Advisoriesby Ibis`CHECK`-failures during Grappler's `IsSimplifiableReshape` in Tensorflow
Impact
The Grappler optimizer in TensorFlow can be used to cause a denial of service by altering a SavedModel such that [IsSimplifiableReshape](https://github.com/tensorflow/tensorflow/blob/a1320ec1eac186da1d03f033109191f715b2b130/tensorflow/core/grappler/optimizers/constant_folding.cc#L1687-L1742) would trigger CHECK failures.
Patches
We have patched the issue in GitHub commits [ebc1a2ffe5a7573d905e99bd0ee3568ee07c12c1](https://github.com/tensorflow/tensorflow/commit/ebc1a2ffe5a7573d905e99bd0ee3568ee07c12c1), [1fb27733f943295d874417630edd3b38b34ce082](https://github.com/tensorflow/tensorflow/commit/1fb27733f943295d874417630edd3b38b34ce082), and [240655511cd3e701155f944a972db71b6c0b1bb6](https://github.com/tensorflow/tensorflow/commit/240655511cd3e701155f944a972db71b6c0b1bb6).
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.
