release-1.23.1
5bf82f24 · ·Unbound 1.23.1 This security release fixes the Rebirthday Attack CVE-2025-5994. This re-opens up resolvers to a birthday paradox, for EDNS client subnet servers that respond with non-ECS answers. It only affects Unbound when compiled with --enable-subnet, and subnetmod is enabled with config options that send ECS information to upstream servers. The CVE is described here https://nlnetlabs.nl/downloads/unbound/CVE-2025-5994.txt We would like to thank Xiang Li (AOSP Lab, Nankai University) for discovering and responsibly disclosing the vulnerability. Bug Fixes: - Fix RebirthDay Attack CVE-2025-5994, reported by Xiang Li from AOSP Lab Nankai University.

release-1.23.0
30c13d03 · ·Unbound 1.23.0 This release features changed defaults, fast reload, redis replica, DNS Error Reporting, and bug fixes. The fast reload is a feature that is listed as experimental. With `unbound-control fast_reload` the server can read the new config in a thread, and when done only briefly pauses the server to update the settings. This uses double memory, for like zones from disk or config that is loaded. It only pauses the server, for like less than a second, so DNS service is not interrupted by the reload of config. A lot of config items can be changed, but not all. It has options to print more information, or memory usage, and there is a list of config options in the man page. The redis replica support allows for a redis backend to use a redis replica. The read commands are sent to the redis replica host, while the write commands are sent to the redis server. So with several replicas there can be more readers that all write to the redis server. With DNS error reporting, RFC9567, enabled with `dns-error-reporting: yes`, this uses the error reporting agent to send failure reports to. The number of error reporting queries is output in the statistics as `num.dns_error_reports`. Some defaults are changed in this release. The `resolver.arpa.` and `service.arpa.` zones are added to the default locally served zones, this can be disabled with a nodefault local zone. The default for `max-global-quota` has changed to 200, after operational feedback. The defaults from RFC8767 are used by `serve-expired-client-timeout` on 1800 milliseconds and `serve-expired-ttl` on 86400 seconds. If Unbound is compiled with edns subnet, the default for module-config is no longer altered, so that compilation with subnet does not interfere when the server does not use subnet. When edns subnet needs to be enabled, `module-config: "subnetcache validator iterator"` should be explicitly set as configuration in the `server:` section. If edns subnet is enabled, the default for module-config is no longer altered, so that compilation with subnet does not interfere when the server does not use subnet. When edns subnet is in use, also `module-config: "subnetcache validator iterator"` should be set as configuration in the `server:` section. The RC2 has fixes for building on Solaris and portability to Windows, and fixes a memory leak for DoH. Features - Increase the default of max-global-quota to 200 from 128 after operational feedback. Still keeping the possible amplification factor (CAMP related issues) in the hundreds. - Fix #1175: serve-expired does not adhere to secure-by-default principle. The default value of serve-expired-client-timeout is set to 1800 as suggested by RFC8767. - For #1175, the default value of serve-expired-ttl is set to 86400 (1 day) as suggested by RFC8767. - For #1207: [FR] Support for RESINFO RRType 261 (RFC9606), add LDNS_RR_TYPE_RESINFO similar to LDNS_RR_TYPE_TXT. - Add resolver.arpa and service.arpa to the default locally served zones. - Merge #1042: Fast Reload. The unbound-control fast_reload is added. It reads changed config in a thread, then only briefly pauses the service threads, that keep running. DNS service is only interrupted briefly, less than a second. - Merge #1019: Redis read-only replica support. Introduces new 'redis-replica-*' options for the Redis cache backend. - Merge #902: DNS Error Reporting (RFC 9567). Introduces new configuration option 'dns-error-reporting' and new statistics for 'num.dns_error_reports'. Bug Fixes - Fix #1154: Tag Incorrectly Applying for Other Interfaces Using the Same IP. This fix is not for 1.22.0. - Fix #1163: Typos in unbound.conf documentation. - Merge #1159: Stats for discard-timeout and wait-limit. - Add test case for #1159. - Some clean up for stat_values.test. - Merge #1170 from Melroy van den Berg, Fix chroot manpage description. - Merge #1157 from Liang Zhu, Fix heap corruption when calling ub_ctx_delete in Windows. - Fix redis that during a reload it does not fail if the redis server does not connect or does not respond.

