  <synopsis>
    MPlayer is vulnerable to integer overflows in FFmpeg and ASF decoding that
    could potentially result in the execution of arbitrary code.

    <p>
    MPlayer is a media player capable of handling multiple multimedia file
    formats.
    </p>
  </background>
  <description>
    <p>
    MPlayer makes use of the FFmpeg library, which is vulnerable to a heap
    overflow in the avcodec_default_get_buffer() function discovered by
    Simon Kilvington (see GLSA 200601-06). Furthermore, AFI Security
    Research discovered two integer overflows in ASF file format decoding,
    in the new_demux_packet() function from libmpdemux/demuxer.h and the
    demux_asf_read_packet() function from libmpdemux/demux_asf.c.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could craft a malicious media file which, when opened using
    MPlayer, would lead to a heap-based buffer overflow. This could result
    in the execution of arbitrary code with the permissions of the user
    running MPlayer.
    </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 &quot;&gt;=media-video/mplayer-1.0.20060217&quot;</code>
