The ISC DHCP server contains a vulnerability that could allow a remote attacker to cause a denial of service.
According to ISC:
If a TCP connection is established to the server on a port which has been configured for communication with a failover peer, this can cause it to become non-responsive to all normal DHCP protocol traffic. The server will progress to a communications-interrupted state - but in addition will also cease to provide DHCP services to clients. The server must be restarted to resume normal operation.
An unauthenticated remote attacker could cause the server to become unresponsive to all normal DHCP protocol traffic, thereby creating a denial of service.
