PyPI: tensorflow-macos
CVE-2022-23563
Safety vulnerability ID: SFTY-20220204-70244
Safety legacy ID: pyup.io-58391
Tensorflow versions 2.5.3, 2.6.3, 2.7.1 and 2.8.0 include a fix for CVE-2022-23563: In multiple places, TensorFlow uses 'tempfile.mktemp' to create temporary files. While this is acceptable in testing, in utilities and libraries it is dangerous as a different process can create the file between the check for the filename in 'mktemp' and the actual creation of the file by a subsequent operation (a TOC/TOU type of weakness). In several instances, TensorFlow was supposed to actually create a temporary directory instead of a file. This logic bug is hidden away by the 'mktemp' function usage. It was replaced 'mktemp' with the safer 'mkstemp'/'mkdtemp' functions, according to the usage pattern. https://github.com/tensorflow/tensorflow/security/advisories/GHSA-wc4g-r73w-x8mm
