tag_insight = "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.

  A denial of service flaw was found in the way the dhcpd daemon handled
  zero-length client identifiers. A remote attacker could use this flaw to
  send a specially-crafted request to dhcpd, possibly causing it to enter an
  infinite loop and consume an excessive amount of CPU time. (CVE-2012-3571)

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

  Users of DHCP should upgrade to these updated packages, which contain a
  backported patch to correct this issue. After installing this update, all
  DHCP servers will be restarted automatically.";

tag_affected = "dhcp on Red Hat Enterprise Linux (v. 5 server)";
tag_solution = "Please Install the Updated Packages.";
