## Overview

### Impact
The implementation of [`tf.raw_ops.TensorSummaryV2`](https://github.com/tensorflow/tensorflow/blob/f3b9bf4c3c0597563b289c0512e98d4ce81f886e/tensorflow/core/kernels/summary_tensor_op.cc#L33-L58) does not fully validate the input arguments. This results in a `CHECK`-failure which can be used to trigger a denial of service attack:

```python
import numpy as np
import tensorflow as tf

tf.raw_ops.TensorSummaryV2(
  tag=np.array('test'),
  tensor=np.array(3),
  serialized_summary_metadata=tf.io.encode_base64(np.empty((0))))
```

The code assumes `axis` is a scalar but there is no validation for this.

```cc
    const Tensor& serialized_summary_metadata_tensor = c->input(2);
    // ...
    ParseFromTString(serialized_summary_metadata_tensor.scalar<tstring>()(),
                     v->mutable_metadata());
``` 

### Patches
We have patched the issue in GitHub commit [290bb05c80c327ed74fae1d089f1001b1e2a4ef7](https://github.com/tensorflow/tensorflow/commit/290bb05c80c327ed74fae1d089f1001b1e2a4ef7).
    
The fix will be included in TensorFlow 2.9.0. We will also cherrypick this commit on TensorFlow 2.8.1, TensorFlow 2.7.2, and TensorFlow 2.6.4, as these are also affected and still in supported range.
