FINAL RESULTS:

data/cdde-0.3.1/src/string.c:64:2:  [4] (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).
	strcpy(dst, left);
data/cdde-0.3.1/src/util.c:79:12:  [4] (shell) system:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.
		status = system(command);
data/cdde-0.3.1/src/cdde.c:417:30:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
		filename = (char *) strdup(getenv("HOME"));
data/cdde-0.3.1/src/util.c:116:14:  [3] (buffer) getopt_long:
  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_long(argc, argv, "c:Vvhrb", long_options, &longindex)) != -1)
data/cdde-0.3.1/src/cdde.c:196:7:  [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(device, O_RDONLY);
data/cdde-0.3.1/src/cdde.c:281:7:  [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(d->filename, O_RDONLY | O_NONBLOCK);
data/cdde-0.3.1/src/cdde.c:419:23:  [2] (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). Risk is low because the
  source is a constant string.
		filename = (char *) strcat(filename, "/.cdde.xml");
data/cdde-0.3.1/src/string.c:57:3:  [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(dst, left, cnt);
data/cdde-0.3.1/src/string.c:59:3:  [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(dst, newstr, newlen);
data/cdde-0.3.1/src/cdde.c:167:2:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	read(fd, var, width);
data/cdde-0.3.1/src/cdde.c:228:3:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
		read(fd, &len_di, 1);
data/cdde-0.3.1/src/cdde.c:233:3:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
		read(fd, &parent, 2);
data/cdde-0.3.1/src/cdde.c:239:3:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
		read(fd, dirname, len_di);
data/cdde-0.3.1/src/cdde.c:418:34:  [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).
		filename = realloc(filename, ((strlen(filename)+1) + strlen("/.cdde.xml")) * sizeof(char));
data/cdde-0.3.1/src/cdde.c:418:56:  [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).
		filename = realloc(filename, ((strlen(filename)+1) + strlen("/.cdde.xml")) * sizeof(char));
data/cdde-0.3.1/src/cdde.c:475:3:  [1] (obsolete) usleep:
  This C routine is considered obsolete (as opposed to the shell command by
  the same name). The interaction of this function with SIGALRM and other
  timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is
  unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead.
		usleep(delay);
data/cdde-0.3.1/src/string.c:45:8:  [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).
	len = strlen(str);
data/cdde-0.3.1/src/string.c:46:11:  [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).
	oldlen = strlen(oldstr);
data/cdde-0.3.1/src/string.c:50:11:  [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).
	newlen = strlen(newstr);
data/cdde-0.3.1/src/string.c:65:21:  [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).
	buf = realloc(buf, strlen(buf) + 1);
data/cdde-0.3.1/src/util.c:67:19:  [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).
	if (!command || !strlen(command)) return;
data/cdde-0.3.1/src/util.c:181:2:  [1] (access) umask:
  Ensure that umask is given most restrictive possible setting (e.g., 066 or
  077) (CWE-732).
	umask(0);
