VULHUB ™

A vulnerability is reported to affect the Sygate Personal Firewall fail-closed functionality. It is reported that the kernel-space NDIS driver does not verify the origin of messages that are received through the associated device. As a result of this it is possible for a local user to transmit a message to the kernel-space NDIS driver device in order to disable the firewall fail-closed functionality. A local attacker may exploit this condition to disable the affected firewall completely.
