Amazon Linux AMI : dhcp (ALAS-2012-115)

This script is Copyright (C) 2013-2015 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.

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)
