+    qemu: ensure TLS clients always verify the server certificate
+    
+    The default_tls_x509_verify (and related) parameters in qemu.conf
+    control whether the QEMU TLS servers request & verify certificates
+    from clients. This works as a simple access control system for
+    servers by requiring the CA to issue certs to permitted clients.
+    This use of client certificates is disabled by default, since it
+    requires extra work to issue client certificates.
+    
+    Unfortunately the code was using this configuration parameter when
+    setting up both TLS clients and servers in QEMU. The result was that
+    TLS clients for character devices and disk devices had verification
+    turned off, meaning they would ignore errors while validating the
+    server certificate.
+    
+    This allows for trivial MITM attacks between client and server,
+    as any certificate returned by the attacker will be accepted by
+    the client.
+    
+    This is assigned CVE-2017-1000256  / LSN-2017-0002
