NVD Description

Note: Versions mentioned in the description apply only to the upstream screen package and not the screen package as distributed by Alpine. See How to fix? for Alpine:3.19 relevant fixed versions and status.

A minor information leak when running Screen with setuid-root privileges allows unprivileged users to deduce information about a path that would otherwise not be available.

Affected are older Screen versions, as well as version 5.0.0.
