CVE-2022-29192

Missing validation crashes `QuantizeAndDequantizeV4Grad` in TensorFlow

5.5 MediumFix available

TensorFlow is an open source platform for machine learning. Prior to versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4, the implementation of tf.raw_ops.QuantizeAndDequantizeV4Grad does not fully validate the input arguments. This results in a CHECK-failure which can be used to trigger a denial of service attack. Versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4 contain a patch for this issue.

Missing validation crashes `QuantizeAndDequantizeV4Grad`

Impact

The implementation of tf.raw_ops.QuantizeAndDequantizeV4Grad does not fully validate the input arguments. This results in a CHECK-failure which can be used to trigger a denial of service attack:

import tensorflow as tf

tf.raw_ops.QuantizeAndDequantizeV4Grad(
  gradients=tf.constant(1, shape=[2,2], dtype=tf.float64),
  input=tf.constant(1, shape=[2,2], dtype=tf.float64),
  input_min=tf.constant([], shape=[0], dtype=tf.float64),
  input_max=tf.constant(-10, shape=[], dtype=tf.float64),
  axis=-1)

The code assumes input_min and input_max are scalars but there is no validation for this.

Patches

We have patched the issue in GitHub commit 098e7762d909bac47ce1dbabe6dfd06294cb9d58.

The fix will be included in TensorFlow 2.9.0. We will also cherrypick this commit on TensorFlow 2.8.1, TensorFlow 2.7.2, and TensorFlow 2.6.4, as these are also affected and still in supported range.
