    <p>
    VLC is a cross-platform media player and streaming server.

    <p>
    Multiple vulnerabilities were found in VLC:
    </p>
    <ul>
    <li>
    Luigi Auriemma discovered that the stack-based buffer overflow when
    reading subtitles, which has been reported as CVE-2007-6681 in GLSA
    200803-13, was not properly fixed (CVE-2008-1881).
    </li>
    <li>
    Alin Rad Pop of Secunia reported an array indexing vulnerability in the
    sdpplin_parse() function when processing streams from RTSP servers in
    Xine code, which is also used in VLC (CVE-2008-0073).
    </li>
    <li>
    Drew Yao and Nico Golde reported an integer overflow in the
    MP4_ReadBox_rdrf() function in the file libmp4.c leading to a
    heap-based buffer overflow when reading MP4 files (CVE-2008-1489).
    </li>
    <li>Drew Yao also reported integer overflows in the MP4 demuxer,
    the Real demuxer and in the Cinepak codec, which might lead to buffer
    overflows (CVE-2008-1768).</li>
    <li>Drew Yao finally discovered and a
    boundary error in Cinepak, which might lead to memory corruption
    (CVE-2008-1769).</li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted media
    file or stream, possibly resulting in the remote execution of arbitrary
    code.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All VLC users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-video/vlc-0.8.6f"</code>
  </resolution>
