Severity: Normal
Title: CUPS: Denial of service vulnerability
Date: September 20, 2004
Bugs: #64168
ID: 200409-25
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
==========
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"
