Description

The version of VMware Workstation installed on the remote host is 10.x prior to 10.0.7 or 11.x prior to 11.1.1. It is, therefore, affected by a privilege escalation vulnerability due to a failure to provide a valid discretionary access control list (DACL) pointer for the printproxy.exe process. A local attacker, using thread injection, can exploit this to gain elevated privileges or execute arbitrary code.
