MEDIUM

Why flagged The PKGBUILD downloads prebuilt binary tarballs (containing executables and shared libraries: opt/bin/mediasrv, opt/lib/*.so) directly from sundtek.de over plain HTTP with SKIP checksums, meaning there is no integrity verification whatsoever. These binaries are then installed into /opt/bin and /opt/lib and will be executed at runtime. sundtek.de is the official vendor website for Sundtek hardware, so the host itself is not suspicious, but: (1) plain HTTP allows MITM substitution of the binaries, (2) SKIP checksums mean any tampered tarball would be accepted silently, and (3) the version is extracted by running 'strings' on the downloaded binary mediasrv, which is a mild concern but not itself dangerous. This is a genuine supply-chain concern — unverified prebuilt binaries from a vendor host over unencrypted HTTP — qualifying as medium risk. It is not high because sundtek.de is the legitimate vendor and there is no evidence of malicious intent, but the lack of any checksum on executed code is a real packaging deficiency.
