hmm, i still cannot get how "network adjacent" is related to root
privileges. But my head never was good for attacks...

Another thing, which is out of my head, is that discussion about
validating of DNS responses in resolvers ended at "unknown" query
types. But exim's dnsdb allows only limited, well known, types, thus
"unknown" types are unrelated.

BTW, Heiko, i see that discussion with ZDI "continue" on oss-security.
Please, can you from time to time post summary here?

regards
