In addition, with features like improved ASLR, it is often more difficult to exploit a bug on x64 Linux than x86 Linux. While we designed Qubes from the beginning to limit potential attack vectors, we still realize that some of the code running in Dom0, e.g. our GUI daemon or xen-store daemon, however simple, might contain some bugs.
