Amazon Linux AMI : gnupg (ALAS-2013-236)

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

Synopsis :

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

Description :

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.

The compressed packet parser in GnuPG 1.4.x before 1.4.15 and 2.0.x
before 2.0.22 allows remote attackers to cause a denial of service
(infinite recursion) via a crafted OpenPGP message.
