fdtools is a set of utilities for working with file descriptors. With these tools, you can examine and manipulate file descriptor properties from shell scripts, where without them you might have resorted to a different language. These tools can rewind file descriptors, switch them between blocking and nonblocking mode, and examine their inode information. On some systems (currently only Linux, as far as I know) they can also allocate, lock, and switch virtual consoles.
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.
