Synopsis
A virtualization application installed on the remote Windows host is affected by multiple vulnerabilities
Description
The version of VMware Workstation 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 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.
Solution
Upgrade to VMware Workstation version 12.5.9 / 14.1.1 or later.
