______________________________________________________________________________


1. Problem Description

	gv can be forced to execute arbitrary shell commands by using
	a buffer overflow.


2. Vulnerable Supported Versions

	System				Package
	----------------------------------------------------------------------

	OpenLinux 3.1.1 Server		prior to gv-3.5.8-10.i386.rpm
					prior to gv-doc-html-3.5.8-10.i386.rpm

	OpenLinux 3.1.1 Workstation	prior to gv-3.5.8-10.i386.rpm
					prior to gv-doc-html-3.5.8-10.i386.rpm

	OpenLinux 3.1 Server		prior to gv-3.5.8-10.i386.rpm
					prior to gv-doc-html-3.5.8-10.i386.rpm

	OpenLinux 3.1 Workstation	prior to gv-3.5.8-10.i386.rpm
					prior to gv-doc-html-3.5.8-10.i386.rpm


3. Solution

	The proper solution is to install the latest packages. Many
	customers find it easier to 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.
