the problems related to the handling of broken DNSSEC trust chains.
This fix is only relevant for those who have DNSSEC validation
enabled and configure trust anchors from third parties, either
manually, or through a system like DLV.
Update to BIND 9.6.1-P2. The vulnerability this is designed to fix is
related to DNSSEC validation on a resolving name server that allows
access to untrusted users. If your system does not fall into all 3 of
these categories you do not need to update immediately.
lots of new features compared to 9.4.x, including:
Full NSEC3 support
Automatic zone re-signing
New update-policy methods tcp-self and 6to4-self
DHCID support.
More detailed statistics counters including those supported in BIND 8.
Faster ACL processing.
Efficient LRU cache-cleaning mechanism.
NSID support.
