Synopsis

The remote Red Hat host is missing a security update.

Description

An updated dhcp package that corrects a security flaw is now available for Red Hat Enterprise Linux 2.1.

This update has been rated as having important security impact by the Red Hat Security Response Team.

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 validates certain DHCP protocol options. A malicious DHCP client could send a carefully crafted DHCP request and cause dhcpd to crash or possibly execute arbitrary code.
(CVE-2007-5365)

All users of dhcp should upgrade to this updated package, which contains a backported patch that resolves this issue.

Solution

Update the affected dhcp package.
