Subject: Re: VMSA-2011-0008 VMware vCenter Server and
	vSphere Client security vulnerabilities

Hi...
Quick question.

As cloud virtualization becomes an increasingly popular trend now for enterprises companies and VMWare is sought after in most cases to supply the infrastructure, where does VMWare stand from a vulnerability standpoint when it comes to publicized attacks such as Guest Stealer and the vulnerabilities that Metasploit's VASTO module aims to take advantage of.

What I hope to be the case is that VMWare has patched all of the exploits that would make a script-kiddies efforts a waste of time when launching Metasploit and throwing a bunch of exploits from the VASTO module against a VMWare environment.

Forgive me if this is something that has already been discussed or the vulnerability has been plugged.

I do intend on setting up ESXi in my own lab and running some of the VASTO modules, but I figured I would go to the source and bounce the question off a VMWare Security expert.

VASTO guest_stealer Demonstration - just to name one particular payload.

Thanks in advance for your time.
