    <p>
    iDefense Labs have reported a stack-based buffer overflow in the
    cab_unstore() function when processing negative values in .cab files.
    Multiple file descriptor leaks have also been reported in chmunpack.c,
    pdf.c and dblock.c when processing .chm files.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could send a specially crafted CHM file to the
    scanner, possibly resulting in the remote execution of arbitrary code
    with the privileges of the user running ClamAV.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All ClamAV users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-antivirus/clamav-0.90.2&quot;</code>
  </resolution>
