This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

The remote Amazon Linux AMI host is missing a security update.

Description :

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)

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)
