Test ID:
Category:Mac OS X Local Security Checks
Title:Apple MacOSX Security Updates(HT208937)-03
Summary:Apple Mac OS X is prone to multiple vulnerabilities.
Apple Mac OS X is prone to multiple vulnerabilities.

Vulnerability Insight:
Multiple flaws exist due to:

- Lazy FP state restore instead of eager save and restore of the state upon a
context switch. Lazy restored states are potentially vulnerable to exploits
where one process may infer register values of other processes through a
speculative execution side channel that infers their value.

- A memory corruption issue due to poor memory handling.

Vulnerability Impact:
Successful exploitation will allow
attackers to disclose sensitive information and gain elevated privileges.

Affected Software/OS:
Apple Mac OS X versions 10.11.x through
10.11.6 build 15G21013, 10.12.x through 10.12.6 build 16G1408 and
10.13.x through 10.13.5

Upgrade to Apple Mac OS X 10.13.6 or later
or apply the appropriate patch for 10.11.x and 10.12.x versions. Please see the references for more information.
