			SCO Security Advisory

Subject:		OpenLinux: util-linux could leak sensitive data
Advisory number: 	CSSA-2004-016.0
Issue date: 		2004 March 30
Cross reference:	sr889555 fz528943 erg712558 CAN-2004-0080
______________________________________________________________________________


1. Problem Description

	The login program in util-linux 2.11 and earlier uses a pointer
	after it has been freed and reallocated, which could cause login
	to leak sensitive data. 

	The Common Vulnerabilities and Exposures project (cve.mitre.org) 
	has assigned the name CAN-2004-0080 to this issue.


2. Vulnerable Supported Versions

	System				Package
	----------------------------------------------------------------------
	OpenLinux 3.1.1 Server		prior to util-linux-2.12-1.i386.rpm
	OpenLinux 3.1.1 Workstation	prior to util-linux-2.12-1.i386.rpm


3. Solution

	The proper solution is to install the latest packages. Unix
	users with Linux Kernel Personality can use the Caldera System
	Updater, called cupdate (or kcupdate under the KDE environment),
	to update these packages rather than downloading and installing
	them by hand.
