libavcodec/utvideodec.c in FFmpeg before 2.5.2 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 (1) restore_median and (2) restore_median_il functions.

The remote host is affected by the vulnerability described in GLSA-201603-06 (FFmpeg: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in FFmpeg.  Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could possibly execute arbitrary code or cause a       Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

The Mageia project reports :

Avidemux is built with a bundled set of FFmpeg libraries. The bundled FFmpeg version has been updated from 1.2.10 to 1.2.12 to fix these security issues and other bugs fixed upstream in FFmpeg.

The libav project reports :

utvideodec: Handle slice_height being zero (CVE-2014-9604)

tiff: Check that there is no aliasing in pixel format selection (CVE-2014-8544)

It was discovered that Libav incorrectly handled certain malformed media files. If a user were tricked into opening a crafted media file, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several security issues have been corrected in multiple demuxers and decoders of the libav multimedia library. A full list of the changes is available at
