Synopsis
========

Multiple vulnerabilities have been found in Libav, allowing attackers
to execute arbitrary code or cause Denial of Service.

Background
==========

Libav is a complete solution to record, convert and stream audio and
video.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-video/libav            < 0.8.7                    >= 0.8.7 

Description
===========

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 or a
Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Libav users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-video/libav-0.8.7"

Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying these packages.
