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.

The Mandriva Linux Engineering Team discovered a stack-based buffer
overflow flaw in the ISC DHCP client. If the DHCP client were to receive a
malicious DHCP response, it could crash or execute arbitrary code with the
permissions of the client (root). (CVE-2009-0692)

Users of DHCP should upgrade to these updated packages, which contain a
backported patch to correct this issue.
