traffic." );

"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." );
