			SCO Security Advisory

Subject:		OpenLinux: mutt remote buffer overflow
Advisory number: 	CSSA-2004-013.0
Issue date: 		2004 March 25
Cross reference:	sr889558 fz528947 erg712561 CAN-2004-0078
______________________________________________________________________________


1. Problem Description

	Buffer overflow in the index menu code for Mutt 1.4.1 and
	earlier allows remote attackers to cause a denial of service and
	possibly execute arbitrary code via certain mail messages. 

	The Common Vulnerabilities and Exposures project (cve.mitre.org)
	has assigned the name CAN-2004-0078 to this issue.


2. Vulnerable Supported Versions

	System				Package
	----------------------------------------------------------------------
	OpenLinux 3.1.1 Server		prior to mutt-1.2.5-13.i386.rpm
	OpenLinux 3.1.1 Workstation	prior to mutt-1.2.5-13.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.
