Description

A heap-based buffer overflow in the encode_slice function in
libavcodec/proresenc_kostya.c in FFmpeg before 2.0.6 can cause a crash,
allowing a malicious image file to cause a denial of service (CVE-2014-5271).

libavcodec/iff.c in FFmpeg before 2.0.6 allows an attacker to have an
unspecified impact via a crafted iff image, which triggers an out-of-bounds
array access, related to the rgb8 and rgbn formats (CVE-2014-5272).

libavcodec/mjpegdec.c in FFmpeg before 2.0.6 considers only dimension
differences, and not bits-per-pixel differences, when determining whether an
image size has changed, which allows remote attackers to cause a denial of
service (out-of-bounds access) or possibly have unspecified other impact via
crafted MJPEG data (CVE-2014-8541).

libavcodec/utils.c in FFmpeg before 2.0.6 omits a certain codec ID during
enforcement of alignment, which allows remote attackers to cause a denial of
service (out-of-bounds access) or possibly have unspecified other impact via
crafted JV data (CVE-2014-8542).

libavcodec/mmvideo.c in FFmpeg before 2.0.6 does not consider all lines of
HHV Intra blocks during validation of image height, which allows remote
attackers to cause a denial of service (out-of-bounds access) or possibly
have unspecified other impact via crafted MM video data (CVE-2014-8543).

libavcodec/tiff.c in FFmpeg before 2.0.6 does not properly validate
bits-per-pixel fields, which allows remote attackers to cause a denial of
service (out-of-bounds access) or possibly have unspecified other impact via
crafted TIFF data (CVE-2014-8544).

libavcodec/pngdec.c in FFmpeg before 2.0.6 accepts the monochrome-black
format without verifying that the bits-per-pixel value is 1, which allows
remote attackers to cause a denial of service (out-of-bounds access) or
possibly have unspecified other impact via crafted PNG data (CVE-2014-8545).

Integer underflow in libavcodec/cinepak.c in FFmpeg before 2.0.6 allows
remote attackers to cause a denial of service (out-of-bounds access) or
possibly have unspecified other impact via crafted Cinepak video data
(CVE-2014-8546).

libavcodec/gifdec.c in FFmpeg before 2.0.6 does not properly compute image
heights, which allows remote attackers to cause a denial of service
(out-of-bounds access) or possibly have unspecified other impact via crafted
GIF data (CVE-2014-8547).

Off-by-one error in libavcodec/smc.c in FFmpeg before 2.0.6 allows remote
attackers to cause a denial of service (out-of-bounds access) or possibly
have unspecified other impact via crafted Quicktime Graphics (aka SMC) video
data (CVE-2014-8548).
