QID 982449: Python (pip) Security Update for tensorflow (GHSA-8rm6-75mf-7r7r)

Security update has been released for tensorflow 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.

The TFLite implementation of hashtable lookup is [vulnerable to a division by zero error](https://github.com/tensorflow/tensorflow/blob/1a8e885b864c818198a5b2c0cbbeca5a1e833bc8/tensorflow/lite/kernels/hashtable_lookup.cc#L114-L115):

```cc
const int num_rows = SizeOfDimension(value, 0);
const int row_bytes = value->bytes / num_rows;
```

An attacker can craft a model such that `values`'s first dimension would be 0.

CVSS V3 rated as Medium - 5.5 severity.

CVSS V2 rated as Low - 2.1 severity.

Solution

We have patched the issue in GitHub commit [5117e0851348065ed59c991562c0ec80d9193db2](https://github.com/tensorflow/tensorflow/commit/5117e0851348065ed59c991562c0ec80d9193db2).

The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.
