The mov_read_dref function in libavformat/mov.c in Libav before 11.7 and FFmpeg before 0.11 allows remote attackers to cause a denial of service (memory corruption) or execute arbitrary code via the entries value in a dref box in an MP4 file.

The remote host is affected by the vulnerability described in GLSA-201705-08 (libav: Multiple vulnerabilities)

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

    A remote attacker could entice a user to open a specially crafted media       file in an application linked against libav, possibly resulting in       execution of arbitrary code with the privileges of the application, a       Denial of Service condition or access the content of arbitrary local       files.
  Workaround :

    There is no known workaround at this time.

This update for libav fixes the two following security issues :

  - CVE-2016-3062: A MP4 memory corruption was fixed that     could lead to crashes or code execution. (boo#984487)

  - CVE-2015-5479: A crash due to a divide by zero was fixed     in ff_h263_decode_mba() that could lead to decoder     crashes. (boo#949760)

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 https://git.libav.org/?p=libav.git;a=blob;f=Changelog;hb=refs/tags/v11 .7

It was discovered that there was a memory corruption issue in libav (a multimedia player, server, encoder and transcoder) when parsing .mp4 files which could lead to crash or possibly execute arbitrary code.

For Debian 7 'Wheezy', this issue has been fixed in libav version 6:0.8.17-2+deb7u2.

We recommend that you upgrade your libav packages.
