portaudit: recommended packages can't be installed

[Robert S]

8I've just started playing around with FreeBSD.  One of my main
priorities of an OS is ease of upgrading.  If I run portaudit, I get a
list of insecure packages (here is an excerpt from the output):

Affected package: firefox-1.0.3,1
Type of problem: mozilla -- code execution via javascript: IconURL
vulnerability.
Reference: <http://www.FreeBSD.org/ports/portaudit/eca6195a-c233-11d9-804c-02061b08fc24.html>

Affected package: kdelibs-3.4.0_1
Type of problem: kdelibs -- kimgio input validation errors.
Reference: <http://www.FreeBSD.org/ports/portaudit/06404241-b306-11d9-a788-0001020eed82.html>

4 problem(s) in your installed packages found.

You are advised to update or deinstall the affected package(s) immediately.

If I try to replace kdelibs with a binary package, or install it
through ports (after doing a cvsup), I still get verion 3.4.0_1.

Are fixes not necessarily made available when security vulnerabilities
are found?

Also -- is there a similar utility to portaudit and freebsd-update,
that can be used on the base operating system (not through ports)?
