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

This script is Copyright (C) 2012 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.
