    <p>
    oCERT reported that the Speex library does not properly validate the
    "mode" value it derives from Speex streams, allowing for array indexing
    vulnerabilities inside multiple player applications. Within Gentoo,
    xine-lib, VLC, gst-plugins-speex from the GStreamer Good Plug-ins,
    vorbis-tools, libfishsound, Sweep, SDL_sound, and speexdec were found
    to be vulnerable.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted Speex
    file or network stream with an application listed above. This might
    lead to the execution of arbitrary code with privileges of the user
    playing the file.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Speex users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-libs/speex-1.2_beta3_p2"</code>
  </resolution>
