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

medium Nessus Plugin ID 70898

Language:

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.

Solution

Run 'yum update gnupg' to update your system.
