    Package        : libvirt
    CVE ID         : CVE-2016-5008
    
    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".
    
    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.
