Vulnerability Description	The Internet Software Consortium (ISC) DHCP server is a popular and widely used implementations of the server side of the DHCP protocol. The Dynamic Host Configuration Protocol (DHCP) protocol is used to centrally manage and automate the assignment of IP addresses on a network. A denial of service and a buffer overflow vulnerability has been reported in the ISC DHCP server. Both vulnerabilities involve buffer overflows and allow a denial of service attack to be launched on the vulnerable software. It may also be possible to exploit the vulnerabilities for remote code execution. Successful exploitation of these vulnerabilities would terminate the DHCP server process and result in a denial of service, a memory buffer overflow or a memory access violation.