release-1.22.0
0076736f · ·Unbound 1.22.0 This release has an option to harden against unverified glue, it is enabled with `harden-unverified-glue: yes`. It was contributed by Karthik Umashankar from Microsoft. This protects Unbound against bad glue, that is out of zone, by performing a lookup for it. Because it uses the original information as a last resort if nothing works, it should not give lookup failures, and add protection. There are options to configure the scrubbing for NS records and the CNAME scrubbing and the max global quota lookup limit from previous security fix releases. They can be configured with the options `iter-scrub-ns`, `iter-scrub-cname` and `max-global-quota`. For redis use, with cachedb, it is possible to specify the timeout for the initial connection separately from the timeout for commands. With the options `redis-command-timeout: 20` and `redis-connect-timeout: 200` they can be set separately, for a longer connect attempt, but a short command timeout to keep resolution faster. It is possible to log with ISO8601 format with `log-time-iso: yes` this also logs time in milliseconds. Useful if the server writes to file, syslog may have its own format. DNS over QUIC is support is added, if compiled with libngtcp2 and with the openssl+quic that it uses. Use `--with-libngtcp2` for that, and enable it with `quic-port: 853`. There is a post about it on https://blog.nlnetlabs.nl/dns-over-quic-in-unbound [that is to appear after the release]. Features - Add iter-scrub-ns, iter-scrub-cname and max-global-quota configuration options. - Merge patch to fix for glue that is outside of zone, with `harden-unverified-glue`, from Karthik Umashankar (Microsoft). Enabling this option protects the Unbound resolver against bad glue, that is unverified out of zone glue, by resolving them. It uses the records as last resort if there is no other working glue. - Add redis-command-timeout: 20 and redis-connect-timeout: 200, that can set the timeout separately for commands and the connection set up to the redis server. If they are not specified, the redis-timeout value is used. - Fix #1144: [FR] log timestamps in ISO8601 format with timezone. This adds the option `log-time-iso: yes` that logs in ISO8601 format. - Merge #871: DNS over QUIC. This adds `quic-port: 853` and `quic-size: 8m` that enable dnsoverquic, and the counters `num.query.quic` and `mem.quic` in the statistics output. The feature needs to be enabled by compiling with libngtcp2, with `--with-libngtcp2=path` and libngtcp2 needs openssl+quic, pass that with `--with-ssl=path` to compile unbound as well. Bug Fixes - Fix #1126: unbound-control-setup hangs while testing for openssl presence starting from version 1.21.0. - Add cross platform freebsd, openbsd and netbsd to github ci. - Fix for char signedness warnings on NetBSD. - Fix #1127: error: "memory exhausted" when defining more than 9994 local-zones. - Fix documentation for cache_fill_missing function. - Fix #1130: Loads of logs: "validation failure: key for validation <domain>. is marked as invalid because of a previous" for non-DNSSEC signed zone. - Fix that when rpz is applied the message does not get picked up by the validator. That stops validation failures for the message. - Fix that stub-zone and forward-zone clauses do not exhaust memory for long content. - Unit test for auth zone transfer TLS, and TLS failure. - Fix to print port number in logs for auth zone transfer activities. - Merge #1132: b.root renumbering. - Fix for #1132, adjusted unit test for change in the test file. - Fix for #1132, comment about adjusted copy of reference check. - Merge #1135: Add new IANA trust anchor. - Fix config file read for dnstap-sample-rate. - Fix alloc-size and calloc-transposed-args compiler warnings. - Fix comment to not trigger doxygen unknown command. - Fix to limit NSEC and NSEC3 TTL when aggressive nsec is enabled (RFC9077). - Add unit test for ttl limit for aggressive nsec. - Fix and add comments in testdata/val_negcache_ttl.rpl. - Merge #1140: Fix spelling mistake in comments. - Fix doxygen warnings by commenting out CLANG_ASSISTED_PARSING, CLANG_ADD_INC_PATHS, CLANG_OPTIONS and CLANG_DATABASE_PATH; they were already disabled. - Fix dns64 with prefetch that the prefetch is stored in cache. - Attempt to further fix