QID 982457

QID 982457: Python (pip) Security Update for tensorflow (GHSA-4vrf-ff7v-hpgr)

The implementation of the `EmbeddingLookup` TFLite operator is [vulnerable to a division by zero error](https://github.com/tensorflow/tensorflow/blob/e4b29809543b250bc9b19678ec4776299dd569ba/tensorflow/lite/kernels/embedding_lookup.cc#L73-L74):

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

An attacker can craft a model such that the first dimension of the `value` input is 0.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.

CVSS V3 rated as High - 7.8 severity.

CVSS V2 rated as Medium - 4.6 severity.

Solution

We have patched the issue in GitHub commit [f61c57bd425878be108ec787f4d96390579fb83e](https://github.com/tensorflow/tensorflow/commit/f61c57bd425878be108ec787f4d96390579fb83e).

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.
