MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary installer from sldev.free.fr, which is the official (though personal/hobbyist-style) distribution host for the Cool VL Viewer project — a long-standing third-party Second Life viewer maintained by Henri Beauchamp. The domain is the project's canonical upstream, not a random personal host. However, the binary is executed directly during build() (chmod +x + run as installer), and only a SHA1 checksum is used for integrity verification. SHA1 is cryptographically weak and insufficient for verifying an executed binary. The combination of: (1) a prebuilt binary installer being executed, (2) hosted on a free-tier personal domain (free.fr) with no TLS in the source URL (http://), and (3) only SHA1 integrity checking, constitutes a genuine medium-severity supply-chain risk. If the host were compromised or the binary silently replaced, the weak checksum provides little protection. This is not clearly malicious, but it is a real concern for an executed binary package.
