Description: Kostya Kortchinsky has reported two vulnerabilities in Microsoft Windows NT, allowing malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system. 1) The vulnerability is caused due to an unchecked buffer during logging of a certain value from specific network packets. This can be exploited to cause the DHCP service to stop responding. 2) The vulnerability is caused due to an unchecked buffer in the handling of DHCP request traffic. This can be exploited to cause a buffer overflow and allow execution of arbitrary code. Solution: Apply patches.
