Does anyone have any ideas what kind of actual attack could take advantage of this? The attacker can only cause you to install your keys early once per key phase change. Assuming you hardly every change key phase, what then? I agree it's a way the unauthenticated attacker can change your state, but I don't think it's a big enough problem we need to worry about fixing.
