Well it concerns vCenter Server only, most people aren't vulnerable. Fortunately most exploits aren't critical to common user, plus most of them are on vmware, I believe people often use VirtualBox.
Using virtualization to "prevent exploitation of the host" is still quite safe (but never 100% safe obviously) for a standard user

That's the only saving grace, really. Standard user will not be using vCenter, so poor life decisions will have no impact.
