- Fix that dnscrypt configuration does not crash, due to
inconsistency between secret and public keys. Also
duplicate files are skipped. Thanks to Qifan Zhang, Palo
Alto Networks, for the report.
- Fix that after malloc failure in RPZ load a half built
list does not crash later. The newly created RRset is
linked after creation has succeeded. Thanks to Qifan Zhang,
Palo Alto Networks, for the report.
- Fix that for a zonefile only zone, if that file does not
exist on server start, the server continues to start with
a warning log message. Thanks to Qifan Zhang, Palo Alto
Networks, for the report.
- Fix that a signed wildcard NSEC, is checked before use,
so it does not allow insecure DS proofs inappropriately.
Thanks to Qifan Zhang, Palo Alto Networks, for the report.
- Fix that auth-zone, and RPZ zones, do not allow out-of-zone
records. These are records that are not under the zone apex.
The out-of-zone records are dropped from the zone contents.
Thanks to Qifan Zhang, Palo Alto Networks, for the report.
- Fix that a half-written trust anchor file does not crash
the server at runtime. It unlinks a wrong file from the list.
Thanks to Qifan Zhang, Palo Alto Networks, for the report.
- Fix that when SVCB records cannot be written out, and
are written in unknown format, that the zone read allows
such unknown format SVCB records. Thanks to Qifan Zhang,
Palo Alto Networks, for the report.
- Fix to disallow $INCLUDE for secondary zones. Start up
of server continues if a secondary zone fails to load.
Failed loads clear the zone data, so there is no partial
zone. Thanks to Qifan Zhang, Palo Alto Networks, for
the report.
- Fix that dns64 bypasses rpz-passthru rule during
synthesis. This restricted more than necessary. Thanks to
Qifan Zhang, Palo Alto Networks, for the report.
- Fix misconfigured ipsecmod hook causing path name
similarity with other file. The ipsecmod is changed for
exec of the hook. The ipsecmod hook, if a script, has to
start now with a line like `#!/bin/sh`. Thanks to Qifan
Zhang, Palo Alto Networks, for the report.
- Fix DNAME synthesis from cache that keeps use of 0TTL
entries in a sliding window. It did not surpass RRSIG
expiry. Thanks to Qifan Zhang, Palo Alto Networks, for
the report.
- Fix erroneous DNS error report values after bogus AAAA
query caused error information that was not cleared by
a successful A subquery. Thanks to Qifan Zhang, Palo Alto
Networks, for the report.
- Fix for fast_reload that removes an auth zone while its
lookups are in progress, for a primary name. Also after the
change, it no longer picks up the old results. Thanks to
Qifan Zhang, Palo Alto Networks, for the report.
- Fix that fast_reload when a zonemd verification lookup
it in progress with subnet loaded, deregisters the
callback. Thanks to Qifan Zhang, Palo Alto Networks,
for the report.
- Fix perform a full transfer every number of incremental
transfers, to stop increasing memory usage, for auth-zone
and rpz zones. Thanks to Qifan Zhang, Palo Alto Networks,
for the report.
- Fix to add `max-transfer-size` and `max-transfer-time` that
limit auth-zone and rpz transfer amount and time taken.
Default is disabled. This hardens against unbounded
transfers. Thanks to Qifan Zhang, Palo Alto Networks,
for the report.
- Fix for #1306: configure detects specifically the call to
SSL_set_quic_tls_early_data_enabled and
SSL_set_quic_early_data_enabled, so the correct one is used.
- Fix that dns64 cleans up the allocated message if the adjust
routines fail, and checks if there is a reply before cache
store, also unbound checks if A and AAAA are malformed
for auth-zones. Thanks to Qifan Zhang, Palo Alto Networks,
for the report.
- Fix that dump_cache has a larger buffer for records,
and it checks that an owner name does not collide with BADRR
on the input, and changes verbosity on the log of failure in
rrset to string. Thanks to Qifan Zhang, Palo Alto Networks,
for the report.
- Fix that quotation and escaping works the same in auth-zone
url content, as in the zonefile read. Thanks to Qifan Zhang,
Palo Alto Networks for the report.
- Fix negative cache to work with NSEC3 records without salt.
Thanks to Xin Wang, Jiapeng Li, and Jiajia Liu, Northwestern
Polytechnical University, for the report.
- Fix that the processing of class responses does not have
a heap use-after-free. That could happen if at least two
distinct classes are configured for resolution. Thanks
to Qifan Zhang, Palo Alto Networks for the report.
In addition, thanks to Xin Wang, Jiapeng Li, and Jiajia
Liu, Northwestern Polytechnical University, for also
reporting this.
- Fix that validator caps number of ANY RRsets it can
validate, and the wait timer is shortened. Thanks to Qifan
Zhang, Palo Alto Networks, for the report.
- Fix ipset module for name too long checks, race conditions
on local name buffer, and for socket close race condition.
Thanks to Qifan Zhang, Palo Alto Networks, for the report.
- Fix manual to document ratelimit, that it is for target
nameservers for a domain, and keeps queries limited. Thanks
to Qifan Zhang, Palo Alto Networks, for the report.
- Fix for mesh new client and mesh new callback to rollback the
added address, tcp mesh state and callback when there is a failure
to initialize. This fixes the mesh accounting of reply addresses.
Thanks to Xin Wang, Jiapeng Li, and Jiajia Liu, Northwestern
Polytechnical University, for the report
- Fix for signed same-owner CNAME and ordinary RRset responses.
Thanks to Xin Wang and Jiajia Liu, Northwestern Polytechnical
University, for the report.
