Synopsis
=======
FFmpeg is vulnerable to multiple buffer overflows that might be
exploited to execute arbitrary code.

Background
=========
FFmpeg is a very fast video and audio converter.

Affected packages
================
    -------------------------------------------------------------------
     Package             /      Vulnerable      /           Unaffected
    -------------------------------------------------------------------
  1  media-video/ffmpeg      < 0.4.9_p20060530      >= 0.4.9_p20060530

Description
==========
FFmpeg contains buffer overflows in the AVI processing code.

Impact
=====
An attacker could trigger the buffer overflows by enticing a user to
load a specially crafted AVI file in an application using the FFmpeg
library. This might result in the execution of arbitrary code in the
context of the running application.

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-0.4.9_p20060530"

Availability
===========
This GLSA and any updates to it are available for viewing at
