Package: bind9
Version: 1:9.6.1.dfsg.P1-3
Severity: critical
Tags: security
Hi.
I think this is quite security critical,... if my observations should
prove wrong, decrease than please priority ;)
When bind is configured to us TSIGs between master and slave when
tranferring a zone, via a
master 1.2.3.4 key somekey;
statement in a slave zone it should probably not accept such incoming
transfers from the master at 1.2.3.4 if somekey is no configured at
all in the local bind.
I does however:
Nov 6 01:10:05 kronecker named[21547]: zone example.com/IN: unable to
find key: a.example.net-b.example.net
Nov 6 01:10:05 kronecker named[21547]: zone example.com/IN: Transfer started.
I think this is quite critical as typos could easily happen, and bind
does not even refuse to start when a key that is referenced somewhere
wasn't declared.
Regards,
Chris.
Perhaps this should be sent to upstream, too.
