pax-utils is a small set of utilities for performing Q/A (mostly security) checks on systems (most notably, `scanelf`). It is focused on the ELF format, but does include a Mach-O helper too for OS X systems. While heavily integrated into Gentoo's build system, it can be used on any distro as it is a generic toolset. Originally focused only on PaX, it has been expanded to be generally security focused. It still has a good number of PaX helpers for people interested in that.
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.
