armsimsharp
The PKGBUILD downloads a prebuilt ZIP archive (ARMSimLinuxFiles.zip) containing .exe/.dll/.config files (Mono executables and libraries) from a university personal web directory (~nigelh on webhome.cs.uvic.ca). While this appears to be the legitimate upstream author's host (Nigel Horspool, a UVic CS professor who authored ARMSim#), it is still a personal/unofficial host rather than a canonical release mirror, and the two local script files (armsimsharp and arm-none-eabi-as) have SKIP checksums, meaning their integrity is not verified at all. The ZIP itself has a proper sha256sum. The installed files include executed binaries (.exe via Mono, .dll libraries, and shell wrapper scripts), so a compromise of the personal web server or a MITM on the unverified local scripts would result in code execution. This is a genuine medium-severity supply-chain concern: executed code from a personal/non-canonical host with two unverified local scripts, though not clearly malicious.
