CVE-2022-23588: `CHECK`-fails due to attempting to build a reference tensor
(updated )
A malicious user can cause a denial of service by altering a SavedModel such that Grappler optimizer would attempt to build a tensor using a reference dtype. This would result in a crash due to a CHECK-fail in the Tensor constructor as reference types are not allowed.
