Hi, I implemented some suggestions in a PR against this PR: blackheaven#2
As explained there, the original motivation was a function to query advisories for a specific version, but I got a bit carried away and changed some more stuff. As mentioned there, feel free to use it as a whole or cherry-pick the parts you like. While some of the changes are not really important there is one I'd like to see included here: IMHO listAffectedBy (or listVersionRangeAffectedBy in my PR - I renamed it) should not use exitFailure as it makes it more difficult to work with this function if you use hsec-tools as library.
