MEDIUM

Why flagged The PKGBUILD downloads a prebuilt proprietary binary RPM (containing executables nero, nerocmd, neroexpress) from nero-mirror.com, which is not the official nero.com domain. The official URL is listed as nerolinux.nero.com but the source is pulled from a third-party mirror domain. This is a genuine supply-chain concern: if nero-mirror.com is not officially operated by Nero AG, the binary could be tampered with. The MD5 checksum provides weak integrity assurance (MD5 is cryptographically broken). The package installs and executes these binaries directly. This fits the medium severity definition: executed binaries from an unofficial/personal host.
