"The version of VMware Player installed on the remote Windows host
is 14.x prior to 14.1.1 or 12.x prior to 12.5.9. 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 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.");
