FINAL RESULTS:

data/r-cran-luminescence-0.9.8/src/create_UID.cpp:19:19:  [3] (random) random:
  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.

data/r-cran-luminescence-0.9.8/src/create_UID.cpp:22:3:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
