Summary Incorrect temporary file usage The ruby_parser Gem does not create temporary files securely. In the `diff_pp` function contained in `lib/gauntlet_rubyparser.rb` function, it creates files as `/tmp/a.[pid]` and `/tmp/b.[pid]` which can be predicted and used for either a denial of service (file cannot be overwritten), or to change the contents of files that are writable.
