Description A race condition exists that allows local users to bypass kernel-mode hook handlers and execute dangerous code. This is achieved through certain user-space memory changes during hook-handler execution. The issue is related to a flaw in a protection mechanism for situations where a crafted program has already begun to execute.

Recommendations For PC Tools Firewall Plus version 6.0.0.88, consider disabling the kernel-mode hook handlers as a temporary workaround until a patch is available. Restrict access to user-space memory to minimize the risk of exploitation.
