badpack3t has reported a vulnerability in Windows, which can be exploited by malicious people to cause a DoS (Denial of Service). The vulnerability is caused due to an unspecified error in the kernel and can be exploited to cause the system to crash. Reportedly, the integrated firewall does not protect against this.

The vulnerability has been reported in Windows XP SP2.

Solution: Restrict incoming traffic to affected systems to reduce the risk.

The vendor is reportedly working on a patch, which will be released in August.
