  <description>
    <p>
    Florian Westphal discovered a buffer overflow caused by an integer
    underflow in the Lists_MakeMask() function of lists.c.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker can exploit this buffer overflow to crash the ngIRCd
    daemon and possibly execute arbitrary code with the rights of the
    ngIRCd daemon process.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All ngIRCd users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-irc/ngIRCd-0.8.2&quot;</code>
  </resolution>
