Microsoft Windows Vista DHCP denial of service
| win-vista-dhcp-dos (40098) |  Medium Risk |
Description:
Microsoft Windows Vista is vulnerable to a denial of service caused by an error in the Duplicate Address Detection logic used by the Dynamic Host Configuration Protocol (DHCP) server. By creating a malicious DHCP server and assigning identical broadcast IP addresses to multiple hosts, a remote attacker could exploit this vulnerability to cause a vulnerable system to stop responding and automatically reboot once the Duplicate Address Detection logic attempts to remove the duplicate broadcast IP from the IP route table.
