Loads of bugs aren't detected by fuzz testing, as this technique exhibits stochastic behaviour, where you'll most likely find bugs overall, but have varying chances (including none at all) of uncovering specific bugs.

Which is great news for those of us who approach such research by gaining a deep understanding of the code and the systems it exists in, and figuring out vulnerabilities from that perspective. An overreliance on fuzzing keeps us employed.
