FINAL RESULTS:

data/bruteforce-salted-openssl-1.4.2/src/bruteforce-salted-openssl.c:845:14:  [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.

data/bruteforce-salted-openssl-1.4.2/src/bruteforce-salted-openssl.c:84:10:  [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.
