one possibility is to apply the security patches you need to 2.0.50 see http://apache.towardex.com/httpd/patches/apply_to_2.0.50/
the descriptions of the vulnerabilities at http://httpd.apache.org/ indicate which components are affected; note that CAN-2004-0786 applies to all configurations; I have seen a suggestion that it affects IPv6 setups only, but that is not the case
