NVD Description

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

telnetd in GNU inetutils through 2.7 allows privilege escalation that can be exploited by abusing systemd service credentials support added to the login(1) implementation of util-linux in release 2.40. This is related to client control over the CREDENTIALS_DIRECTORY environment variable, and requires an unprivileged local user to create a login.noauth file.
