Comment: This is an exploit for virtual servers (Score 5, Informative) 393

by ashmodai9 (#27678425) Attached to: Intel Cache Poisoning Is Dangerously Easy On Linux

As many have pointed out, there's no real point to "exploiting" a machine that you already have full (root) access to - with one exception: virtual servers.

The whole 'danger' of this exploit is that it enables a virtual server's "privileged" "root" user to gain hypervisor access, which is equivalent to taking over the entire physical machine and any/all other virtual servers hosted on said machine.

If you don't run a virtual server farm, this exploit means absolutely nothing to you. If you do, it's a very easy, scary way whereby any of your "clients" can take over your physical machines and access all of the other virtual servers hosted on the same piece of hardware.

Avoid strange women and temporary variables.
