FINAL RESULTS:

data/suil-0.10.8/src/suil_internal.h:35:31:  [4] (format) fprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
#define SUIL_ERRORF(fmt, ...) fprintf(stderr, "suil error: " fmt, __VA_ARGS__)
data/suil-0.10.8/src/dylib.h:33:9:  [3] (misc) LoadLibrary:
  Ensure that the full path to the library is specified, or current directory
  may be used (CWE-829, CWE-20). Use registry entry or GetWindowsDirectory to
  find library path, if you aren't already.
	return LoadLibrary(filename);
data/suil-0.10.8/src/suil_internal.h:107:31:  [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* const env_dir  = getenv("SUIL_MODULE_DIR");
data/suil-0.10.8/src/suil_internal.h:109:31:  [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).
	const size_t      path_len = strlen(mod_dir)
data/suil-0.10.8/src/suil_internal.h:110:5:  [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).
		+ strlen(SUIL_DIR_SEP SUIL_MODULE_PREFIX SUIL_MODULE_EXT)
data/suil-0.10.8/src/suil_internal.h:111:5:  [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).
