Override FORBIDDEN ports?

[Indigo 23]

I was trying to recompile mozilla (www/mozilla), but I cannot because
it gives me this error:

"===>  mozilla-1.7.13_1,2 has known vulnerabilities:
=> mozilla -- multiple vulnerabilities.
   Reference: <http://www.FreeBSD.org/ports/portaudit/e6296105-449b-11db-ba89-000c6ec775d9.html>
=> mozilla -- multiple vulnerabilities.
   Reference: <http://www.FreeBSD.org/ports/portaudit/e2a92664-1d60-11db-88cf-000c6ec775d9.html>
=> Please update your ports tree and try again.
*** Error code 1

Stop in /usr/ports/www/mozilla."

My question is how to bypass this and force it to compile/install?

Thanks.
