Title:	Raptor/Novell Weak ISN
Summary:	NOSUMMARY
Description:	Description: The remote host seems to generate Initial Sequence Numbers (ISN) in a weak manner which seems to solely depend on the source and dest port of the TCP packets. An attacker may exploit this flaw to establish spoofed connections to the remote host. The Raptor Firewall and Novell Netware are known to be vulnerable to this flaw, although other network devices may be vulnerable as well. Solution : If you are using a Raptor Firewall, see http://www.symantec.com/techsupp/bulletin/archive/firewall/082002firewall.html Otherwise, contact your vendor for a patch.
