DHCP: ISC DHCP Server Packet Processing Denial of Service

This signature detects attempts to exploit a known vulnerability against ISC DHCP Server. A successful attack can result in a denial-of-service condition.

Extended Description

The server in ISC DHCP 3.x and 4.x before 4.2.2, 3.1-ESV before 3.1-ESV-R3, and 4.1-ESV before 4.1-ESV-R3 allows remote attackers to cause a denial of service (daemon exit) via a crafted DHCP packet.
