Scientific Linux Security Update : gnupg on SL5.x i386/x86_64

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)

A denial of service flaw was found in the way GnuPG parsed certain
compressed OpenPGP packets. An attacker could use this flaw to send
specially crafted input data to GnuPG, making GnuPG enter an infinite
loop when parsing data. (CVE-2013-4402)

It was found that importing a corrupted public key into a GnuPG
keyring database corrupted that keyring. An attacker could use this
flaw to trick a local user into importing a specially crafted public
key into their keyring database, causing the keyring to be corrupted
and preventing its further use. (CVE-2012-6085)

It was found that GnuPG did not properly interpret the key flags in a
PGP key packet. GPG could accept a key for uses not indicated by its
holder. (CVE-2013-4351)
