Microsoft Windows Vista DHCP denial of service

win-vista-dhcp-dos (40098) The risk level is classified as LowLow 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.

Platforms Affected:

  • Microsoft, Windows Vista x64
  • Microsoft, Windows Vista

Remedy:

Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS08-004. See References.
