xcb-util-errors is a utility library that gives human readable names to error codes and event codes and also to major and minor numbers. The necessary information is drawn from xcb-proto's protocol descriptions. This library is especially useful when working with extensions and is mostly useful for debugging.
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.
