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

High Nessus Plugin ID 99217

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)

Solution

Update the affected packages.
