FINAL RESULTS:

data/ruby-curses-1.2.4/ext/curses/curses.c:737:5:  [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 rtn[GETSTR_BUF_SIZE];

data/ruby-curses-1.2.4/ext/curses/curses.c:3969:6:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
	    sprintf(c, "KEY_F%d", i);
data/ruby-curses-1.2.4/ext/curses/curses.c:3971:6:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
	    sprintf(c, "F%d", i);
data/ruby-curses-1.2.4/ext/curses/curses.c:741:46:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
    return rb_external_str_new_with_enc(rtn, strlen(rtn), keyboard_encoding);
data/ruby-curses-1.2.4/ext/curses/curses.c:2246:50:  [1] (buffer) strlen:

  perform an over-read (it could cause a crash if unprotected) (CWE-126).
