CVE-2022-1348

Log rotation denial via lockable state file

Published May 25, 2022 · Updated Jun 9, 2025

Denial of service in Logrotate Project logrotate 3.17.0 through 3.19.0 allows local users to stop log rotation through the state file. The lockState function creates a missing state file with mode 0644, allowing any local account to open it and hold the exclusive lock before logrotate runs. A default umask of 0022 leaves the file world-readable; an unprivileged local account can retain the lock so scheduled rotations fail.
