Overflow and uncaught divide by zero in Tensorflow
Impact
The implementation of UnravelIndex is vulnerable to a division by zero caused by an integer overflow bug:
Patches
We have patched the issue in GitHub commit 58b34c6c8250983948b5a781b426f6aa01fd47af.
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.
