Description

ISC reports:

A bug exists which allows an attacker who is able to send DHCP Request packets, either directly or through a relay, to remotely crash an ISC DHCP server if that server is configured to evaluate expressions using a regular expression (i.e. uses the "~=" or "~~" comparison operators).
