Heap OOB read in `tf.raw_ops.SparseCountSparseOutput`

Impact

The shape inference functions for SparseCountSparseOutput can trigger a read outside of bounds of heap allocated array:

import tensorflow as tf

@tf.function
def func():
  return tf.raw_ops.SparseCountSparseOutput(
    indices=[1],
    values=[[1]],
    dense_shape=[10],
    weights=[],
    binary_output= True)

func()

The function fails to check that the first input (i.e., indices) has rank 2:

  auto rank = c->Dim(c->input(0), 1);

Patches

We have patched the issue in GitHub commit 701cfaca222a82afbeeb17496bd718baa65a67d2.

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.
