  <description>
    <p>
    Multiple vulnerabilities have been reported in MPlayer:
    </p>
    <ul>
    <li>A
    stack-based buffer overflow was found in the str_read_packet() function
    in libavformat/psxstr.c when processing crafted STR files that
    interleave audio and video sectors (CVE-2008-3162).</li>
    <li>Felipe
    Andres Manzano reported multiple integer underflows in the
    demux_real_fill_buffer() function in demux_real.c when processing
    crafted Real Media files that cause the stream_read() function to read
    or write arbitrary memory (CVE-2008-3827).</li>
    <li>Tobias Klein
    reported a stack-based buffer overflow in the demux_open_vqf() function
    in libmpdemux/demux_vqf.c when processing malformed TwinVQ files
    (CVE-2008-5616).</li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted STR,
    Real Media, or TwinVQ file to execute arbitrary code or cause a Denial of
    Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All MPlayer users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-video/mplayer-1.0_rc2_p28058-r1 "</code>
