This is a rather incomplete implementation of work done by Gudrun Putze-Meier. I have to confess that I never read her original paper. So all credit belongs to her, all bugs are mine. I tried to get some insight from an implementation of two students of mine. They remain anonymous because their work was the wost piece of code I ever saw. My code behaves mostly as their implementation did except it is about 75 times faster.
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.
