The failure path now goes through the same + cleanup label as every other error. :gl:`#5913` :gl:`!11919` + +- Prevent rare named crash when notifies are cancelled. ``49509dcbae`` + + Under heavy load, named could occasionally crash when a queued + outbound notify or zone refresh was cancelled at the moment it was + being sent — for example, while a zone was being reloaded or removed. + The race that caused the crash is now prevented. :gl:`#5915` + :gl:`!11922` + +- Stop delv from aborting on a malformed query name. ``ca8315bb4d`` + + delv aborts with SIGABRT instead of exiting cleanly when given a query + name that fails wire-format conversion (e.g. a label longer than 63 + octets).

This has been fixed. :gl:`#5938` :gl:`!11966` + +- Fix a bug in allow-query/allow-transfer catalog zone custom + properties. ``e962fd459e`` + + The :iscman:`named` process could terminate unexpectedly when + processing a catalog zone with an invalid ``allow-query`` or + ``allow-transfer`` custom property (i.e. having a non-APL type) + coexisting with the valid property. This has been fixed. :gl:`#5941` + :gl:`!11975` + +- Fix a stack use-after-free in qpzone. ``ddea991c07`` + + In previous_closest_nsec(), a new qpreader was opened to search the + NSEC tree. It was possible for that to be used to update a QP iterator + object owned by the caller, and then be destroyed when the function + returned. + + This has been addressed by having the caller open the NSEC qpreader + instead. :gl:`#5942` :gl:`!11956` + +- Fix a memory leak issue in the catalog zones. ``5fcb6d8809`` + + The :iscman:`named` process could leak small amounts of memory when + processing a catalog zone entry which had defined custom primary + servers with TSIG keys using both the regular ``primaries`` custom + property syntax and the legacy alternative syntax (``masters``) at the + same time. This has been fixed. :gl:`#5943` :gl:`!11973` + +- Fix suppressed missing-glue check in named-checkzone. ``dc5eb3fe25`` + + named-checkzone and named-checkconf -z silently skipped the + missing-glue check for any NS name that had already triggered an + extra-AAAA-glue warning, so zones missing required A glue could pass + validation and be deployed with broken delegations. :gl:`!11905` + +- Implement seamless outgoing TCP connection reuse. ``eb117e16b9`` + + The resolver can and will reuse outgoing TCP connections to the same + host, as recommended by RFC 7766.

Addresses in + the resolver's server list are now deduplicated so that each unique IP is only + queried once per resolution attempt, regardless of how many NS records + point to it. The number of addresses stored per nameserver name + is also now capped at six (combined A and AAAA), preventing memory and CPU overhead from + domains with unusually large NS/glue sets. + + ISC would like to thank Shuhan Zhang from Tsinghua University for + reporting this issue. :gl:`#5641` + +- Fix GSS-API resource leak. :cve:`2026-3039` + + A memory leak was fixed where each GSS-API TKEY negotiation leaked a + security context inside the GSS library. An unauthenticated attacker + could exhaust server memory by sending repeated TKEY queries to a + server with :any:`tkey-gssapi-keytab` configured. The leaked memory was + allocated by the GSS library, bypassing BIND's memory accounting. + + Multi-round GSS-API negotiation (GSS_S_CONTINUE_NEEDED) is now + rejected, as BIND never supported it correctly and Kerberos/SPNEGO + completes in a single round. + + ISC would like to thank Vitaly Simonovich for bringing this + vulnerability to our attention. :gl:`#5752` + +- Disable recursion, UPDATE, and NOTIFY for non-IN views. + :cve:`2026-5946` + + Recursion, dynamic updates (UPDATE), and zone change notifications + (NOTIFY) are now disabled for views with a class other than IN (such + as CHAOS or HESIOD); authoritative service for non-IN zones (e.g. + version.bind in class CHAOS) continues to work as before. Servers + configured with :namedconf:ref:`recursion yes; ` + in a non-IN view log a warning at + startup, and :iscman:`named-checkconf` flags the same condition. UPDATE and + NOTIFY messages that specify the meta-classes ANY or NONE in the + question section are now rejected with FORMERR. + + This addresses a set of closely related security issues collectively + identified as CVE-2026-5946. ISC would like to thank Mcsky23 for + bringing these issues to our attention. :gl:`#5784` + +- Avoid unbounded recursion loop. :cve:`2026-5950` + + A bug during bad server handling could cause the resolver to enter an + infinite loop, continuously