MEDIUM

Why flagged This PKGBUILD downloads a prebuilt binary package (a compiled X.org/XLibre video driver) from x11libre.net, which is a self-hosted distribution site rather than a well-known, widely-trusted package mirror or the upstream GitHub releases page. The binary is a kernel/X server interface driver (.so) that will be installed into the system and executed with elevated privileges during X server operation. While XLibre is a real fork of X.Org and x11libre.net appears to be its official distribution site, the host is not independently verifiable as a major trusted infrastructure (like GitHub releases, PyPI, crates.io, etc.), and there is only a single SHA256 checksum for integrity — no GPG signature verification. The package also uses noextract and manually tars into pkgdir, bypassing normal pacman package validation. If x11libre.net were compromised or the maintainer's control over it were lost, a malicious binary could be silently substituted. This is a genuine supply-chain concern for an executed binary from a non-mainstream host, consistent with a MEDIUM rating.

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, …).
