    <p>
    Damian Frizza and Alfredo Ortega (Core Security Technologies)
    discovered a stack-based buffer overflow within the open_flac_file()
    function in the file demux_flac.c when parsing tags within a FLAC file
    (CVE-2008-0486). A buffer overflow when parsing ASF headers, which is
    similar to CVE-2006-1664, has also been discovered (CVE-2008-1110).
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to play specially crafted FLAC or
    ASF video streams with a player using xine-lib, potentially resulting
    in the execution of arbitrary code with the privileges of the user
    running the player.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All xine-lib users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-libs/xine-lib-1.1.10.1"</code>
  </resolution>
