Oracle Linux 6 : gnutls (ELSA-2017-0574)

High Nessus Plugin ID 99063


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


From Red Hat Security Advisory 2017:0574 :

An update for gnutls is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The gnutls packages provide the GNU Transport Layer Security (GnuTLS) library, which implements cryptographic algorithms and protocols such as SSL, TLS, and DTLS.

The following packages have been upgraded to a later upstream version:
gnutls (2.12.23). (BZ#1321112, BZ#1326073, BZ#1415682, BZ#1326389)

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)
