VULHUB ™

ZoneAlarm is a firewall software package designed for Microsoft Windows operating systems. It is distributed and maintained by Zone Labs. ZoneAlarm does not properly handle some types of traffic. When ZoneAlarm is configured to block all traffic, and a Syn flood of 300 or more packets is sent to a host running the vulnerable software, the system becomes unstable. This problem has been reported as leading to a denial of service condition.
