On Windows, the filelock library's ReadWriteLock and AsyncReadWriteLock use SQLite side files for locking. A local user who can create files but not delete others' files in the lock directory can place a specially crafted side file (e.g., -wal or -journal) beside the database. This causes the lock user to encounter disk I/O errors or unexpected file deletions during lock acquisition, resulting in partial denial of service. The issue affects filelock versions 3.20.4 through 4.2.0 on Windows. A fix is available in version 3.25.2_5.
