ZoneAlarm Personal Firewall UDP Source Port 67 Bypass

This script is Copyright (C) 2004-2011 Tenable Network Security, Inc.


Synopsis :

This host is running a firewall that fails to filter certain types of
traffic.

Description :

This version of ZoneAlarm contains a flaw that may allow a remote
attacker to bypass the ruleset. The issue is due to ZoneAlarm not
monitoring and alerting UDP traffic with a source port of 67.

This allows an attacker to bypass the firewall to reach protected
hosts without setting off warnings on the firewall.
