This script is Copyright (C) 2010-2017 Tenable Network Security, Inc.

Synopsis :

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

Description :

Updated dhcp packages that fix one security issue are now available
for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link 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. DHCPv6 is the DHCP protocol version for IPv6

A NULL pointer dereference flaw was discovered in the way the dhcpd
daemon parsed DHCPv6 packets. A remote attacker could use this flaw to
crash dhcpd via a specially crafted DHCPv6 packet, if dhcpd was
running as a DHCPv6 server. (CVE-2010-3611)

Users running dhcpd as a DHCPv6 server should upgrade to these updated
packages, which contain a backported patch to correct this issue.
After installing this update, all DHCP servers will be restarted
