    <p>
    The following vulnerabilities were reported:
    </p>
    <ul>
    <li>
    Multiple buffer overflows in the NCP dissector (CVE-2008-3146).
    </li>
    <li>
    Infinite loop in the NCP dissector (CVE-2008-3932).
    </li>
    <li>
    Invalid read in the tvb_uncompress() function when processing zlib
    compressed data (CVE-2008-3933).
    </li>
    <li>
    Unspecified error when processing Textronix .rf5 files
    (CVE-2008-3934).</li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could exploit these vulnerabilities by sending
    specially crafted packets on a network being monitored by Wireshark or
    by enticing a user to read a malformed packet trace file, causing a
    Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Wireshark users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-analyzer/wireshark-1.0.3"</code>
  </resolution>
