The decode_init function in libavcodec/huffyuv.c in FFmpeg before 1.1 allows remote attackers to have an unspecified impact via a crafted width in huffyuv data with the predictor set to median and the colorspace set to YUV422P, which triggers an out-of-bounds array access.
Array index error in the qdm2_decode_super_block function in libavcodec/qdm2.c in FFmpeg before 1.1 allows remote attackers to have an unspecified impact via crafted QDM2 data, which triggers an out-of-bounds array access.
Off-by-one error in the adpcm_decode_frame function in libavcodec/adpcm.c in FFmpeg before 1.0.4 allows remote attackers to have an unspecified impact via crafted DK4 data, which triggers an out-of-bounds array access.
The field_end function in libavcodec/h264.c in FFmpeg before 1.1.2 allows remote attackers to have an unspecified impact via crafted H.264 data, related to an SPS and slice mismatch and an out-of-bounds array access.
libavcodec/huffyuvdec.c in FFmpeg before 1.1.2 allows remote attackers to have an unspecified impact via crafted Huffyuv data, related to an out-of-bounds write and (1) unchecked return codes from the init_vlc function and (2) "len==0 cases."
The decode_slice_header function in libavcodec/h264.c in FFmpeg before 1.1.2 does not properly check when the pixel format changes, which allows remote attackers to have unspecified impact via crafted H.264 video data, related to an out-of-bounds array access.
The vqa_decode_chunk function in libavcodec/vqavideo.c in FFmpeg before 1.0.4 and 1.1.x before 1.1.2 allows remote attackers to have an unspecified impact via a large (1) cbp0 or (2) cbpz chunk in Westwood Studios VQA Video file, which triggers an out-of-bounds write.
The ff_er_frame_end function in libavcodec/error_resilience.c in FFmpeg before 1.0.4 and 1.1.x before 1.1.1 does not properly verify that a frame is fully initialized, which allows remote attackers to trigger a NULL pointer dereference via crafted picture data.
The read_header function in libavcodec/shorten.c in FFmpeg before 1.1.3 allows remote attackers to have an unspecified impact via an invalid channel count, related to "freeing invalid addresses."
The mm_decode_inter function in mmvideo.c in libavcodec in FFmpeg before 1.2.1 does not validate the relationship between a horizontal coordinate and a width value, which allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) via crafted American Laser Games (ALG) MM Video data.
The rle_unpack function in vmdav.c in libavcodec in FFmpeg git 20130328 through 20130501 does not properly use the bytestream2 API, which allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) via crafted RLE data. NOTE: the vendor has listed this as an issue fixed in 1.2.1, but the issue is actually in new code that was not shipped with the 1.2.1 release or any earlier release.
The msrle_decode_8_16_24_32 function in msrledec.c in libavcodec in FFmpeg through 1.1.3 does not properly determine certain end pointers, which allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) or possibly have unspecified other impact via crafted Microsoft RLE data.
The iff_read_header function in iff.c in libavformat in FFmpeg through 1.1.3 does not properly handle data sizes for Interchange File Format (IFF) data during operations involving a CMAP chunk or a video codec, which allows remote attackers to cause a denial of service (integer overflow, out-of-bounds array access, and application crash) or possibly have unspecified other impact via a crafted header.
The ff_h264_decode_seq_parameter_set function in h264_ps.c in libavcodec in FFmpeg before 1.1.3 does not validate the relationship between luma depth and chroma depth, which allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) or possibly have unspecified other impact via crafted H.264 data.
Buffer overflow in the vorbis_parse_setup_hdr_floors function in the Vorbis decoder in vorbisdec.c in libavcodec in FFmpeg through 1.1.3, as used in Google Chrome before 25.0.1364.97 on Windows and Linux and before 25.0.1364.99 on Mac OS X and other products, allows remote attackers to cause a denial of service (divide-by-zero error or out-of-bounds array access) or possibly have unspecified other impact via vectors involving a zero value for a bark map size.
Use-after-free vulnerability in Google Chrome before 24.0.1312.52 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors involving seek operations on video data.
Unspecified vulnerability in libavcodec/indeo3.c in FFmpeg before 0.11 and Libav 0.8.x before 0.8.5 has unknown impact and attack vectors, related to "reallocation code" and the luma height and width.
Double free vulnerability in the mpeg_decode_frame function in libavcodec/mpeg12.c in FFmpeg before 0.11, and Libav 0.7.x before 0.7.7 and 0.8.x before 0.8.5, has unknown impact and attack vectors, related to resetting the data size value.
Unspecified vulnerability in libavcodec/avs.c in FFmpeg before 0.11, and Libav 0.7.x before 0.7.7 and 0.8.x before 0.8.4, has unknown impact and attack vectors, related to dimensions and "out of array writes."
