Ubuntu 21.10 / 22.04 LTS : logrotate vulnerability (USN-5447-1)

medium Nessus Plugin ID 161615

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 21.10 / 22.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-5447-1 advisory.

- 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.
(CVE-2022-1348)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected logrotate package.
