			SCO Security Advisory

Subject:		Linux: tcpdump denial-of-service in print-bgp.c 
Advisory number: 	CSSA-2002-050.0
Issue date: 		2002 November 19
Cross reference:
______________________________________________________________________________


1. Problem Description

	There is a miscalculation in the use of the sizeof operator in
	tcpdump, allowing, at the least, a denial-of-service attack.


2. Vulnerable Supported Versions

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

	OpenLinux 3.1.1 Server		prior to tcpdump-3.6.2-4.i386.rpm

	OpenLinux 3.1.1 Workstation	prior to tcpdump-3.6.2-4.i386.rpm

	OpenLinux 3.1 Server		prior to tcpdump-3.6.2-4.i386.rpm

	OpenLinux 3.1 Workstation	prior to tcpdump-3.6.2-4.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.
