LaTeX's standard styles use two page styles, one on normal pages and one on 'opening' pages with \maketitle or \chapter, etc. Unfortunately there is only easy access to changing one of these two so if you want something other than 'plain' on the opening pages you must use \thispagestyle on each such page. The fancyhdr package does provide a more flexible interface, but if you just want an empty page style on all pages then this package will do the job.
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.
