An Achilles' Heel in version 5.0 of the Sygate Personal Firewall allows spoofing which could allow an enemy of your PC to attack the host machine by using the 127.0.0.1 Internet Protocol (IP) address, the report said.
Sygate has recognised there is a problem for the Windows based software and will issue a patch to fix the problem as soon as possible.
The severity rank of the problem is rated as "high", as it allows "any form of attack" on a host PC.
