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

gst-plugins-libav is affected because this package is bundling a
vulnerable FFmpeg version.

Impact
=====
A remote attacker could entice a user or automated system using FFmpeg
to process a specially crafted file, resulting in the execution of
arbitrary code or a Denial of Service.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All FFmpeg users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-video/ffmpeg-3.2.4"

All gst-plugins-libav users should upgrade to the latest version:

  # emerge --sync
  # emerge -a --oneshot -v ">=media-plugins/gst-plugins-libav-1.10.4"
