    <p>
    FFmpeg is a complete solution to record, convert and stream audio and
    video. gst-plugins-ffmpeg is a FFmpeg based gstreamer plugin which
    includes a vulnerable copy of FFmpeg code. Mplayer is a multimedia
    player which also includes a vulnerable copy of the code.

  <description>
    <p>
    Multiple vulnerabilities were found in FFmpeg:
    </p>
    <ul><li>astrange
    reported a stack-based buffer overflow in the str_read_packet() in
    libavformat/psxstr.c when processing .str files (CVE-2008-3162).</li>
    <li>Multiple buffer overflows in libavformat/utils.c
    (CVE-2008-4866).</li>
    <li>A buffer overflow in libavcodec/dca.c
    (CVE-2008-4867).</li>
    <li>An unspecified vulnerability in the
    avcodec_close() function in libavcodec/utils.c (CVE-2008-4868).</li>
    <li>Unspecified memory leaks (CVE-2008-4869).</li>
    <li>Tobias Klein
    repoerted a NULL pointer dereference due to an integer signedness error
    in the fourxm_read_header() function in libavformat/4xm.c
    (CVE-2009-0385).</li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted media
    file, possibly leading to the execution of arbitrary code with the
    privileges of the user running the application, or a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
