<title>CUPS: Denial of service vulnerability</title>
A vulnerability in CUPS allows remote attackers to cause a denial of
service when sending a carefully-crafted UDP packet to the IPP port.

<package name="net-print/cups" auto="yes" arch="*">

<vulnerable range="lt">1.1.20-r2</vulnerable>
The Common UNIX Printing System (CUPS) is a cross-platform print spooler.
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.
<impact type="normal">
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.
There is no known workaround at this time.
All CUPS users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=net-print/cups-1.1.20-r2"
# emerge ">=net-print/cups-1.1.20-r2"</code>
