Description

 ZoneAlarm contains a flaw that may allow a remote attacker to bypass the firewall's access control filtering mechanism. The problem is that the application fails to inspect and block outbound packets generated by alternate protocol stacks, which may allow a remote attacker to bypass outbound filterings by using non-standard TCP packets created with non-Windows protocol adapters resulting in a loss of integrity.
