FINAL RESULTS:

data/rdate-1.10/src/rdate.c:112:14:  [3] (buffer) getopt:
  Some older implementations do not protect against internal buffer overflows
  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
	while ((c = getopt(argc, argv, "46psancvuo:t:b:")) != -1)
data/rdate-1.10/src/ntp.c:445:2:  [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(&data->recvck,packet+NTP_ORIGINATE,8);
data/rdate-1.10/src/ntpleaps.c:113:2:  [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(&res, ptr, 4);
data/rdate-1.10/src/ntpleaps.c:128:7:  [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).
	fd = open("/usr/share/zoneinfo/right/UTC", O_RDONLY | O_NDELAY);
data/rdate-1.10/src/rdate.c:151:11:  [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).
			port = atoi(optarg);
data/rdate-1.10/src/rdate.c:155:15:  [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).
			maxdelay = atoi(optarg);
data/rdate-1.10/src/rdate.c:159:23:  [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).
			conditionalslide = atoi(optarg);
data/rdate-1.10/src/rdate.c:216:3:  [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[80];
data/rdate-1.10/src/rdate.c:227:5:  [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 slidemsg[32];
data/rdate-1.10/src/rdate.c:230:9:  [2] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused). Risk is low because the source is a constant string.
		      strcpy(slidemsg," (adjtime)");
data/rdate-1.10/src/rdate.c:232:9:  [2] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused). Risk is low because the source is a constant string.
		      strcpy(slidemsg," (instant change)");
data/rdate-1.10/src/ntp.c:361:11:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	length = read(fd, receive, NTP_PACKET_MAX);
data/rdate-1.10/src/ntpleaps.c:133:6:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	if (read(fd, buf, 4)) {};
data/rdate-1.10/src/ntpleaps.c:147:6:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	if (read(fd, buf, 28)) {};
data/rdate-1.10/src/ntpleaps.c:162:6:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	if (read(fd, buf, 12)) {};
data/rdate-1.10/src/ntpleaps.c:171:7:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
		if (read(fd, buf, 8) != 8) {
data/rdate-1.10/src/rdate.c:235:7:  [1] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused). Risk is low because the source is a constant character.
		    strcpy(slidemsg,"");
data/rdate-1.10/src/rfc868time.c:113:6:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	if (read(s, &tim, sizeof(tim)) != sizeof(tim))
