This is some tremendous research, and really well presented. I love it when researchers lay out their methodology and experiments like this.

Oh, and also - given ssh-agent forwarding with openssh, there's a way for a hostile server to get RCE on the client. But really, there's so much in this piece that is fascinating and probably will be useful or lead to more interesting findings later - I highly recommend reading this.
