hie-bios is the way to specify how haskell-language-server and ghcide set up a GHC API session. Given a Haskell project that is managed by Stack, Cabal, or other package tools, haskell-language-server needs to know the full set of flags to pass to GHC in order to build the project. These flags might contain some compilation options like -O2, but a lot of the time they are package dependencies such as -package-id directory-22.214.171.124, which also need to be built beforehand. hie-bios satisfies both these needs.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
