(RHSA-2005:212) dhcp security update

The dhcp package provides the ISC Dynamic Host Configuration Protocol
(DHCP) server and relay agent, dhcpd. DHCP is a protocol that allows
devices to get their own network configuration information from a server.

A bug was found in the way dhcpd logs error messages. A malicious DNS
server could send a carefully crafted DNS reply and cause dhcpd to crash or
possibly execute arbitrary code. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2005-0446 to this issue.

All users of dhcp should upgrade to this updated package, which contains a
backported patch and is not vulnerable to this issue.
