Mac OS X : OS X Server < 4.1.5 BIND DoS

High Nessus Plugin ID 85410

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.
