Examining data/enscribe-0.1.0/enscribe.c

FINAL RESULTS:

data/enscribe-0.1.0/enscribe.c:79:18:  [3] (random) random:
  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.
#define FRand() (random()/(float)RAND_MAX)
data/enscribe-0.1.0/enscribe.c:80:24:  [3] (random) random:
  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.
#define FRand2() (2.0*(random()/(float)RAND_MAX)-1.0)
data/enscribe-0.1.0/enscribe.c:241:2:  [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 arg[256];
data/enscribe-0.1.0/enscribe.c:470:8:  [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).
					j=atoi(arg);
data/enscribe-0.1.0/enscribe.c:493:8:  [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).
					j=atoi(arg);
data/enscribe-0.1.0/enscribe.c:516:8:  [2] (integer) atol:
  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).
					j=atol(arg);
data/enscribe-0.1.0/enscribe.c:931:8:  [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).
		in = fopen(inputfilename, "r");
data/enscribe-0.1.0/enscribe.c:377:45:  [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).

data/enscribe-0.1.0/enscribe.c:385:6:  [1] (buffer) strncpy:

  pointers [MS-banned] (CWE-120).
