How to fix?

Upgrade Alpine:3.13 openrc to version 0.42.1-r20 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openrc package and not the openrc package as distributed by Alpine. See How to fix? for Alpine:3.13 relevant fixed versions and status.

checkpath in OpenRC through 0.42.1 might allow local users to take ownership of arbitrary files because a non-terminal path component can be a symlink.
