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.

libavcodec/jpeg2000dec.c in FFmpeg before 2.1 does not ensure the use of valid code-block dimension values, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG2000 data.

The read_header function in libavcodec/ffv1dec.c in FFmpeg before 2.1 does not properly enforce certain bit-count and colorspace constraints, 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.

The flashsv_decode_frame function in libavcodec/flashsv.c in FFmpeg before 2.1 does not properly validate a certain height value, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Flash Screen Video data.

libavcodec/jpeg2000.c in FFmpeg before 2.1 allows remote attackers to cause a denial of service (invalid pointer dereference) or possibly have unspecified other impact via crafted JPEG2000 data.

The decode_slice_header function in libavcodec/h264.c in FFmpeg before 2.1 incorrectly relies on a certain droppable field, which allows remote attackers to cause a denial of service (deadlock) or possibly have unspecified other impact via crafted H.264 data.

The get_cox function in libavcodec/jpeg2000dec.c in FFmpeg before 2.1 does not properly validate the reduction factor, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG2000 data.

The filter_frame function in libavfilter/vf_fps.c in FFmpeg before 2.1 does not properly ensure the availability of FIFO content, which allows remote attackers to cause a denial of service (double free) or possibly have unspecified other impact via crafted data.

The ff_combine_frame function in libavcodec/parser.c in FFmpeg before 2.1 does not properly handle certain memory-allocation errors, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted data.

The get_siz function in libavcodec/jpeg2000dec.c in FFmpeg before 2.1 does not ensure the expected sample separation, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG2000 data.
