  <description>
    <p>A buffer overflow vulnerability has been found in the parsing of H.264
      formatted video.
    </p>
  </description>
  <impact type="normal">
    <p>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.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All GStreamer users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=media-libs/gstreamer-1.4.5"
    </code>
