Kpathsea is a library to do path searching. It is used in the Web2C implementation of TeX and friends. The library's fundamental purpose is to return a filename from a list of directories specified by the user, similar to what shells do when looking up program names to execute.
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.
