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 dirac_decode_data_unit function in libavcodec/diracdec.c in FFmpeg before 0.10 allows remote attackers to have an unspecified impact via a crafted value in the reference pictures number.

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 through 4.2 has a "Conditional jump or move depends on uninitialised value" issue in h2645_parse because alloc_rbsp_buffer in libavcodec/h2645_parse.c mishandles rbsp_buffer.

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.

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/hevcdec.c in FFmpeg 3.4 and 4.1.2 mishandles detection of duplicate first slices, which allows remote attackers to cause a denial of service (NULL pointer dereference and out-of-array access) or possibly have unspecified other impact via crafted HEVC data.

The studio profile decoder in libavcodec/mpeg4videodec.c in FFmpeg 4.0 before 4.0.4 and 4.1 before 4.1.2 allows remote attackers to cause a denial of service (out-of-array access) or possibly have unspecified other impact via crafted MPEG-4 video data.

Integer Overflow vulnerability in function filter16_sobel in libavfilter/vf_convolution.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts.

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."

block_cmp() in libavcodec/zmbvenc.c in FFmpeg 4.1.3 has a heap-based buffer over-read.

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.

FFmpeg before commit 2b46ebdbff1d8dec7a3d8ea280a612b91a582869 contains a Buffer Overflow vulnerability in asf_o format demuxer that can result in heap-buffer-overflow that may result in remote code execution. This attack appears to be exploitable via specially crafted ASF file that has to be provided as input to FFmpeg. This vulnerability appears to have been fixed in 2b46ebdbff1d8dec7a3d8ea280a612b91a582869 and later.

The smacker_decode_header_tree function in libavcodec/smacker.c in FFmpeg before 0.10 allows remote attackers to have an unspecified impact via crafted Smacker data.

The read_header function in libavcodec/ffv1dec.c in FFmpeg before 2.1 does not prevent changes to global parameters, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted FFV1 data.

Multiple integer signedness errors in libavcodec/dsputil.c in FFmpeg before 2.1 allow remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted data.

Double free vulnerability in the vp3_update_thread_context function in libavcodec/vp3.c in FFmpeg before 0.10 allows remote attackers to have an unspecified impact via crafted vp3 data.

Heap-based buffer overflow in the decode_dds1 function in libavcodec/dfa.c in FFmpeg before 2.8.12, 3.0.x before 3.0.8, 3.1.x before 3.1.8, 3.2.x before 3.2.5, and 3.3.x before 3.3.1 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted file.
