Re: Will Oracle Security Alert for CVE-2012-1675 non-RAC fixes work with CMAN, etc?

yes, at the moment you make sure DST= _only_ points to the hosts which are expected to serve SRV, you are protected. In fact there is a little hole, where someone hijacks the DB-Server host and instead of attacking the DB directly hijacking the CMAN. But I'd say in this case there are bigger problems than CMAN.
In the Note mentioned "node1" is the "good one" and "node2" the "hijacker". If you want to save a CMAN which serves a service from a RAC, you should add all Listener-IPs of this RAC. (I'd guess only the hostname-VIP are enough, but I never tested this into details).
I'd say 12880299 is not needed for CMAN at all. if your OID has it's own listener, apply it in the home for this listener.
