An attacker who successfully exploited the vulnerability could cause the DHCP server service to stop responding. To exploit the vulnerability, a remote unauthenticated attacker could send a specially crafted packet to an affected DHCP server. The security update addresses the vulnerability by correcting how DHCP servers handle network packets.
