NVD Description

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

filelock is a platform-independent file lock for Python. From 3.20.4 until 4.0.9, ReadWriteLock and AsyncReadWriteLock versions from 3.20.4 resolve the lock path and pass it to SQLite without rejecting a final symbolic link, allowing another local user who can create names in the lock directory to redirect database creation and locking or split mutual exclusion between targets. This issue is fixed in version 4.0.9.
