| Descripción: | Summary:
The remote host is missing an update for the 'ffmpeg'
package(s) announced via the referenced advisory.
Vulnerability Insight:
Multiple vulnerabilities has been found and corrected in ffmpeg:
The Matroska format decoder in FFmpeg does not properly allocate
memory, which allows remote attackers to execute arbitrary code via
a crafted file (CVE-2011-3362, CVE-2011-3504).
cavsdec.c in libavcodec in FFmpeg allows remote attackers to cause
a denial of service (incorrect write operation and application
crash) via an invalid bitstream in a Chinese AVS video (aka CAVS)
file, related to the decode_residual_block, check_for_slice,
and cavs_decode_frame functions, a different vulnerability than
CVE-2011-3362 (CVE-2011-3973).
Double free vulnerability in the Theora decoder in FFmpeg allows remote
attackers to cause a denial of service or possibly have unspecified
other impact via a crafted stream (CVE-2011-3892).
FFmpeg does not properly implement the MKV and Vorbis media
handlers, which allows remote attackers to cause a denial of service
(out-of-bounds read) via unspecified vectors (CVE-2011-3893).
Heap-based buffer overflow in the Vorbis decoder in FFmpeg allows
remote attackers to cause a denial of service or possibly have
unspecified other impact via a crafted stream (CVE-2011-3895).
