Synopsis
=======
A buffer overflow in GStreamer could allow remote attackers to execute
arbitrary code or cause Denial of Service.

Background
=========
GStreamer is an open source multimedia framework.

Affected packages
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-libs/gstreamer         < 1.4.5                    >= 1.4.5

Description
==========
A buffer overflow vulnerability has been found in the parsing of H.264
formatted video.

Impact
=====
A remote attacker could entice a user to open a specially crafted H.264
formatted video using an application linked against GStreamer, possibly
resulting in execution of arbitrary code with the privileges of the
process or a Denial of Service condition.

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

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

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-libs/gstreamer-1.4.5"
