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

  <description>
    <p>
    Multiple vulnerabilities were found in VLC:
    </p>
    <ul>
    <li>Michal Luczaj
    and Luigi Auriemma reported that VLC contains boundary errors when
    handling subtitles in the ParseMicroDvd(), ParseSSA(), and
    ParseVplayer() functions in the modules/demux/subtitle.c file, allowing
    for a stack-based buffer overflow (CVE-2007-6681).</li>
    <li>The web
    interface listening on port 8080/tcp contains a format string error in
    the httpd_FileCallBack() function in the network/httpd.c file
    (CVE-2007-6682).</li>
    <li>The browser plugin possibly contains an
    argument injection vulnerability (CVE-2007-6683).</li>
    <li>The RSTP
    module triggers a NULL pointer dereference when processing a request
    without a "Transport" parameter (CVE-2007-6684).</li>
    <li>Luigi
    Auriemma and Remi Denis-Courmont found a boundary error in the
    modules/access/rtsp/real_sdpplin.c file when processing SDP data for
    RTSP sessions (CVE-2008-0295) and a vulnerability in the
    libaccess_realrtsp plugin (CVE-2008-0296), possibly resulting in a
    heap-based buffer overflow.</li>
    <li>Felipe Manzano and Anibal Sacco
    (Core Security Technologies) discovered an arbitrary memory overwrite
    vulnerability in VLC's MPEG-4 file format parser (CVE-2008-0984).</li>
    </ul>
  </description>
  <impact type="high">
    <p>
    A remote attacker could send a long subtitle in a file that a user is
    enticed to open, a specially crafted MP4 input file, long SDP data, or
    a specially crafted HTTP request with a "Connection" header value
    containing format specifiers, possibly resulting in the remote
    execution of arbitrary code. Also, a Denial of Service could be caused
    and arbitrary files could be overwritten via the "demuxdump-file"
    option in a filename in a playlist or via an EXTVLCOPT statement in an
    MP3 file.
    </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-0.8.6e"</code>
  </resolution>
