SCA: security update for tensorflow, tensorflow-cpu, tensorflow-gpu (GHSA-gh6x-4whr-2qv4)

high Tenable Cloud Security Plugin ID 415136

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - TensorFlow is an end-to-end open source platform for machine learning. When restoring tensors via raw
 APIs, if the tensor name is not provided, TensorFlow can be tricked into dereferencing a null pointer.
 Alternatively, attackers can read memory outside the bounds of heap allocated data by providing some
 tensor names but not enough for a successful restoration. The [implementation](https://github.com/tensorfl
 ow/tensorflow/blob/47a06f40411a69c99f381495f490536972152ac0/tensorflow/core/kernels/save_restore_tensor.cc
 #L158-L159) retrieves the tensor list corresponding to the `tensor_name` user controlled input and
 immediately retrieves the tensor at the restoration index (controlled via `preferred_shard` argument).
 This occurs without validating that the provided list has enough values. If the list is empty this results
 in dereferencing a null pointer (undefined behavior). If, however, the list has some elements, if the
 restoration index is outside the bounds this results in heap OOB read. We have patched the issue in GitHub
 commit 9e82dce6e6bd1f36a57e08fa85af213e2b2f2622. The fix will be included in TensorFlow 2.6.0. We will
 also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also
 affected and still in supported range. (CVE-2021-37639)
