Short explanation
The SoftReadWriteLock component in filelock allows local users with rename access to replace records with named pipes to stall the lock or write through hard links [S0].
It enables a local attacker to disrupt file locking mechanisms and compromise data integrity by writing through linked target files [S0].
What should be done?
- Follow vendor advisories [S0]
- Apply updates [S0]

Show the technical text from the sources
filelock is a platform-independent file lock for Python. From 4.0.0 until 4.2.1, SoftReadWriteLock refreshes holder records by name, allowing another local user with rename access to the lock directory to replace a record with a named pipe and stall the lock, or under a permissive hard-link policy to link a reachable target file and cause the lock user to write through it. This issue is fixed in version 4.2.1.
