One could assert that the days of time sharing systems are largely over, at least on production systems that people care about. And I think it's fair to say that it has been good practice for quite some time to not allow random binaries to run on systems you care about. I have no idea whether hypervisors (like xen or esxi) are vulnerable. But the same guidelines can be applied to VMs running on hypervisors. I wonder how exploitable this problem really is?
