Description Petr Matousek 2013-12-10 06:48:14 UTC 
By default, remote-viewer first connects to insecure port and only switches to TLS when server requests/requires it when native spice client invocation method is used. An attacker on client local machine or on the router on the way can easily set up a MITM Evil Proxy that would pretend to be endpoint of plaintext port from client POV and it would act as a regular client to the server.
