MEDIUM

Why flagged The PKGBUILD downloads a ZIP archive from jestershelter.xyz, a personal/unofficial host with no affiliation to Microsoft or any recognized software mirror. The archive contains Windows PE binaries (mspaint.exe and related files) that are executed via Wine. While a sha256sum is provided (offering some integrity protection), the hash only guarantees the file hasn't changed since the PKGBUILD was written — it does not establish that the binary is trustworthy or unmodified from the original XP mspaint. The original mspaint.exe from Windows XP is proprietary Microsoft software; distributing it via a personal host raises both supply-chain concerns (the host owner controls the binary) and potential licensing issues (redistributing proprietary Microsoft binaries without authorization). The sha256 check mitigates substitution attacks but not the initial trust problem. This is a genuine medium-severity supply-chain concern: an executed binary from an unofficial personal host.
