RHEL 4 : dhcp (RHSA-2009:1136)

This script is Copyright (C) 2009-2014 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated dhcp packages that fix a security issue are now available for
Red Hat Enterprise Linux 4 and 4.7 Extended Update Support.

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

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.
