While VNC password auth is quite limited (literally - to 8 characters :-)) it's still much better than just having an open VNC server. For example considering uppercase + lowercase + numbers (not even symbols) we would get a ~48 bit key which should hold up causal bruteforcers. > Anyone who actually wants credible real world security should be using > the TLS and/or SASL options to VNC, never the awful legacy passwd based > auth. > Agreed. The target of this patch is however not people who know that they want security, but rather people who don't know it :-). Ie. people who just run things with their default settings and stop as soon as it seems to work, without conideration for security.
