			SCO Security Advisory

Subject:		OpenLinux: mc Updated packages resolve local buffer overflow vulnerability
Advisory number: 	CSSA-2004-014.0
Issue date: 		2004 March 25
Cross reference:	sr889551 fz528937 erg712553 CAN-2003-1023
______________________________________________________________________________


1. Problem Description

	Stack-based buffer overflow in vfs_s_resolve_symlink of
	vfs/direntry.c for Midnight Commander (mc) 4.6.0 and earlier,
	and possibly later versions, allows remote attackers to
	execute arbitrary code during symlink conversion. 

	The Common Vulnerabilities and Exposures project (cve.mitre.org) 
	has assigned the name CAN-2003-1023 to this issue.


2. Vulnerable Supported Versions

	System				Package
	----------------------------------------------------------------------
	OpenLinux 3.1.1 Server		prior to mc-4.5.51-6.i386.rpm
					prior to mc-doc-4.5.51-6.i386.rpm

	OpenLinux 3.1.1 Workstation	prior to mc-4.5.51-6.i386.rpm
					prior to mc-doc-4.5.51-6.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.
