there is no "definitely stable and verified with ages versions"
for any non trivial piece of code.
"verified with ages" just means it works fine for all inputs encountered
and likely will continue to do so as long as nothing major changes in the
that doesnt say what will happen if someone reads the code and constructs
specific input for an exploit or what will happen when someone tries
an exploit from the leading edge version against the old code.
In practice IMHO, your best hope with old software is that an attacker
will fail to guess the exact version and thus a few addresses in her
exploit will be off and it will just crash your server.
And of course chances are your server is not important enough for
anyone to invest more than a little time.
It might be different if all securty fixes where backported to old
versions but that just doesnt happen for anything for which ive followed
This though would still require you to regularly update to the patched
versions (which if i understood you correctly you cant do before febuary)
