NVD Description

Note: Versions mentioned in the description apply only to the upstream python-libs package and not the python-libs package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

The cleanup of tempfile.TemporaryDirectory is vulnerable to a race condition. An attacker who can modify the tree during cleanup can replace a directory with a symbolic link, causing files outside of the temporary directory to be deleted or have their permissions and file flags reset, with the privileges of the process performing the cleanup. Note that platforms where shutil.rmtree.avoids_symlink_attacks is false, remain affected, and file flags may still be reset outside of the tree on all platforms.
