FINAL RESULTS:

data/python-persistent-4.6.4/persistent/cPersistence.c:1496:9:  [4] (format) snprintf:
  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
        snprintf(buf, sizeof(buf) - 1, "%" PRIx64, oid_value);
data/python-persistent-4.6.4/persistent/cPersistence.c:59:15:  [3] (random) setstate:
  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.
  INIT_STRING(setstate);

  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.

data/python-persistent-4.6.4/persistent/cPersistence.h:119:93:  [3] (random) setstate:

  acquiring random values.

  Statically-sized arrays can be improperly restricted, leading to potential
