FINAL RESULTS:

data/gpw-0.0.19940601/gpw.c:78:9:  [3] (random) drand48:
  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.
		pik = drand48 ();		/* random number [0,1] */
data/gpw-0.0.19940601/gpw.c:113:10:  [3] (random) drand48:
  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.
			pik = drand48 ();
data/gpw-0.0.19940601/gpw.c:48:2:  [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 password[100];			/* buffer to develop a password */
data/gpw-0.0.19940601/gpw.c:60:17:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
		n_passwords = atoi (&argv[1][0]);
data/gpw-0.0.19940601/gpw.c:62:22:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).

data/gpw-0.0.19940601/loadtris.c:46:2:  [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 buf[100];
data/gpw-0.0.19940601/loadtris.c:50:2:  [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 s1[2], s2[2], s3[2];
data/gpw-0.0.19940601/loadtris.c:72:13:  [2] (misc) fopen:
  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).
		if ((fp = fopen (argv[argno], "r")) == NULL) {
