Details

Neil Wilson discovered that if VNC passwords were blank in QEMU
configurations, access to VNC sessions was allowed without a password
instead of being disabled. A remote attacker could connect to running
VNC sessions of QEMU and directly control the system. By default, QEMU
does not start VNC sessions.
