The Comprehensive Perl Archive Network (CPAN) is a very useful collection of Perl code. It has several indices of the files that it hosts, including a file named "02packages.details.txt.gz" in the "modules" directory. This file contains lots of useful information and the Perl 5 module Parse::CPAN::Packages provides a simple interface to the data contained within.
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.
