Updating the advisories
The advisories are actually in a separate GitHub repo, briandfoy/cpan-security-advisory that's a submodule of this repo. Follow the instructions for that repo to add or update advisories.
Updating the module
If you don't have the cpan-security-advisory directory, you need to set that up:
% perl Makefile.PL
% make submodules
If you already had the submodule, you may need to update it before you start work:
% git submodule update --remote
Once you have the submodule set up, you can regenerate lib/CPAN/Audit/DB.pm:
% make generate
