Scientific Linux Security Update : dhcp on SL4.x, SL5.x, SL6.x i386/x86_64

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

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.
