CVE-2013-2016

A flaw was found in the way qemu v1.3.0 and later (virtio-rng) validates
addresses when guest accesses the config space of a virtio device. If the
virtio device has zero/small sized config space, such as virtio-rng, a
privileged guest user could use this flaw to access the matching host’s
qemu address space and thus increase their privileges on the host.
