FINAL RESULTS:

data/garden-of-coloured-lights-1.0.9/src/main.c:155:2:  [5] (buffer) strncat:
  Easily used incorrectly (e.g., incorrectly computing the correct maximum
  size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
  or automatically resizing strings. Risk is high; the length parameter
  appears to be a constant, instead of computing the number of characters
  left.
	strncat(filename_buffer, "init.txt", sizeof(filename_buffer));
data/garden-of-coloured-lights-1.0.9/src/main.c:166:3:  [5] (buffer) strncat:
  Easily used incorrectly (e.g., incorrectly computing the correct maximum
  size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
  or automatically resizing strings. Risk is high; the length parameter
  appears to be a constant, instead of computing the number of characters
  left.
		strncat(right_path, "/.garden", sizeof(right_path) );
data/garden-of-coloured-lights-1.0.9/src/main.c:172:3:  [5] (buffer) strncat:
  Easily used incorrectly (e.g., incorrectly computing the correct maximum
  size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
  or automatically resizing strings. Risk is high; the length parameter
  appears to be a constant, instead of computing the number of characters
  left.
		strncat(right_path, "/init.txt", sizeof(right_path) );
data/garden-of-coloured-lights-1.0.9/src/input.c:97:3:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
		sprintf (sfile, "%s%02d", sfile, scrs);
data/garden-of-coloured-lights-1.0.9/src/main.c:156:6:  [4] (race) access:
  This usually indicates a security flaw. If an attacker can change anything
  along the path between the call to access() and the file's actual use
  (e.g., by moving files), the attacker can exploit the race condition
  (CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
  and try to open the file directly.
	if (access(filename_buffer, W_OK) == 0)

  (e.g., by moving files), the attacker can exploit the race condition
  (CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
  and try to open the file directly.

		if (access(right_path, R_OK) != 0 )
data/garden-of-coloured-lights-1.0.9/src/main.c:163:28:  [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.
		const char * unix_path = getenv("HOME");
data/garden-of-coloured-lights-1.0.9/src/main.c:164:29:  [3] (buffer) getenv:

data/garden-of-coloured-lights-1.0.9/src/main.c:213:2:  [3] (random) srand:
  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.

	char istr[64];
data/garden-of-coloured-lights-1.0.9/src/input.c:96:3:  [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 (sfile, "screenshot_");
data/garden-of-coloured-lights-1.0.9/src/input.c:99:3:  [2] (buffer) strcat:
