New DNSSEC Root Key
ICANN is in the process of introducing a new Key Signing Key (KSK) for
the global root zone. BIND has multiple methods for managing DNSSEC
trust anchors, with somewhat different behaviors. If the root key is
configured using the managed-keys statement, or if the pre-configured
root key is enabled by using dnssec-validation auto, then BIND can keep
keys up to date automatically. Servers configured in this way will roll
seamlessly to the new key when it is published in the root zone.
However, keys configured using the trusted-keys statement are not
automatically maintained. If your server is performing DNSSEC
validation and is configured using trusted-keys, you are advised to
change your configuration before the root zone begins signing with the
new KSK. This is currently scheduled for October 11, 2017.
This release includes an updated version of the bind.keys file
containing the new root key. This file can also be downloaded from
https://www.isc.org/bind-keys .
Security Fixes
* The BIND installer on Windows used an unquoted service path, which
can enable privilege escalation. This flaw is disclosed in
CVE-2017-3141. [RT #45229]
* With certain RPZ configurations, a response with TTL 0 could cause
named to go into an infinite query loop. This flaw is disclosed in
CVE-2017-3140. [RT #45181]
End of Life
The end of life for BIND 9.10 is yet to be determined but will not be
before BIND 9.12.0 has been released for 6 months.
