FINAL RESULTS:

data/jpegjudge-0.0.2/judge.c:158:15:  [3] (buffer) getopt:
  Some older implementations do not protect against internal buffer overflows
  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
      switch (getopt (argc, argv, "hVb"))
data/jpegjudge-0.0.2/judge.c:52:25:  [2] (misc) fopen:
  Check when opening files - can an attacker redirect it (via symlinks),
  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
      if ((input_file = fopen (filename, "rb")) == NULL)
