Fedora 32: 2021-5e9894a0c5 Critical: DoS in Screen Utility

The screen utility allows you to have multiple logins on just one

terminal. Screen is useful for users who telnet into a machine or are

connected via a dumb terminal, but want to use more than just one

login.

Install the screen package if you need a screen manager that can

support multiple logins on one terminal.
