Description:
Piotr Bania has reported a weakness in Kerio Personal/ServerFirewall, which can be exploited by malicious, local users to cause a DoS (Denial of Service).
The weakness is caused due to missing validation checks in the FWDRV driver before reading the PEB (Process Environment Block) of a process. This can be exploited to crash the system via a malicious application that locks the memory page where its PEB resides before connecting to the network.
The weakness has been reported in versions:
* Kerio Personal Firewall version 4.2.0 and prior.
* Kerio ServerFirewall version 1.1.1 and prior.
