FINAL RESULTS:

data/dhis-tools-dns-5.0/genkeys.c:52:3:  [4] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused).
		strcat(buff,temp);
data/dhis-tools-dns-5.0/genkeys.c:46:22:  [3] (random) srandom:
  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.
	if(!seed) { seed++; srandom(time(NULL)); }
data/dhis-tools-dns-5.0/genkeys.c:51:22:  [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.
		sprintf(temp,"%lu",random());
data/dhis-tools-dns-5.0/genpass.c:39:2:  [3] (random) srandom:
  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.
	srandom(time(NULL));
data/dhis-tools-dns-5.0/genpass.c:42:6:  [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.
			i=random() % ('z'+1); 
data/dhis-tools-dns-5.0/genid.c:45:18:  [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.
	static unsigned char b2[1024],*pb2;
data/dhis-tools-dns-5.0/genid.c:76:11:  [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.
	unsigned char str[1024];
data/dhis-tools-dns-5.0/genid.c:79:5:  [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).
	fp=fopen("/etc/dhis-server/dhis.db","r");
data/dhis-tools-dns-5.0/genid.c:84:7:  [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).
	  if(atoi(line_entry(1,str)) > id) id=atoi(line_entry(1,str));
data/dhis-tools-dns-5.0/genid.c:84:40:  [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).
	  if(atoi(line_entry(1,str)) > id) id=atoi(line_entry(1,str));
data/dhis-tools-dns-5.0/genkeys.c:43:2:  [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 buff[1024],temp[128];
data/dhis-tools-dns-5.0/genkeys.c:51:3:  [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(temp,"%lu",random());
data/dhis-tools-dns-5.0/genkeys.c:98:11:  [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.
	unsigned char buff[1024];
data/dhis-tools-dns-5.0/genkeys.c:99:11:  [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.
	unsigned char chunk[128];
data/dhis-tools-dns-5.0/genkeys.c:107:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
		memcpy(chunk,cp,50);
data/dhis-tools-dns-5.0/genpass.c:52:11:  [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.
	unsigned char pass[16];
data/dhis-tools-dns-5.0/genkeys.c:54:10:  [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).
	} while(strlen(buff) < n);
