Examining data/rsakeyfind-1.0/rsakeyfind.cpp

FINAL RESULTS:

data/rsakeyfind-1.0/rsakeyfind.cpp:52:5:  [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.
    char tmp[4];
data/rsakeyfind-1.0/rsakeyfind.cpp:121:12:  [2] (misc) open:
  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).
  int fd = open(filename, O_RDONLY);
