Mac OS X : OS X Server < 5.0.15 Multiple Vulnerabilities

medium Nessus Plugin ID 86604

Language:

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 5.0.15. It is, therefore, affected by the following vulnerabilities :

- A denial of service vulnerability exists due to an assertion flaw that is triggered when parsing malformed DNSSEC keys. An unauthenticated, remote attacker can exploit this, via a specially crafted query to a zone containing such a key, to cause a validating resolver to exit. (CVE-2015-5722)

- A denial of service vulnerability exists in the fromwire_openpgpkey() function in openpgpkey_61.c that is triggered when the length of data is less than 1. An unauthenticated, remote attacker can exploit this, via a specially crafted response to a query, to cause an assertion failure that terminates named. (CVE-2015-5986)

- A flaw exists in the web service component due to HTTP header field references missing from configuration files.
A remote attacker can exploit this to bypass access restrictions. (CVE-2015-7031)

Solution

Upgrade to Mac OS X Server version 5.0.15 or later.

Note that OS X Server 5.0.15 is available only for OS X 10.10.5 and OS X 10.11.1 or later.
