NVD Description
Note: Versions mentioned in the description apply only to the upstream python3-tkinter package and not the python3-tkinter package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
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.
