Amazon Linux AMI : libxml2 Denial of Service (ALAS-2013-188)

This script is Copyright (C) 2013 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 libxml2 performed string
substitutions when entity values for entity references replacement was
enabled. A remote attacker could provide a specially-crafted XML file
that, when processed by an application linked against libxml2, would
lead to excessive CPU consumption.
