CVE-2021-29522: TensorFlow is an end-to-end open source platform for machine learning. The `tf.raw_ops.Conv3DBackprop*` operations fail
Summary
A bug in TensorFlow (an open source machine learning platform) allows attackers to cause a denial of service (making a system unavailable) by triggering a division by zero error in the `tf.raw_ops.Conv3DBackprop*` operations. The operations don't check if input tensors are empty before using them in calculations, which crashes the system if an attacker controls the input sizes.
Solution / Mitigation
The fix will be included in TensorFlow 2.5.0. It will also be applied to TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3, and TensorFlow 2.1.4.
