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.
