			SCO Security Advisory

Subject:		OpenLinux: cups denial of service vulnerability
Advisory number: 	CSSA-2004-012.0
Issue date: 		2004 March 03
Cross reference:	sr887386 fz528509 erg712497 CAN-2003-0788
______________________________________________________________________________


1. Problem Description

	Unknown vulnerability in the Internet Printing Protocol (IPP)
	implementation in CUPS before 1.1.19 allows remote attackers to
	cause a denial of service via certain inputs to the IPP port. 

	The Common Vulnerabilities and Exposures project (cve.mitre.org)
	has assigned the name CAN-2003-0788 to this issue.


2. Vulnerable Supported Versions

	System				Package
	----------------------------------------------------------------------
	OpenLinux 3.1.1 Server		prior to cups-1.1.20-1.i386.rpm
					prior to cups-devel-1.1.20-1.i386.rpm
					prior to cups-libs-1.1.20-1.i386.rpm

	OpenLinux 3.1.1 Workstation	prior to cups-1.1.20-1.i386.rpm
					prior to cups-devel-1.1.20-1.i386.rpm
					prior to cups-libs-1.1.20-1.i386.rpm


3. Solution

	The proper solution is to install the latest packages.  This patch 
	obsoletes two cups rpm packages namely cups-client and cups-ppd.  
	These packages need to be removed from the system. 

	To remove cups-client and cups-ppd from your system, as the root 
	user issue the following commands:

	#rpm -e cups-client
	#rpm -e cups-ppd

	Note: Warning messages about directories not removed is expected.
	
	After the two obsoleted packages are removed, you can install the 
	updated packages manually or use the Caldera System Updater, 
	called cupdate (or kcupdate under the KDE environment).
