Description

Background

The Common UNIX Printing System (CUPS) is a cross-platform print spooler.

Description

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

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.

Workaround

There is no known workaround at this time.

Resolution

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"
