MEDIUM

Why flagged problemkaputt.de is Martin Korth's well-known personal site, the canonical upstream for all no$xxx emulators/debuggers (no$gba, no$sns, no$2k6, etc.). This is effectively the official vendor host. However, the package downloads a prebuilt Windows PE binary (run under Wine) with only an md5sum for integrity — MD5 is weak but provides some verification. The wrapper script, desktop file, and icon are sourced locally (SKIP checksums, which is sloppy but not dangerous for non-executed data files). The real concern is that a prebuilt closed-source binary from a personal host is executed via Wine with no stronger hash (SHA256/SHA512) and no signature verification. This is a genuine medium-severity supply-chain concern: if problemkaputt.de were compromised, users would silently receive a malicious binary. The host is legitimate/well-known, which lowers the probability of compromise, but the pattern (prebuilt binary, weak hash, personal host) still warrants medium rather than clean.

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, …).
