FINAL RESULTS:

data/dh-exec-0.23.2/src/dh-exec.c:324:15:  [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.

  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.

  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
