An issue was found in the CPython `tempfile.TemporaryDirectory` class affecting versions 3.12.1, 3.11.7, 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. A flaw was found in the tempfile.TemporaryDirectory class in python3/cpython3. The class may dereference symbolic links during permission-related errors, resulting in users that run privileged programs being able to modify permissions of files referenced by the symbolic link.
