MEDIUM

Why flagged This PKGBUILD downloads a prebuilt binary shared library (libCCGraphiteP11.so) from download.cryptotech.com.pl with sha256sums_x86_64='SKIP', meaning no integrity verification is performed on the executed binary. The library is a PKCS#11 module that will be loaded into security-sensitive processes (e.g., browsers, SSH agents, smart card middleware). Additionally, the DLAGENTS override uses --insecure to disable TLS certificate verification, removing the only remaining transport-layer protection. While cryptotech.com.pl appears to be the legitimate vendor's own download server (matching the package URL), the combination of: (1) a prebuilt binary installed as a system library, (2) no checksum verification, and (3) TLS verification explicitly disabled constitutes a genuine supply-chain risk. If the download server is compromised or the DNS is hijacked, an arbitrary .so would be installed with no integrity check. This is a real medium-severity concern, not a false positive.
