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


Synopsis :

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

Description :

The ssl.match_hostname function in the SSL module in Python 2.6
through 3.4 does not properly handle a '\0' character in a domain name
in the Subject Alternative Name field of an X.509 certificate, which
allows man-in-the-middle attackers to spoof arbitrary SSL servers via
a crafted certificate issued by a legitimate Certification Authority,
a related issue to CVE-2009-2408. (CVE-2013-4238)
