    <p>
    Hanno boeck reported an error in libclamav/chmunpack.c when processing
    CHM files (CVE-2008-1389). Other unspecified vulnerabilities were also
    reported, including a NULL pointer dereference in libclamav
    (CVE-2008-3912), memory leaks in freshclam/manager.c (CVE-2008-3913),
    and file descriptor leaks in libclamav/others.c and libclamav/sis.c
    (CVE-2008-3914).
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user or automated system to scan a
    specially crafted CHM, possibly resulting in a Denial of Service
    (daemon crash). The other attack vectors mentioned above could also
    result in a Denial of Service.
    </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-0.94&quot;</code>
  </resolution>
