> AFL can fuzz ruby by running ruby on arbitrary inputs. If you're brave (consider "system rm -rf /home") this is worth doing. I recently ran such a fuzzing test against GNU Awk. Unfortunately the bugs I reported are still unfixed, but it didn't take too long to find them, and it was a good learning exercise: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=816271 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=816271 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=816277 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=816277 I'm sure passing "random" input to Perl, Python, Ruby, and many other languages will lead to similar results.
