FINAL RESULTS:

data/python-systemd-234/systemd/util.c:68:13:  [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("/proc/net/if_inet6", F_OK) != 0)
data/python-systemd-234/systemd/util.c:92:21:  [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).
                if (strlen(s) > IF_NAMESIZE-1)
