Amazon Linux AMI : gnupg2 Remote Attack Vulnerability (ALAS-2013-237)

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

Synopsis :

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

Description :

GnuPG: infinite recursion in the compressed packet parser DoS

GnuPG 1.4.x, 2.0.x, and 2.1.x treats a key flags subpacket with all
bits cleared (no usage permitted) as if it has all bits set (all usage
permitted), which might allow remote attackers to bypass intended
cryptographic protection mechanisms by leveraging the subkey.
