portaudit provides a list of published security vulnerabilities

of FreeBSD ports and tools to check if installed ports are listed.

Since this is a prerelease version, it is mostly usable for
committers that want to contribute to the project, and can currently
not be relied upon as an extensive security auditing tool.
