CVE-ID: CVE-2022-1348

CWE-ID: CWE-276 - Incorrect Default Permissions

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to the way logrotate uses the state file. 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.

Mitigation

Update the affected package logrotate to the latest version.
