MEDIUM

Why flagged The package sets the setuid bit on the installed binary 'maildrop' using chmod u+s, which is a privileged operation that could pose a security risk if the binary is compromised.

Triggered rules

MEDIUM Privileged / out-of-pacman install (sudoers, setuid, or self-update) privileged_install

The package grants elevated privileges or installs an update path outside pacman: a /etc/sudoers.d rule (often passwordless), a setuid/setgid binary, or a self-update script/service that can fetch and run future code with no checksum verification. The initial install may be verified, but the ongoing privilege + update surface is a real supply-chain / privilege-escalation risk.

PKGBUILD:37 chmod u+s "${pkgdir}/usr/bin/maildrop"
