[GTALUG] python sweetness — The mysterious case of the Linux Page Table

One could assert that the days of time sharing systems are largely over,
at least on production systems that people care about.

And I think it's fair to say that it has been good practice for quite
some time to not allow random binaries to run on systems you care about.

I have no idea whether hypervisors (like xen or esxi) are vulnerable.
But the same guidelines can be applied to VMs running on hypervisors.

I wonder how exploitable this problem really is?

Cheers, happy new year
