Suggestion from Qalys:
If I may add one more thing, there is an issue that should be addressed sooner rather than later: the writable configuration at the beginning of the heap. A short-term (and hopefully non-intrusive) solution may be to mmap() the configuration instead, and then mprotect(PROT_READ) it. This would mitigate the exploitation technique that almost all Exim exploits have been using.
