A simple question about patches for FreeBSD from http://security.freebsd.org/patches

[PowerMan]

 Dear sir,
      My first language is not English, please forgive me if I made some bad
words. And I do not know if that is the right e-mail address to ask
questions.

     I copy a few lines from http://security.freebsd.org/

   - FreeBSD-SA-07:05.libarchive.asc<http://security.freebsd.org/advisories/FreeBSD-SA-07:05.libarchive.asc>
   - FreeBSD-SA-07:04.file.asc<http://security.freebsd.org/advisories/FreeBSD-SA-07:04.file.asc>

   - FreeBSD-SA-07:02.bind.asc<http://security.freebsd.org/advisories/FreeBSD-SA-07:02.bind.asc>

FreeBSD 6.2-RELEASE released.

   - FreeBSD-SA-07:01.jail.asc<http://security.freebsd.org/advisories/FreeBSD-SA-07:01.jail.asc>

FreeBSD 5.5-RELEASE released.

Is that mean if I use 5.5-release, I should apply all the patches above and

if I use 6.2-release I need only apply the
FreeBSD-SA-07:05.libarchive.asc<http://security.freebsd.org/advisories/FreeBSD-SA-07:05.libarchive.asc>
to
FreeBSD-SA-07:02.bind.asc<http://security.freebsd.org/advisories/FreeBSD-SA-07:02.bind.asc>
?

Is that right?

Thanks.
