Scientific Linux Security Update : gnutls on SL6.x i386/x86_64

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

The following packages have been upgraded to a later upstream version:
gnutls (2.12.23).

Security Fix(es) :

- A denial of service flaw was found in the way the
TLS/SSL protocol defined processing of ALERT packets
during a connection handshake. A remote attacker could
use this flaw to make a TLS/SSL server consume an
excessive amount of CPU and fail to accept connections
form other clients. (CVE-2016-8610)

- Multiple flaws were found in the way gnutls processed
OpenPGP certificates. An attacker could create specially
crafted OpenPGP certificates which, when parsed by
gnutls, would cause it to crash. (CVE-2017-5335,
CVE-2017-5336, CVE-2017-5337)
