<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 ">=net-print/cups-1.1.20-r2"
# emerge ">=net-print/cups-1.1.20-r2"</code>
</resolution>
