TFSA-2022-030: CHECK-fail when decoding resource handles from proto

CVE Number

CVE-2022-23564

Impact

When decoding a resource handle tensor from protobuf, a TensorFlow process can encounter cases where a CHECK assertion is invalidated based on user controlled arguments. This allows attackers to cause denial of services in TensorFlow processes.

Patches

We have patched the issue in GitHub commit 14fea662350e7c26eb5fe1be2ac31704e5682ee6.

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.
