NVD reports:
The update_dimensions function in libavcodec/vp8.c in
FFmpeg through 2.8.1, as used in Google Chrome before
46.0.2490.71 and other products, relies on a
coefficient-partition count during multi-threaded operation,
which allows remote attackers to cause a denial of service
(race condition and memory corruption) or possibly have
unspecified other impact via a crafted WebM file.
The ljpeg_decode_yuv_scan function in
libavcodec/mjpegdec.c in FFmpeg before 2.8.2 omits certain
width and height checks, which allows remote attackers to
cause a denial of service (out-of-bounds array access) or
possibly have unspecified other impact via crafted MJPEG
data.
The ff_hevc_parse_sps function in libavcodec/hevc_ps.c in
FFmpeg before 2.8.2 does not validate the Chroma Format
Indicator, which allows remote attackers to cause a denial
of service (out-of-bounds array access) or possibly have
unspecified other impact via crafted High Efficiency Video
Coding (HEVC) data.
The decode_uncompressed function in libavcodec/faxcompr.c
in FFmpeg before 2.8.2 does not validate uncompressed runs,
which allows remote attackers to cause a denial of service
(out-of-bounds array access) or possibly have unspecified
other impact via crafted CCITT FAX data.
The init_tile function in libavcodec/jpeg2000dec.c in
FFmpeg before 2.8.2 does not enforce minimum-value and
maximum-value constraints on tile coordinates, which allows
remote attackers to cause a denial of service (out-of-bounds
array access) or possibly have unspecified other impact via
crafted JPEG 2000 data.
The jpeg2000_read_main_headers function in
libavcodec/jpeg2000dec.c in FFmpeg before 2.6.5, 2.7.x
before 2.7.3, and 2.8.x through 2.8.2 does not enforce
uniqueness of the SIZ marker in a JPEG 2000 image, which
allows remote attackers to cause a denial of service
(out-of-bounds heap-memory access) or possibly have
unspecified other impact via a crafted image with two or
more of these markers.
Integer overflow in the ff_ivi_init_planes function in
libavcodec/ivi.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3,
and 2.8.x through 2.8.2 allows remote attackers to cause a
denial of service (out-of-bounds heap-memory access) or
possibly have unspecified other impact via crafted image
dimensions in Indeo Video Interactive data.
The smka_decode_frame function in libavcodec/smacker.c in
FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through
2.8.2 does not verify that the data size is consistent with
the number of channels, which allows remote attackers to
cause a denial of service (out-of-bounds array access) or
possibly have unspecified other impact via crafted Smacker
data.
