New! Plugin Severity Now Using CVSS v3

Synopsis

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

Description

Improper fetch cleanup sequencing in the resolver can cause named to crash :

A use-after-free flaw leading to denial of service was found in the way BIND internally handled cleanup operations on upstream recursion fetch contexts. A remote attacker could potentially use this flaw to make named, acting as a DNSSEC validating resolver, exit unexpectedly with an assertion failure via a specially crafted DNS request.(CVE-2017-3145)

Solution

Run 'yum update bind' to update your system.
