    <p>jbig2dec is a decoder implementation of the JBIG2 image compression
      format.

  </background>
  <description>
    <p>Integer overflow errors have been discovered in the
      jbig2_decode_symbol_dict, jbig2_build_huffman_table, and
      jbig2_image_compose functions of jbig2dec.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker, by enticing a user to open a specially crafted JBIG2
      file using an application linked against jbig2dec, could possibly execute
      arbitrary code with the privileges of the process or cause a Denial of
      Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All jbig2dec users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=media-libs/jbig2dec-0.13-r4"
    </code>