sending queries to an upstream server with + no exit condition, until the resolver query timeout was hit. This has + been fixed. + + ISC would like to thank Billy Baraja (BielraX) for bringing this issue + to our attention. :gl:`#5804` + +- Fix crash in resolver when SIG(0)-signed responses are received under + load. :cve:`2026-5947` + + A resolver could crash when handling a SIG(0)-signed response if the + matching client query was cancelled while signature verification was + still in progress — for example, when the recursive-clients quota was + exhausted. This has been fixed. + + ISC would like to thank Naoki Wakamatsu for bringing this + vulnerability to our attention. :gl:`#5819` + +- Fix use-after-free error in DNS-over-HTTPS when processing HTTP/2 + SETTINGS frames. :cve:`2026-3593` + + Previously, a use-after-free vulnerability in the DNS-over-HTTPS implementation + could cause :iscman:`named` to crash when a client sent a flood of HTTP/2 + SETTINGS frames while a DoH response was being written. This affected + servers with DoH (DNS-over-HTTPS) enabled and has been fixed. + + ISC would like to thank Naresh Kandula Parmar (Nottiboy) for reporting + this. :gl:`#5755` + +- Fix outgoing zone transfers' quota issue. + + Unauthorized clients could consume the entire outgoing zone-transfer quota and + block authorized zone transfer clients. This has been fixed. + :gl:`#3589` + +Feature Changes +~~~~~~~~~~~~~~~ + +- Fix CPU spikes and slow queries when cache approaches memory limit. + + Cache cleanup is now spread probabilistically to avoid CPU usage spikes and a + drop in query throughput. :gl:`#5891` + +Bug Fixes +~~~~~~~~~ + +- Use the zone file's basename as origin in DNSSEC tools. + + In :iscman:`dnssec-signzone` and :iscman:`dnssec-verify`, when the zone origin is not + specified using the ``-o`` parameter, the default behavior is to try to + sign using the zone's file name as the origin. So, for example, + ``dnssec-signzone -S example.com`` will work, so long as the file name + matches the zone name. + + This now also works if the zone is in a different directory. For + example, ``dnssec-signzone -S zones/example.com`` will set the origin + value to ``example.com``. :gl:`#5678` + +- Fix a possible race condition during zone transfers. + + The :iscman:`named` process could terminate unexpectedly when + processing an IXFR message during a zone transfer. This has been + fixed. :gl:`#5767` + +- Fix :iscman:`named` crash when processing SIG records in dynamic updates. + + Previously, :iscman:`named` could abort if a client sent a dynamic + update containing a SIG record (the legacy signature type) to a zone + configured with an update-policy. The function `dns_db_findrdataset` + had an incorrect requirements prerequisite that prevented SIG records + from being looked up, which was triggered as part of processing an UPDATE + request and could be triggered remotely by any client permitted to + send updates. This has been fixed by ensuring that SIG records are + handled consistently with RRSIG records during update processing. + :gl:`#5818` + +- Fix :option:`rndc modzone` behavior for a zone in named.conf. + + If a zone was present in the configuration file and not originally + added by :option:`rndc addzone`, :option:`rndc modzone` for that zone would succeed + once but subsequent :option:`rndc modzone` attempts would fail. This has been + fixed. :gl:`#5826` + +- Fix zone verification of NSEC3 signed zones. + + Previously, when computing the compressed bitmap during verification + of an NSEC3-signed zone, an undersized buffer was used that resulted + in an out-of-bounds write if there were too many active windows in the + bitmap. This impacted the mirror zones which are NSEC3-signed, + :iscman:`dnssec-signzone` and :iscman:`dnssec-verify`. This has been fixed. + :gl:`#5834` + +- Prevent a crash when using both :any:`dns64` and :any:`filter-aaaa`. + + An assertion failure could be triggered if both :any:`dns64` and the + :any:`filter-aaaa` plugin were in use simultaneously. This happened if the + plugin triggered a second recursion process, which then attempted to + store DNS64 state information in a pointer that had already been set + by the original recursion process. This has been fixed. :gl:`#5854` + +- Fixed an assertion failure when processing catalog zones. + + If a TXT record containing an invalid name TSIG key name was found + when processing a catalog zone member's primaries definition, + ``dns_name_free`` was incorrectly called, triggering an assertion. This has + been