Sorry, I didn't mean to suggest we should abandon the change/bug, as not
all distros have crypto policy support systemwide.

Rather, that we should

1. make sure the out of the box behaviour is to honour openssl defaults
2. provide a nova.conf setting for the protocol version, which allows an 
ordered list of versions to be set by the admin. eg might set something like  
vnc_tls_protocol = [ "tls1.3", "tls1.2"]

  Ssl2/3 should not be used for secure VNC access

Status in OpenStack Compute (nova):

Bug description:
  This report is based on Bandit scanner results.


  137 wrapped_sock = ssl.wrap_socket(

  wrap_socket is used without ssl_version that means SSLv23 by default.
  As server part (QEMU) is based on gnutls supporting all modern TLS versions
  it is possible to use stricter tls version on the client (TLSv1.2).
  Another option is to make this param configurable.
