When Tony reported on the release of new VMware patches on April 4th, we didn't immediately spot that the same day there was also a release of a for-pay exploit against CVE-2009-1244 (announced in VMSA-2009-0006). Seems a few days later, there is also a white paper available -for pay as well-, and now also a flash video of the alleged exploit showing a XP client OS exploiting a Vista host OS (launching calc.exe). The video also comments that they get a data leak back from the host to the client (hard to tell, all you see is a number of pixels being mangled on the screen). The consequences of this are important. Virtualisation is often used just to consolidate different functions on a shared hardware, and I've seen great uses of it to e.g. be able to continue to run an accounting package that needed an OS that would not run anymore on modern hardware. I've also seen great uses where they cloned images of machines in order to let users have access to archived machines, and then remove the clone after use in order to preserve integrity of such systems. But there are more risky uses:
