Related CVEs: * CVE-2022-1348: logrotate: potential DoS from unprivileged users via the state file
Ubuntu Security Notice 5447-1 - It was discovered that logrotate incorrectly handled the state file. A local attacker could possibly use this issue to keep a lock on the state file and cause logrotate to stop working, leading to a denial of service.
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.
