			SCO Security Advisory

Subject:		OpenLinux: vim arbitrary commands execution through modelines
Advisory number: 	CSSA-2004-015.0
Issue date: 		2004 March 30
Cross reference:	sr889557 fz528946 erg712560 CAN-2002-1377
______________________________________________________________________________


1. Problem Description

	vim 6.0 and 6.1, and possibly other versions, allows attackers
	to execute arbitrary commands using the libcall feature in
	modelines, which are not sandboxed but may be executed when
	vim is used as an editor for other products such as mutt. 
	
	The Common Vulnerabilities and Exposures project (cve.mitre.org)
	has assigned the name CAN-2002-1377 to this issue.


2. Vulnerable Supported Versions

	System				Package
	----------------------------------------------------------------------
	OpenLinux 3.1.1 Server		prior to vim-6.2-1.i386.rpm
					prior to vim-X11-6.2-1.i386.rpm
					prior to vim-help-6.2-1.i386.rpm
					prior to vim-i18n-6.2-1.i386.rpm

	OpenLinux 3.1.1 Workstation	prior to vim-6.2-1.i386.rpm
					prior to vim-X11-6.2-1.i386.rpm
					prior to vim-help-6.2-1.i386.rpm
					prior to vim-i18n-6.2-1.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.
