Mac OS X Multiple Vulnerabilities (Security Updates 2016-003 / 2016-007)

high Nessus Plugin ID 95918

Synopsis

The remote host is missing a Mac OS X update that fixes multiple security vulnerabilities.

Description

The remote host is running a version of Mac OS X 10.10.5 or 10.11.6 that is missing a security update. It is therefore, affected by multiple vulnerabilities :

- A denial of service vulnerability exists in the ssl_parse_clienthello_tlsext() function within file ssl/t1_lib.c when handling oversize OCSP Status Request extensions from clients. An unauthenticated, remote attacker can exploit this to cause memory exhaustion in a process linked with the library. (CVE-2016-6304)

- A memory corruption issue exists in Bluetooth due to improper validation of user-supplied input. A local attacker can exploit this, via a specially crafted application, to cause a denial of service condition or the execution of arbitrary code with kernel level privileges. (CVE-2016-7596)

- A NULL pointer dereference flaw exists in the CoreCapture component due to improper validation of user-supplied input. A local attacker can exploit this to cause a denial of service condition. (CVE-2016-7604)

Solution

Install Security Update 2016-007 (OS X 10.10.5) / 2016-003 (OS X 10.11.6) or later.
