    CVE ID         : CVE-2017-1000256
    Debian Bug     : 878799
    
    Daniel P. Berrange reported that Libvirt, a virtualisation abstraction
    library, does not properly handle the default_tls_x509_verify (and
    related) parameters in qemu.conf when setting up TLS clients and servers
    in QEMU, resulting in TLS clients for character devices and disk devices
    having verification turned off and ignoring any errors while validating
    the server certificate.
    
    More informations in https://security.libvirt.org/2017/0002.html .
    
    For the stable distribution (stretch), this problem has been fixed in
    version 3.0.0-4+deb9u1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 3.8.0-3.
