1. Very large RRSIG RRsets included in a negative cache can trigger
an assertion failure that will crash named (BIND 9 DNS) due to an
off-by-one error in a buffer size check.
This bug affects all resolving name servers, whether DNSSEC validation
is enabled or not, on all BIND versions prior to today. There is a
possibility of malicious exploitation of this bug by remote users.
2. Named could fail to validate zones listed in a DLV that validated
insecure without using DLV and had DS records in the parent zone.
Add a patch provided by ru@ and confirmed by ISC to fix a crash at
shutdown time when a SIG(0) key is being used.
security patches to the 9.6.1 version, as well as many other bug fixes.
This version also incorporates a different fix for the problem we had
patched in contrib/bind9/bin/dig/dighost.c, so that file is now back
to being the same as the vendor version.
Due to the fact that the DNSSEC algorithm that will be used to sign the
root zone is only included in this version and in 9.7.x those who wish
to do validation MUST upgrade to one of these prior to July 2010.
changes from the 9.6.1rc1 version. The first 2 only affect DNSSEC.
named could incorrectly delete NSEC3 records for
empty nodes when processing a update request.
Accept DS responses from delegation only zones.
"delegation-only" was not being accepted in
delegation-only type zones.
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.
