Description

wall in util-linux through 2.40, often installed with setgid tty permissions, allows escape sequences to be sent to other users' terminals through argv.

• util-linux: from 2.24 before 2.39.4 — fixed in 2.39.4

How to fix

Upgrade to a fixed version: util-linux 2.39.4. Check the vendor advisory for mitigations.
