  <description>
    <p>
    Multiple vulnerabilities have been reported in UnrealIRCd:
    </p>
    <ul>
    <li>The vendor reported a buffer overflow in the user authorization
    code (CVE-2009-4893).</li>
    <li>The vendor reported that the distributed source code of UnrealIRCd
    was compromised and altered to include a system() call that could be
    called with arbitrary user input (CVE-2010-2075).</li>
    </ul>
  </description>
  <impact type="high">
    <p>
    A remote attacker could exploit these vulnerabilities to cause the
    execution of arbitrary commands with the privileges of the user running
    UnrealIRCd, or a Denial of Service condition. NOTE: By default
    UnrealIRCd on Gentoo is run with the privileges of the "unrealircd"
    user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All UnrealIRCd users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-irc/unrealircd-3.2.8.1-r1&quot;</code>
  </resolution>
