A vulnerability was found in logrotate in how the state file is created.
The state file is used to prevent parallel executions of multiple instances
of logrotate by acquiring and releasing a file lock. When the state file
does not exist, it is created with world-readable permission, allowing an
unprivileged user to lock the state file, stopping any rotation. This flaw
affects logrotate versions before 3.20.0.
Notes
| Author | Note |
|---|---|
| alexmurray | Only affects logrotate >= 3.17.0 |
| mdeslaur | Ubuntu packages build with: --with-state-file-path=/var/lib/logrotate/status but the /var/lib/logrotate directory itself is 755, so a user can get a lock on the file. See follow-up pull request with additional fix |
