Amazon Linux AMI : gnupg (ALAS-2014-278)

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

GnuPG 1.x before 1.4.16 generates RSA keys using sequences of
introductions with certain patterns that introduce a side channel,
which allows physically proximate attackers to extract RSA keys via a
chosen-ciphertext attack and acoustic cryptanalysis during decryption.
NOTE: applications are not typically expected to protect themselves
from acoustic side-channel attacks, since this is arguably the
responsibility of the physical device. Accordingly, issues of this
type would not normally receive a CVE identifier. However, for this
issue, the developer has specified a security policy in which GnuPG
should offer side-channel resistance, and developer-specified
security-policy violations are within the scope of CVE.
