CVE-2022-23563: Tensorflow temporary file creation race condition via mktemp

Summary

TensorFlow uses `tempfile.mktemp` in multiple places to create temporary files, which is exploitable as a time-of-check to time-of-use (TOC/TOU) race: another process can create the file between the filename check in `mktemp` and the subsequent creation. In several instances TensorFlow was meant to create a temporary directory rather than a file, and this logic bug is hidden by the `mktemp` usage.

Mitigation

Patched in several commits by replacing `mktemp` with `mkstemp`/`mkdtemp` according to usage pattern. Users are advised to upgrade as soon as possible.
