Synopsis
========

Multiple vulnerabilities have been found in FFmpeg, the worst of which
allows remote attackers to execute arbitrary code.

Background
==========

FFmpeg is a complete, cross-platform solution to record, convert and
stream audio and video.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-video/ffmpeg < 3.2.4 >= 3.2.4
2 media-plugins/gst-plugins-libav
< 1.10.4 >= 1.10.4
-------------------------------------------------------------------
2 affected packages

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"
