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

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

It was found that GnuPG was vulnerable to the Yarom/Falkner
flush+reload cache side-channel attack on the RSA secret exponent. An
attacker able to execute a process on the logical CPU that shared the
L3 cache with the GnuPG process (such as a different local user or a
user of a KVM guest running on the same host with the kernel same-page
merging functionality enabled) could possibly use this flaw to obtain
portions of the RSA secret key. (CVE-2013-4242)
