privilege escalation vulnerability.");

"The VMware Workstation installation detected on the remote host is
8.x earlier than 8.0.2 and thus is potentially affected by a local 
privilege escalation vulnerability because the access control list of
the VMware Tools folder is incorrectly set.

By exploiting this issue, a local attacker could elevate his privileges
on Windows-based Guest Operating Systems.");

In addition to patching, VMware Tools must be updated on all non-
