Scientific Linux Security Update : dhcp on SL5.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.

A denial of service flaw was found in the way the dhcpd daemon handled
zero-length client identifiers. A remote attacker could use this flaw
to send a specially crafted request to dhcpd, possibly causing it to
enter an infinite loop and consume an excessive amount of CPU time.
(CVE-2012-3571)

Users of DHCP 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 automatically.
