"Vivian Zhang and Christoph Anton Mitterer discovered that setting an
empty VNC password does not work as documented in Libvirt, a
virtualisation abstraction library. When the password on a VNC server
is set to the empty string, authentication on the VNC server will be
disabled, allowing any user to connect, despite the documentation
declaring that setting an empty password for the VNC server prevents
all client connections. With this update the behaviour is enforced by
setting the password expiration to 'now'."
