FINAL RESULTS:

data/bruteforce-luks-1.3.1/src/bruteforce-luks.c:578:14:  [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.
  while((c = getopt(argc, argv, "b:e:f:hl:m:s:t:v:w:")) != -1)
data/bruteforce-luks-1.3.1/src/bruteforce-luks.c:47:10:  [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.

  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).
