"The version of VMware Workstation installed on the remote host is 11.x
prior to 11.1.2. It is, therefore, affected by a guest privilege
escalation vulnerability in the Shared Folders (HGFS) feature due to
improper validation of user-supplied input. A local attacker can
exploit this to corrupt memory, resulting in an elevation of
privileges.");

Note that VMware Tools in any Windows-based guests that use the Shared
Folders (HGFS) feature must also be updated to completely mitigate the
vulnerability.");
