Discussion
Kerio Personal Firewall and ServerFirewall Local Denial of Service Vulnerability
Kerio Personal Firewall and ServerFirewall are prone to a local denial of service vulnerability.
Reports indicate that the FWDRV driver does not verify access to memory associated with the Process Environment Block (PEB) of the application. An attacker can trigger fatal exceptions and cause the firewall process to terminate.
A denial of service condition in the firewall can expose computers to further attacks.
