> Happily, not one of those bugs could actually be escalated into an actual exploit. In each case, Rust's various runtime checks successfully caught the problem and turned it into a controlled panic. This has been more or less our experience with fuzzing rust code in firefox too, fwiw. Fuzzing found a lot of panics (and debug assertions / "safe" overflow assertions). In one case it actually found a bug that had been under the radar in the analogous Gecko code for around a decade.
