Description

A remote overflow exists in Kerio Personal Firewall (KPF). The KPF fails to check the boundary of handshake packets in the administration authentication process. By sending a specially crafted request during the handshake process to establish a connection to the administration port, a remote attacker can overflow a buffer and execute arbitrary code on the system with the privileges of the Kerio firewall, resulting in a loss of integrity.
