2.1 does not properly maintain a pointer to pixel data, which allows
remote attackers to cause a denial of service (out-of-bounds array
access) or possibly have unspecified other impact via crafted Apple RPZA
data.

http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2013-7009

gst-ffmpeg: Security Advisory - ffmpeg - CVE-2013-0855

Integer overflow in the alac_decode_close function in libavcodec/alac.c
in FFmpeg before 1.1 allows remote attackers to have an unspecified
impact via a large number of samples per frame in Apple Lossless Audio
Codec (ALAC) data, which triggers an out-of-bounds array access.

0.7.8, and 0.8.x before 0.8.8 allows remote attackers to execute
arbitrary code via unspecified vectors.

http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2011-4351

gst-ffmpeg: Security Advisory - ffmpeg - CVE-2013-0848

The decode_init function in libavcodec/huffyuv.c in FFmpeg before 1.1
allows remote attackers to have an unspecified impact via a crafted
width in huffyuv data with the predictor set to median and the
colorspace set to YUV422P, which triggers an out-of-bounds array access.

http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2013-0848

gst-ffmpeg: Security Advisory - ffmpeg - CVE-2011-3944

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.

gst-ffmpeg: Security Advisory - ffmpeg - CVE-2013-7010

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.

http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2013-7010

gst-ffmpeg: Security Advisory - ffmpeg - CVE-2011-3941

The decode_mb function in libavcodec/error_resilience.c in FFmpeg before
0.10 allows remote attackers to have an unspecified impact via vectors
related to an uninitialized block index, which triggers an out-of-bound
write.

http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2011-3941

gst-ffmpeg: Security Advisory - ffmpeg - CVE-2013-0846

Array index error in the qdm2_decode_super_block function in
libavcodec/qdm2.c in FFmpeg before 1.1 allows remote attackers to have
an unspecified impact via crafted QDM2 data, which triggers an
out-of-bounds array access.

http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2013-0846

gst-ffmpeg: Security Advisory - ffmpeg - CVE-2012-6618

The av_probe_input_buffer function in libavformat/utils.c in FFmpeg
before 1.0.2, when running with certain -probesize values, allows remote
attackers to cause a denial of service (crash) via a crafted MP3 file,
possibly related to frame size or lack of sufficient frames to estimate
rate.
