Although I still have a deep admiration for the Klapötke "Energetic Materials" group at Munich Uni.
I'd like to ask what, other than money directly motivates people? Is it prestige? A line on their resume? A requirement for a bootcamp class? In addition, we should re-evaluate the difficulty of submitting a CVE. Is it too easy? The story about a mass of "hey your regex parser could choke on this weird expression[1]" reports suggest that perhaps so. What can we do to make it so that CVEs and equivalents are truly meaningful? Also, just the fact that CVE reports are given a great deal of respect could be the problem, although at this point that seems to be self-correcting.
[1] Some classes of regex parsers are known to be vulnerable by nature, those that do backtracking for example, because their worst-case runtime grows exponentially and can run in unbounded time. This has been known since at least 2009. There are other implementations with better worst-case runtimes, but worse performance in typical cases. The fact that it's trivially easy to look at a regex parser to see if it does backtracking and construct an "evil" expression that breaks it means it's trivially easy to file a DOS report against any such parser.
