Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - filelock is a platform-independent file lock for Python. From 3.20.4 until 4.2.1, ReadWriteLock let SQLite
 reopen the database and side files by name; on POSIX systems an attacker with rename access in a non-
