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. We have patched the issue in several commits, replacing `mktemp` with the safer `mkstemp`/`mkdtemp` functions, according to the usage pattern. Users are advised to upgrade as soon as possible.","affected":[{"package":{"name":"tensorflow","ecosystem":"Bitnami","purl":"pkg:bitnami/tensorflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.5.3"},{"introduced":"2.6.0"},{"fixed":"2.6.3"},{"introduced":"2.7.0"},{"fixed":"2.7.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/tensorflow/BIT-tensorflow-2022-23563.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"}]}],"references":[{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-wc4g-r73w-x8mm"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23563"}],"database_specific":{"cpes":["cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*","cpe:2.3:a:google:tensorflow:2.7.0:*:*:*:*:*:*:*"],"severity":"High"}}
