Summary
Crash in `max_pool3d` when size argument is 0 or negative
Details

Impact

The Keras pooling layers can trigger a segfault if the size of the pool is 0 or if a dimension is negative: 

import tensorflow as tf

pool_size = [2, 2, 0]
layer = tf.keras.layers.MaxPooling3D(strides=1, pool_size=pool_size)
input_tensor = tf.random.uniform([3, 4, 10, 11, 12], dtype=tf.float32)
res = layer(input_tensor)

This is due to the TensorFlow's implementation of pooling operations where the values in the sliding window are not checked to be strictly positive.

Patches

We have patched the issue in GitHub commit 12b1ff82b3f26ff8de17e58703231d5a02ef1b8b (merging #51975).

The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range.
