Subject Re: [users@httpd] Apache 1.3 and OpenSSL
Date Wed, 09 Nov 2005 16:14:44 GMT
<oops - have switched Gmail to plain text now>

Each of the versions of Apache/mod_ssl/OpenSSL that I'm using have
been periodically updated with essential security updates (so while
it's Apache 1.3.12 as a baseline, it's not quite that ancient). 
However, it can be hard to tell exactly *which* patches have been

You're completely right, though - this is a horrible situation :-)

What I've really been looking for is some kind of statement that
OpenSSL version X is only compatible with mod_ssl version X (and
later).  Like I said before, I know that Apache and mod_ssl are
closely tied together, but have never seen anything that notes the
'dependencies' between Apache/mod_ssl and OpenSSL.

Thanks for your response.

as far as 0.9.5a - that is, there are various function calls in mod_ssl 2.6.6 which expect
to be understood by the OpenSSL library. If the interface to the library has changed at all
since April 2000, the answer will be "no" (I'd be astonished if it is "yes").

only ancient (July 2000), by comparison with a modern version, it is buggy and insecure. You
are doing no-one a favour by keeping it on the internet. Rather than pottering about trying
to fit a hydrogen fuel cell to a Morris 1000 Traveller, I would invest the effort in modifying
whatever application that forces you to use apache 1.3.12 so you can upgrade apache to a recent
