Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

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

Run 'yum update gnutls' to update your system.
