    <p>
    Alvaro Martinez Echevarria discovered a hole in the CUPS Internet Printing
    Protocol (IPP) implementation that allows remote attackers to cause CUPS to
    stop listening on the IPP port.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote user with malicious intent can easily cause a denial of service to
    the CUPS daemon by sending a specially-crafted UDP datagram packet to the
    IPP port.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All CUPS users should upgrade to the latest version:
    </p>
    <code>
    # emerge sync

    # emerge -pv "&gt;=net-print/cups-1.1.20-r2"
    # emerge "&gt;=net-print/cups-1.1.20-r2"</code>
  </resolution>
