[arch-general] Is screen safe when it has setsuid?

[Iru Cai]

Hello,

I saw that the permission of screen is -rwsr-xr-x, which means when screen
is run, it's run as root at the beginning. I don't know if it can be a
security issue.

I also checked the screen program in Debian. It uses setguid as a non-root
group.
-rwxr-sr-x 1 root utmp ... /usr/bin/screen
