Summary
TensorFlow vulnerable to `CHECK` fail in `EmptyTensorList`
Details

Impact

If EmptyTensorList receives an input element_shape with more than one dimension, it gives a CHECK fail that can be used to trigger a denial of service attack.

import tensorflow as tf

tf.raw_ops.EmptyTensorList(element_shape=tf.ones(dtype=tf.int32, shape=[1, 0]), max_num_elements=tf.constant(1),element_dtype=tf.int32)

Patches

We have patched the issue in GitHub commit c8ba76d48567aed347508e0552a257641931024d.

The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range.
