2016 Update to "With Forth, Privacy is a joke"

[Dave Britten]

In fairness, this one isn't so much a vulnerability in the data Siri passes back and forth to - and stores on - Apple servers (which is still a very valid concern; I have Siri disabled on my iPhone and iPad), but more an edge case in lock-screen interactivity that's resulted in a loophole. I faintly remember there being a couple other weaknesses like this in the past that didn't rely on Siri for doing weird things with the UI state.
