Why flagged

The package downloads source from a legitimate project host (caida.org) which is not on standard whitelists but is authentic, so the non-standard host flag is low risk; however, the package sets a setuid bit on scamper with chmod u+s, which is a privileged operation that can elevate privileges if exploited, raising a real but moderate security concern.

Triggered rules

Medium source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).

PKGBUILD:10 source=("https://www.caida.org/catalog/software/scamper/code/$pkgname-cvs-$pkgver.tar.gz")

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:27 chmod u+s $pkgdir/usr/bin/scamper
