Description:
eEye Digital Security has reported a vulnerability in Kerio Personal Firewall, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in "FWDRV.SYS" when performing low level processing of TCP, UDP, and ICMP packets. This can be exploited to consume all available CPU resources by sending a specially crafted packet containing an IP option followed by a length field with the value of "0x00".
Successful exploitation causes the system to stop responding and requires the system to be restarted.
The vulnerability affects versions 4.0.0 through 4.1.1.
