CVE-2022-23588: Tensorflow denial of service through altered SavedModel reference dtype

Summary

CVE-2022-23588 affects TensorFlow, an open source machine learning framework. A malicious user can alter a `SavedModel` so that the Grappler optimizer tries to build a tensor using a reference `dtype`, which triggers a `CHECK`-fail in the `Tensor` constructor and crashes the process, causing a denial of service.

Mitigation

The fix will be included in TensorFlow 2.8.0. The commit will also be cherrypicked to TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3.
