New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 6


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


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.


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.
