Interesting that the case they were using was the Nuclear Threat Initiative and FP uncertainties, I've audited some, ah, nuclear-physics-related code that had an issue due to FP uncertainties...

Where you can encode an entire Command and Control server within rounding errors! You sneaky skunk!
It was actually due to the original developer assuming FP compares were exact. It was never an issue, the code went through huge amounts of auditing and testing, just an interesting coincidence that the underhanded contest used something so similar to its underhandedness.
All software is, eventually, rounding error.
