FINAL RESULTS:

data/forensics-colorize-1.1/src/ui.c:10:5:  [4] (format) vfprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.

  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
