Protocol (DHCP) is a protocol that allows individual devices on an IP network to
get their own network configuration information, including an IP address,
a subnet mask, and a broadcast address. The dhcp packages provide a relay agent
and ISC DHCP service required to enable and administer DHCP on a network.

Security Fix(es):

  * It was found that the DHCP daemon did not properly clean up closed OMAPI
connections in certain cases. A remote attacker able to connect to the
OMAPI port could use this flaw to exhaust file descriptors in the DHCP
daemon, leading to a denial of service in the OMAPI functionality.
