The `tf.raw_ops.ParameterizedTruncatedNormal` operation does not validate its input arguments before accessing the first element of `shape`. An attacker who supplies an empty `shape` triggers undefined behavior by binding to a null pointer.","solution":"The fix will be included in TensorFlow 2.5.0.
