The Quota module provides access to file system quotas. The quotactl system call or ioctl or libquota is used to query or set quotas on the local host, or queries are submitted via RPC to a remote host. Mount tables can be parsed with getmntent and paths can be translated to device files (or whatever the actual quotactl implementations needs as argument) of the according file system.
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.
Problem reports, updates or suggestions for this package should be reported with send-pr.
