Synopsis
=======
A vulnerability in CUPS allows remote attackers to cause a denial of service when sending a carefully-crafted UDP packet to the IPP port.
Background
=========
The Common UNIX Printing System (CUPS) is a cross-platform print spooler.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-print/cups < 1.1.20-r2 >= 1.1.20-r2
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. This can be caused by sending an empty UDP datagram packet to the IPP port.
Impact
=====
A remote user with malicious intent can easily cause a denial of service to the CUPS daemon.
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"
