Subject:		Linux: wwwoffled remote access vulnerability 
Advisory number: 	CSSA-2002-048.0
Issue date: 		2002 November 18
Cross reference:
______________________________________________________________________________


1. Problem Description

	wwwoffled allows remote attackers to cause a denial of service
	and possibly execute arbitrary code via a negative Content-Length
	value.


2. Vulnerable Supported Versions

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

	OpenLinux 3.1.1 Workstation	prior to wwwoffle-2.6b-3MR.i386.rpm

	OpenLinux 3.1 Workstation	prior to wwwoffle-2.6b-3MR.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
