possibly escalate their privileges. In the default installation, when QEMU
is used with libvirt, attackers would be isolated by the libvirt AppArmor
profile. (CVE-2016-9602)
Gerd Hoffmann discovered that QEMU incorrectly handled the Cirrus VGA
device when being used with a VNC connection. A privileged attacker inside
the guest could use this issue to cause QEMU to crash, resulting in a
