Why flagged

The source is a prebuilt binary downloaded from the official upstream domain (icesl.loria.fr), which is the legitimate vendor site for IceSL from INRIA/Loria. This is not a personal or unofficial host. However, the download URL is a PHP script (download.php) that dynamically serves a binary, and the sha512sum provided has only 127 hex characters instead of the required 128 (it appears truncated/malformed), which means integrity verification is effectively broken. A malformed checksum means makepkg will likely fail the check or skip it, leaving the binary unverified. The binary is installed and symlinked into /usr/bin for execution. The combination of a dynamically-served prebuilt binary and a broken/truncated checksum constitutes a real supply-chain concern: if the upstream server is compromised or serves a different binary, there is no integrity check to catch it. This warrants medium severity due to the executed binary with non-functional checksum, even though the host itself is the legitimate upstream.

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, …).
