.8.4 has unknown impact and attack vectors, related to inconsistencies in "coded slice positions and interlacing" that trigger "out of array writes."
Integer overflow in the ff_j2k_dwt_init function in libavcodec/j2k_dwt.c in FFmpeg before 0.9.1 allows remote attackers to cause a denial of service (segmentation fault and application crash) via a crafted JPEG2000 image that triggers an incorrect check for a negative value.
Heap-based buffer overflow in the get_sot function in the J2K decoder (j2k.c) in libavcodec in FFmpeg before 0.9.1 allows remote attackers to cause a denial of service (application crash) via unspecified vectors related to the curtileno variable.
The svq1_decode_frame function in the SVQ1 decoder (svq1dec.c) in libavcodec in FFmpeg 0.5.x before 0.5.7, 0.6.x before 0.6.4, 0.7.x before 0.7.9, and 0.8.x before 0.8.8; and in Libav 0.5.x before 0.5.6, 0.6.x before 0.6.4, and 0.7.x before 0.7.3 allows remote attackers to cause a denial of service (memory corruption) via a crafted SVQ1 stream, related to "dimensions changed."
The decode_frame function in the KVG1 decoder (kgv1dec.c) in libavcodec in FFmpeg 0.7.x before 0.7.12 and 0.8.x before 0.8.11, and in Libav 0.5.x before 0.5.9, 0.6.x before 0.6.6, 0.7.x before 0.7.5, and 0.8.x before 0.8.1, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted media file.
Integer overflow in the vp3_dequant function in the VP3 decoder (vp3.c) in libavcodec in FFmpeg 0.5.x before 0.5.7, 0.6.x before 0.6.4, 0.7.x before 0.7.9, and 0.8.x before 0.8.8; and in Libav 0.5.x before 0.5.6, 0.6.x before 0.6.4, and 0.7.x before 0.7.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VP3 stream, which triggers a buffer overflow.
The (1) av_image_fill_pointers, (2) vp5_parse_coeff, and (3) vp6_parse_coeff functions in FFmpeg 0.5.x before 0.5.7, 0.6.x before 0.6.4, 0.7.x before 0.7.9, and 0.8.x before 0.8.8; and in Libav 0.5.x before 0.5.6, 0.6.x before 0.6.4, and 0.7.x before 0.7.3 allow remote attackers to cause a denial of service (out-of-bounds read) via a crafted VP5 or VP6 stream.
Buffer overflow in the Sierra VMD decoder in libavcodec in FFmpeg 0.5.x before 0.5.7, 0.6.x before 0.6.4, 0.7.x before 0.7.9 and 0.8.x before 0.8.8; and in Libav 0.5.x before 0.5.6, 0.6.x before 0.6.4, and 0.7.x before 0.7.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VMD file, related to corrupted streams.
The dpcm_decode_frame function in libavcodec/dpcm.c in FFmpeg before 0.9.1 does not use the proper pointer after an audio API change, which allows remote attackers to cause a denial of service (application crash) via unspecified vectors, which triggers a heap-based buffer overflow.
