The remote web server appears to be running a version of Apache that is older
than version 1.3.32.

This version is vulnerable to a heap based buffer overflow in proxy_util.c
for mod_proxy. This issue may lead remote attackers to cause a denial of 
service and possibly execute arbitrary code on the server.

Solution: Don't use mod_proxy or upgrade to a newer version.
Risk factor: Medium";
