FINAL RESULTS:

data/yorick-imutil-0.5.7/imutil.c:404:3:  [3] (random) srandom:
  This function is not sufficiently random for security-related functions
  such as key and nonce creation (CWE-327). Use a more secure technique for
  acquiring random values.
  srandom();  /* WARNING! this might be platform specific */
