Mac OS X host is 8.x prior to 8.5.10 or 10.x prior to 10.1.1. It is,
therefore, missing security updates that add hypervisor-assisted
guest remediation for a speculative execution vulnerability
(CVE-2017-5715). These updates will allow guest operating
systems to use hardware support for branch target mitigation and
will require guest OS security updates as detailed in VMware
Knowledge Base article 52085.
It is also affected by use-after-free and integer-overflow vulnerabilities.

Note that hypervisor-specific remediation's for this vulnerability
were released as part of VMSA-2018-0002.");
