Scientific Linux Security Update : dhcp on 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

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.

Two memory leak flaws were found in the dhcpd daemon. A remote
attacker could use these flaws to cause dhcpd to exhaust all available
memory by sending a large number of DHCP requests. (CVE-2012-3954)

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