When tf.random.gamma receives large input shape and rates, it gives a CHECK fail that can trigger a denial of service attack.

We have patched the issue in GitHub commit 552bfced6ce4809db5f3ca305f60ff80dd40c5a3.
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.
Please consult our security guide for more information regarding the security model and how to contact us with issues and questions.
