FINAL RESULTS:

data/haskell-system-fileio-0.3.16.4/lib/hssystemfileio-unix.c:122:9:  [5] (race) chmod:
  This accepts filename arguments; if an attacker can move those files, a
  race condition results. (CWE-362). Use fchmod( ) instead.
	return chmod(new_path, st.st_mode);
data/haskell-system-fileio-0.3.16.4/lib/hssystemfileio-unix.c:129:9:  [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).
	return open(path, mode);
