Amazon Linux AMI : libxml2 (ALAS-2012-52)

This script is Copyright (C) 2013-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

It was found that the hashing routine used by libxml2 arrays was
susceptible to predictable hash collisions. Sending a specially
crafted message to an XML service could result in longer processing
time, which could lead to a denial of service. To mitigate this issue,
randomization has been added to the hashing function to reduce the
chance of an attacker successfully causing intentional collisions.
