Summary
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.
