Red Hat Security Advisory 2012-1140-01 - The Dynamic Host Configuration Protocol 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. A denial of service flaw was found in the way the dhcpd daemon handled zero-length client identifiers.

Upstream acknowledges Markus Hietava of the Codenomicon CROSS project as the original reporter of this issue.
