    <p>
    The following vulnerabilities have been discovered in Wireshark.
    Firstly, if the IPsec ESP parser is used it is susceptible to
    off-by-one errors, this parser is disabled by default; secondly, the
    SCSI dissector is vulnerable to an unspecified crash; and finally, the
    Q.2931 dissector of the SSCOP payload may use all the available memory
    if a port range is configured. By default, no port ranges are
    configured.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker might be able to exploit these vulnerabilities, resulting
    in a crash or the execution of arbitrary code with the permissions of
    the user running Wireshark, possibly the root user.
    </p>
  </impact>
  <workaround>
    <p>
    Disable the SCSI and Q.2931 dissectors with the "Analyse" and "Enabled
    protocols" menus. Make sure the ESP decryption is disabled, with the
    "Edit -> Preferences -> Protocols -> ESP" menu.
    </p>
  </workaround>
  <resolution>
    <p>
    All Wireshark users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-analyzer/wireshark-0.99.3&quot;</code>
  </resolution>
