Description

The mjpeg_decode_app function in libavcodec/mjpegdec.c in FFMpeg before 2.0.7
allows remote attackers to cause a denial of service (out-of-bounds heap
access) and possibly have other unspecified impact via vectors related to
LJIF tags in an MJPEG file (CVE-2014-9316).

The decode_ihdr_chunk function in libavcodec/pngdec.c in FFMpeg before 2.0.7
allows remote attackers to cause a denial of service (out-of-bounds heap
access) and possibly have other unspecified impact via an IDAT before an IHDR
in a PNG file (CVE-2014-9317).

The raw_decode function in libavcodec/rawdec.c in FFMpeg before 2.0.7 allows
remote attackers to cause a denial of service (out-of-bounds heap access) and
possibly have other unspecified impact via a crafted .cine file that triggers
the avpicture_get_size function to return a negative frame size
(CVE-2014-9318).

The vmd_decode function in libavcodec/vmdvideo.c in FFmpeg before 2.0.7 does
not validate the relationship between a certain length value and the frame
width, which allows remote attackers to cause a denial of service
(out-of-bounds array access) or possibly have unspecified other impact via
crafted Sierra VMD video data (CVE-2014-9603).

libavcodec/utvideodec.c in FFmpeg before 2.0.7 does not check for a zero
value of a slice height, which allows remote attackers to cause a denial of
service (out-of-bounds array access) or possibly have unspecified other
impact via crafted Ut Video data, related to the restore_median and
restore_median_il functions (CVE-2014-9604).

An attacker can force a read at an invalid address in mjpegdec.c of FFmpeg,
in order to trigger a denial of service (CVE-2015-1872).

The msrle_decode_pal4 function in libavcodec/msrledec.c in FFmpeg before
2.0.7 has an out-of-bounds array access that may allow remote attackers to
cause a denial of service or possibly have unspecified other impact via a
crafted BMP file (CVE-2015-3395).

Use-after-free vulnerability in the ff_h264_free_tables function in
libavcodec/h264.c in FFmpeg before 2.0.7 allows remote attackers to cause a
denial of service or possibly have unspecified other impact via crafted H.264
data in an MP4 file, as demonstrated by an HTML VIDEO element that references
H.264 data (CVE-2015-3417).
