Mac OS X : OS X Server < 4.1.5 BIND DoS

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote host is missing a security update for OS X Server.

Description :

The remote Mac OS X host has a version of OS X Server installed that
is prior to 4.1.5. It is, therefore, affected by a denial of service
vulnerability due to an assertion flaw that occurs when handling TKEY
queries. A remote attacker can exploit this, via a specially crafted
request, to cause a REQUIRE assertion failure and daemon exit,
resulting in a denial of service condition.

Solution :

Upgrade to OS X Server version 4.1.5 or later.

Note that OS X Server 4.1.5 is available only for OS X 10.10.5 or
later.

Risk factor :

High / CVSS Base Score : 7.8
