Oracle Linux 4 / 5 / 6 : dhcp (ELSA-2011-1160)

This script is Copyright (C) 2013-2016 Tenable Network Security, Inc.

Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2011:1160 :

Updated dhcp packages that fix two security issues are now available
for Red Hat Enterprise Linux 4, 5, and 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

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.

Two denial of service flaws were found in the way the dhcpd daemon
handled certain incomplete request packets. A remote attacker could
use these flaws to crash dhcpd via a specially crafted request.
(CVE-2011-2748, CVE-2011-2749)

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