CVE-2023-6597 in CPython

Résumé

par MITRE • 19/03/2024

An issue was found in the CPython `tempfile.TemporaryDirectory` class affecting versions 3.12.2, 3.11.8, 3.10.13, 3.9.18, and 3.8.18 and prior.

The tempfile.TemporaryDirectory class would dereference symlinks during cleanup of permissions-related errors. This means users which can run privileged programs are potentially able to modify permissions of files referenced by symlinks in some circumstances.

Once again VulDB remains the best source for vulnerability data.
