I've just realised that there's a problem with SSL with disabled encryption on a unix socket / localhost connections for cpu-saving. Any local user using this attack would be able to eavesdrop everything comming through a socket. If an attacker just acts as a tunnel, highjacking a unix-socket and talking to a server using any other interface (or the other way around), then he would not be able to modify information flow, but he would be able to read and save everything going to and from a server. It is again not obvious as normally local connections are not susceptible to eavesdropping. And could go unnoticed for a long time as everything would just work normally. So I think no cpu-saving by turning off encryption should be done. And this would all not help for a denial-of-service attack.
