@Tim Kelsey: I think the plan is to make the policy configurable, with
auto-add (but fail if changed) as the default, which is secure enough
for most people but can be bumped up by sufficiently paranoid installed
who do the work to collect the keys first.

Title:
  Cinder utils SSHPool should allow customized ssh host keys and missing
  policy

Status in Cinder:
  Fix Released
Status in OpenStack Security Advisories:
  Won't Fix
Status in OpenStack Security Notes:
  In Progress

Bug description:
  In cinder/utils.py, SSHPool is using paramiko.AutoAddPolicy() as
  default. This may lead security issue without being notified. The
  utility should allow customized usage when create the pool or session.
  Also the host_keys file should be allowed to be customized so that any
  driver utilizing the SSHPool should have their customized security
  setting or delegate to customer's scenario & configuration to
  determine the policy and key files.
