Amazon Linux AMI : dhcp (ALAS-2013-157)

High Nessus Plugin ID 69716

Synopsis

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

Description

A flaw was found in the way the dhcpd daemon handled the expiration time of IPv6 leases. If dhcpd's configuration was changed to reduce the default IPv6 lease time, lease renewal requests for previously assigned leases could cause dhcpd to crash. (CVE-2012-3955)

Solution

Run 'yum update dhcp' to update your system.