doh_downstream_buffer_size.tdir flakiness. - More clear text for prefetch and minimal-responses in the unbound.conf man page. - Merge #1143: Fix cache update when serve expired is used. Expired records are favored over resolution and validation failures when serve-expired is used. - Fix negative cache NSEC3 parameter compares for zero length NSEC3 salt. - Fix unbound dnstap socket test program analyzer warnings about unused variable assignments and variable initialization. - Fix #1149: unbound-control-setup hangs sometimes depending on the openssl version. - Fix #1128: Cannot override tcp-upstream and tls-upstream with forward-tcp-upstream and forward-tls-upstream. - Fix to limit NSEC TTL for messages from cachedb. Fix to limit the prefetch ttl for messages after a CNAME with short TTL. - Fix for dnstap compile of doqclient with doq disabled. - Fix cookie_file test sporadic fails for time change during the test. - Fix add reallocarray to alloc stats unit test, and disable override of strdup in unbound-host, and the result of config get option is freed properly. - Fix to disable detection of quic configured ports when quic is not compiled in. - Fix harden-unverified-glue for AAAA cache_fill_missing lookups. - Fix contrib/aaaa-filter-iterator.patch for change in call signature for cache_fill_missing. - Fix to display warning if quic-port is set but dnsoverquic is not enabled when compiled. - Fix dnsoverquic to extend the number of streams when one is closed. - Fix for dnstap with dnscrypt and dnstap without dnsoverquic. - Fix for dnsoverquic and dnstap to use the correct dnstap environment.

release-1.21.1
b7c61d7c · ·Unbound 1.21.1 This security release fixes CVE-2024-8508. A vulnerability has been discovered in Unbound when handling replies with very large RRsets that Unbound needs to perform name compression for. Malicious upstreams responses with very large RRsets can cause Unbound to spend a considerable time applying name compression to downstream replies. This can lead to degraded performance and eventually denial of service in well orchestrated attacks. The vulnerability can be exploited by a malicious actor querying Unbound for the specially crafted contents of a malicious zone with very large RRsets. Before Unbound replies to the query it will try to apply name compression which was an unbounded operation that could lock the CPU until the whole packet was complete. Unbound version 1.21.1 introduces a hard limit on the number of name compression calculations it is willing to do per packet. Packets that need more compression will result in semi-compressed packets or truncated packets, even on TCP for huge messages, to avoid locking the CPU for long. This change should not affect normal DNS traffic. We would like to thank Toshifumi Sakaguchi for discovering and responsibly disclosing the vulnerability. Bug Fixes: - Fix CVE-2024-8508, unbounded name compression could lead to denial of service.

release-1.21.0
79e4c578 · ·Unbound 1.21.0 This release has a fix for the CAMP and CacheFlush issues. They have a low severity for Unbound, since it does not affect Unbound so much. The Compositional Amplification (CAMP) type of attacks can lead to DoS attacks against DNS servers. In Unbound legitimate client requests to the resolvers under typical workload are not directly affected by CAMP attacks. However we introduce a global quota for 128 outgoing packets per query (and it's subqueries) that is never reset to prevent the combination of CAMP with other amplification attacks in the future. We would like to thank Huayi Duan, Marco Bearzi, Jodok Vieli, and Cagin Tanir from NetSec group, ETH Zurich for discovering and notifying us about the issue. The CacheFlush type of attacks (NSCacheFlush, CNAMECacheFlush) try to evict cached data by utilizing rogue zones and a steady rogue stream to a resolver. Based on the zone, the stream, the configured cache size and the legitimate traffic, Unbound could experience a degradation of service if a useful entry is evicted and Unbound needs to resolve again. As a mitigation to the NSCacheFlush attack Unbound is setting a limit of 20 RRs in an NS RRset. We would like to thank Yehuda Afek, Anat Bremler-Barr, Shoham Danino and Yuval Shavitt (Tel-Aviv University and Reichman University) for discovering and notifying