It means that you have portaudit installed, and it's run as part of
the daily scripts. That's a good thing.

I'd recommend consulting the portaudit man page

What it's found are packages on your machine that have security
bulletins against them - that is, the packages named have
vulnerabilities known to the FreeBSD Security team, which they believe
should be patched. There's a link to the bulletin for each one - I
think you'll find it enlightening to read some or all of them.

I'd do a 'pkg_add -r portupgrade' to install that package, do a cvsup
to get a current ports tree, then assess, very carefully, what you
want to upgrade. IMHO all of the packages mentioned should probably
get upgraded, unless you have *exceptional* reasons not to.

To upgrade you can do 'portupgrade <packagename>' for each package
named, or if you're feeling bold, 'portupgrade -aRr'.

Portupgrade will take care of dependencies. No worries, though you
should also peruse the man page for portupgrade to get your knowledge
up.

We were all novices - I still am, in far too many ways. Don't sweat
it, and keep asking questions. Also, start reading the FreeBSD
Handbook - it's online, and also downloadable, and covers this very
topic.
