The Dynamic Host Configuration 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.
Two denial of service flaws were found in the way the dhcpd daemon handled
certain incomplete request packets. A remote attacker could use these flaws
to crash dhcpd via a specially-crafted request. (CVE-2011-2748,
CVE-2011-2749)
Users of DHCP should upgrade to these updated packages, which contain a
backported patch to correct these issues. After installing this update, all
DHCP servers will be restarted automatically.
