The only real ways to block this attack would be to "force" the host and VMs to only use certain cores so that they are never running on the same hardware but this would lead to an effective increase in cost as you would not be able to have as many VMs on a given host. If you wanted a "secure" VM then you have to guarantee that it's cores are isolated. Given enough time and some suitably stealthy software everything is potentially open. Yes, it is by no means easy and is a difficult thing to pull off as the VM CPU core could change at whim of the host and the host could happily schedule tasks on different cores as well, but over a long period of time enough information could be leaked to give up a secret key to some important system or account. From host to VM, from VM to host, and from VM to VM. In this way it means that a machine is exploitable in every direction. Starring: James Badge Dale, Emily Mortimer, Bruce Greenwood. When an otherworldly force wreaks havoc on a war-torn European city, an engineer teams up with an elite Special Ops unit to stop it. Then it can use precise timing to watch the caches for particular patterns of access indicative of the host or guest (or other VM) process that it is looking to exploit. 2016 Maturity Rating: TV-14 1h 48m Action. So, because the VM runs in actual CPU hardware and all it needs to do is run a particular loop to "train" the speculative execution engine. In this way, memory belonging to the victim process is leaked to the malicious process. Then by the side-channel, retrieves the value of this memory. In a nutshell, the predictor is coerced to predict a specific branch result (if -> true), that results in asking for an out-of-bound memory access that the victim process would not normally have requested, resulting in incorrect speculative execution. In this attack, the attacker tricks the speculative execution to predictively execute instructions erroneously. Spectre works on a different level and does not allow access to kernel-space data from user-space. Things like qemu can do emulation which would be safer as it is not a hardware CPU, but it is much slower and is different from virtualization.įrom the canonical post again: Virtualization is only fast because it uses the physical CPU with as little abstraction as possible and relies on CPU hardware to provide isolation. It is essentially just another layer within the physical CPU in your system. It uses the same caches and instructions as the host does. VMs use the actual CPU in your system with some privileged instructions trapped and able to be redirected. Spectre works with containers, as containers relies on the host Meltdown attacks do not cross VMs, only leaks kernel memory to local processes.Security.SE has a canonical Q & A regarding this and it mentions VM's: I am running a Virtual Machine/Containers, to what extent am I vulnerable?

Most of the large providers should have been patched against the flaws by now, as best they can be, but this is going to be a problem that lives with us for some time. Most of the news stories on the internet speak about the cloud providers being worst hit by this as they have massive clusters of systems that are virtualised and could potentially be abused to leak sensitive information. The main portion of these rules describes the setup and game play for the 2-3 players.Yes Spectre can cross host/guest, guest/host and guest/guest boundaries because this is a CPU level flaw that means that potentially sensitive information can be leaked across anything that runs on a CPU core.
