Amazon Linux AMI : postgresql9 (ALAS-2012-121)

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

Synopsis :

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

Description :

The libxslt support in contrib/xml2 in PostgreSQL 8.3 before 8.3.20,
8.4 before 8.4.13, 9.0 before 9.0.9, and 9.1 before 9.1.5 does not
properly restrict access to files and URLs, which allows remote
authenticated users to modify data, obtain sensitive information, or
trigger outbound traffic to arbitrary external hosts by leveraging (1)
stylesheet commands that are permitted by the libxslt security options
or (2) an xslt_process feature, related to an XML External Entity (aka
XXE) issue.