fixed. :gl:`#5858` + +- Prevent malicious DNSSEC zones from exhausting validator CPU. + + A DNSSEC-signed zone could publish a DNSKEY with an unusually large + RSA public exponent and force any validator resolving names in that + zone to spend disproportionate CPU verifying signatures. The + validator now rejects such DNSKEYs, matching the limit already applied + to keys read from files or HSMs. :gl:`#5881` + +- Fix :iscman:`rndc-confgen` aborting on HMAC-SHA-384/512 keys above 512 bits. + + :iscman:`rndc-confgen` (with either ``-A hmac-sha384`` or + ``-A hmac-sha512``) previously documented a ``-b`` + range of 1..1024, but any value above 512 aborted on hardened builds + instead of producing a key. The full advertised range now works. + :gl:`#5903` + +- Prevent crafted queries from degrading RRL performance. + + With response rate limiting enabled, an attacker sending queries from + many spoofed source addresses could steer entries into the same slot + of the internal rate-limit table and slow down query processing on the + affected server. The table now uses a per-process keyed hash so the + placement of entries cannot be predicted or influenced from the + network. :gl:`#5906` + +- Prevent rare :iscman:`named` crash when notifies are cancelled. + + Under heavy load, :iscman:`named` could occasionally crash when a queued + outbound notify or zone refresh was cancelled at the moment it was + being sent — for example, while a zone was being reloaded or removed. + The race that caused the crash is now prevented. :gl:`#5915` + +- Stop :iscman:`delv` from aborting on a malformed query name. + + :iscman:`delv` previously aborted with SIGABRT instead of exiting cleanly when given a query + name that failed wire-format conversion (e.g. a label longer than 63 + octets). After this change :iscman:`delv` prints the parse error and exits with + a normal failure code. :gl:`#5916` + +- Fix a crash when reconfiguring while an NTA is being rechecked. + + Previously, if :iscman:`named` was reconfigured or shut down while a negative trust anchor + was being rechecked against authoritative servers, the in-flight + recheck could outlive the view that owned it and cause :iscman:`named` to + crash. This has been fixed. :gl:`#5938` + +- Fix a bug in :any:`allow-query`/:any:`allow-transfer` catalog zone custom + properties. + + The :iscman:`named` process could terminate unexpectedly when + processing a catalog zone with an invalid :any:`allow-query` or + :any:`allow-transfer` custom property (i.e. having a non-APL type) + coexisting with the valid property. This has been fixed. :gl:`#5941` + +- Fix a memory leak issue in catalog zones. + + The :iscman:`named` process could leak small amounts of memory when + processing a catalog zone entry which had defined custom primary + servers with TSIG keys, if both the regular ``primaries`` custom + property syntax and the legacy alternative syntax (``masters``) were used at the + same time. This has been fixed. :gl:`#5943` + +- Fix suppressed missing-glue check in :iscman:`named-checkzone`. + + :iscman:`named-checkzone` and :option:`named-checkconf -z` silently + skipped the missing-glue check for any NS name that had already + triggered an extra-AAAA-glue warning, so zones missing required A glue + could pass validation and be deployed with broken delegations. + :gl:`!11899` + +- Implement seamless outgoing TCP connection reuse. + + The resolver can and will reuse outgoing TCP connections to the same + host, as recommended by :rfc:`7766`. This prevents a whole class of + attacks that abuse the fact that establishing a TCP connection is + expensive and it is fairly easy to deplete the outgoing TCP ports by + putting them into ``TIME_WAIT`` state. + + The number of pipelined queries per connection is capped at 256 to + limit the impact of a connection drop. :gl:`!11845` + +- Reject record sets too large to serve in DNS. + + When BIND was asked to store a record set whose total size exceeded + what fit in a DNS message, it would allocate memory and build the + structure, then fail later at response time. Such oversized record + sets are now rejected at the time of storage with an error, avoiding + wasted work on data that can never be served. :gl:`!11963` + + diff --git a/lib/dns/adb.c b/lib/dns/adb.c index 00471556..7bfafff6 100644 --- a/lib/dns/adb.c +++ b/lib/dns/adb.c @@ -78,6 +78,15 @@ #define DNS_ADB_MINADBSIZE (1024U * 1024U) /*%< 1 Megabyte */ +/* + * Default and override for the per-find address limit, the sum of the number of + * A and AAAA RR from an ADB NS name resolution.
