    file formats.

    <p>
    Sven Tantau discovered a heap overflow in the code handling the
    strf chunk of PCM audio streams.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could craft a malicious video or audio file which,
    when opened using MPlayer, would end up executing arbitrary code on the
    victim's computer with the permissions of the user running MPlayer.
    </p>
  </impact>
  <workaround>
    <p>
    You can mitigate the issue by adding "ac=-pcm," to your MPlayer
    configuration file (note that this will prevent you from playing
    uncompressed audio).
    </p>
  </workaround>
  <resolution>
    <p>
    All MPlayer users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-video/mplayer-1.0_pre7-r1&quot;</code>