us about the issue. Other fixes in this release are bug fixes. Also the unbound control commands that flush the cache can clear both the memory and cachedb module cache. The ipset module can use BSD pf tables. The new option `dnstap-sample-rate: 100` can be used to log 1/N messages, for use in high volume server environments where the log server does not keep up. The new DNSSEC key for the root, 38696 from 2024 has been added. It is added to the default root keys in unbound-anchor. The content can be inspected with `unbound-anchor -l`. Older versions of Unbound can keep up with the root key with `auto-trust-anchor-file` that has RFC5011 key rollover. Also unbound-anchor can fetch the keys from the website with a certificate if needed. For cookie secrets, it is possible to perform rollover. The file with cookie secret in use and the staging secret is configured with `cookie-secret-file`. With the remote control the rollover can be performed, add_cookie_secret, activate_cookie_secret, drop_cookie_secret and print_cookie_secrets can be used for that. Compared to the RC1, the release has a fix for module loading on Windows, and a spelling correction. Features - Fix #1071: [FR] Clear both in-memory and cachedb module cache with `unbound-control flush*` commands. - Fix #144: Port ipset to BSD pf tables. - Add dnstap-sample-rate that logs only 1/N messages, for high volume server environments. Thanks Dan Luther. - Add root key 38696 from 2024 for DNSSEC validation. It is added to the default root keys in unbound-anchor. The content can be inspected with `unbound-anchor -l`. - Merge #1090: Cookie secret file. Adds `cookie-secret-file: "unbound_cookiesecrets.txt"` option to store cookie secrets for EDNS COOKIE secret rollover. The remote control add_cookie_secret, activate_cookie_secret and drop_cookie_secret commands can be used for rollover, the command print_cookie_secrets shows the values in use. Bug Fixes - Fix CAMP issues with global quota. Thanks to Huayi Duan, Marco Bearzi, Jodok Vieli, and Cagin Tanir from NetSec group, ETH Zurich. - Fix CacheFlush issues with limit on NS RRs. Thanks to Yehuda Afek, Anat Bremler-Barr, Shoham Danino and Yuval Shavitt (Tel-Aviv University and Reichman University). - Merge #1062: Fix potential overflow bug while parsing port in function cfg_mark_ports. - Fix for #1062: declaration before statement, avoid print of null, and redundant check for array size. - Fix to squelch udp connect errors in the log at low verbosity about invalid argument for IPv6 link local addresses. - Fix when the mesh jostle is exceeded that nameserver targets are marked as resolved, so that the lookup is not stuck on the requestlist. - Add missing common functions to tdir tests. - Merge #1070: Fix rtt assignement for low values of infra-cache-max-rtt. - Merge #1069: Fix unbound-control stdin commands for multi-process Unbounds. - Fix unbound-control commands that read stdin in multi-process operation (local_zones_remove, local_zones, local_datas_remove, local_datas, view_local_datas_remove, view_local_datas).

And it does not remove it twice on a mesh_send_reply call. The reply h2_stream is NULL when not in use, for more initialisation. - Fix dnstap wakeup, a running wakeup timer is left to expire and not increased, a timer is started when the dtio thread is sleeping, the timer set disabled when the dtio thread goes to sleep, and after sleep the thread checks to see if there are messages to log immediately. - Merge #1110: Make fallthrough explicit for libworker.c. - For #1110: Test for fallthrough attribute in configure and add fallthrough attribute annotations. - Fix compile when the compiler does not support the noreturn attribute. - Fix to have empty definition when not supported for weak attribute. - Fix uninitialized variable warning in create_tcp_accept_sock. - Fix link of dnstap without openssl. - Fix link of unbound-dnstap-socket without openssl. - Fix #1106: ratelimit-below-domain logs the wrong FROM address. - Cleanup ede.tdir test. - For #935 and #1104, clarify RPZ order and semantics. - Fix to document parameters of auth_zone_verify_zonemd_with_key. - Fix for #1114: Fix that cache fill for forward-host names is performed, so that with nonzero target-fetch-policy it fetches forwarder addresses and uses them from cache.
