Alpine Linux: screen is setuid-root
Description
The Alpine package for GNU screen is installed setuid-root. This program is not designed to be secure and is almost certainly full of vulnerabilities, and the only use of suid-root installation is to support screen sessions shared between users, a rarely-used feature that most distributions disable. Some distros install screen setgid-utmp to update utmp, but since musl does not provide utmp, this is not necessary either. screen should simply be installed without any suid/sgid permissions.
