Thanks for taking the time to report this bug and make Ubuntu better.
This issue seems to affect only people who are compiling their own versions of exim4. For this reason, the security doesn't plan to act on it. I've subscribed the Ubuntu Server team to this bug, and will set the priority to Low. Unfortunately this usually means that we won't have the time to work on this bug, but given that you have already come up with a patch/workaround for the problem, I think this is mostly fine.
