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.

For the stable distribution (jessie), this problem has been fixed in version 1.2.9-9+deb8u3.

For the unstable distribution (sid), this problem has been fixed in version 2.0.0-1.

We recommend that you upgrade your libvirt packages.");
