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.
