Yes, apparently Schrödinger’s cat is alive, as the latest release of Fedora — Fedora 19, codename Schrödinger’s cat– as been released on July 2nd, and that even happened quite on time. So, apparently, putting the cat “in a box” and all the stuff was way too easy, and that’s why we are bringing the challenge to the next level: do you dare putting Schrödinger’s cat “in a virtual box”?
In other words, do you dare install Fedora 19 within a Xen virtual machine? And if yes, how about doing that using Fedora 19 itself as Dom0?
As many of you might have (inevitably) noticed, Xen frontend / backend network drivers in Linux suffered from regression several months back after the XSA-39 fix (various reports here, here…

The Xen Security team recently disclosed a vulnerability, Xen Security Advisory 7 (CVE-2012-0217), which would allow guest administrators to escalate to hypervisor-level privileges. The impact is much wider than Xen; many other operating systems seem to have the same vulnerability, including NetBSD, FreeBSD, some versions of Microsoft Windows (including Windows 7), and possibly Apple OSX.
So what was the vulnerability? It has to do with a subtle difference in the way in which Intel processors implement error handling in their version of AMD’s SYSRET instruction. The SYSRET instruction is part of the x86-64 standard defined by AMD. If an operating system is written according to AMD’s spec, but run on Intel hardware, the difference in implementation can be exploited by an attacker to write to arbitrary addresses in the operating system’s memory. This blog will explore the technical details of the vulnerability.
This is a guest blog post by Patrick F. Wilbur, a long-time Xen user and active member of the Xen community. You might know me from Xen Day and Xen…
