Subject:		OpenLinux: file command buffer overflow
Advisory number: 	CSSA-2003-018.0
Issue date: 		2003 April 28
Cross reference:
______________________________________________________________________________


1. Problem Description

	The file command is vulnerable to a buffer overflow when given
	a maliciously crafted binary to examine.


2. Vulnerable Supported Versions

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

	OpenLinux 3.1.1 Server		prior to file-3.28-8.i386.rpm

	OpenLinux 3.1.1 Workstation	prior to file-3.28-8.i386.rpm

	OpenLinux 3.1 Server		prior to file-3.28-8.i386.rpm

	OpenLinux 3.1 Workstation	prior to file-3.28-8.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.
