QID 981475: Python (pip) Security Update for tensorflow-gpu (GHSA-8fxw-76px-3rxv)

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.

If a user passes a list of strings to `dlpack.to_dlpack` there is a memory leak following an expected validation failure:
https://github.com/tensorflow/tensorflow/blob/0e68f4d3295eb0281a517c3662f6698992b7b2cf/tensorflow/c/eager/dlpack.cc#L100-L104

The allocated memory is from
https://github.com/tensorflow/tensorflow/blob/0e68f4d3295eb0281a517c3662f6698992b7b2cf/tensorflow/c/eager/dlpack.cc#L256

The issue occurs because the `status` argument during validation failures is not properly checked:
https://github.com/tensorflow/tensorflow/blob/0e68f4d3295eb0281a517c3662f6698992b7b2cf/tensorflow/c/eager/dlpack.cc#L265-L267

Since each of the above methods can return an error status, the `status` value must be checked before continuing.

CVSS V3 rated as Medium - 4.3 severity.

CVSS V2 rated as Medium - 4 severity.

Solution

We have patched the issue in 22e07fb204386768e5bcbea563641ea11f96ceb8 and will release a patch release for all affected versions.
