Unbound 1.24.2 Latest
This security release has additional fixes for CVE-2025-11411.
Promiscuous NS RRSets that complement DNS replies in the authority
section can be used to trick resolvers to update their delegation
information for the zone.
The CVE is described here
https://nlnetlabs.nl/downloads/unbound/CVE-2025-11411.txt
Unbound 1.24.1 included a fix that scrubs unsolicited NS RRSets (and
their respective address records) from replies mitigating the possible
poison effect.
Unbound 1.24.2 includes an additional fix that scrubs unsolicited NS
RRSets (and their respective address records) from YXDOMAIN and
non-referral nodata replies as well, mitigating the possible poison
effect.
We would like to thank TaoFei Guo from Peking University, Yang Luo and
JianJun Chen from Tsinghua University for discovering and responsibly
disclosing the partial mitigation of CVE-2025-11411 in Unbound 1.24.1.

Unbound 1.24.0
Unbound 1.24.0
This release features increased defaults, num.valops statistic,
unbound-control cache_lookup, and bug fixes.
The default value increase for num-queries-per-thread is to make
saturation of the task queue more resource intensive and less
practical. Thanks to Shiming Liu, Network and Information Security
Lab, Tsinghua University for the report.
The default value increase for so-sndbuf is to mitigate a cross-layer
issue where the UDP socket send buffers are exhausted waiting for
ARP/NDP resolution. Thanks to Reflyable for the report.
To help the server start more easily, the setsockopt for sndbuf buffer
size prints a warning instead of a failure to start the server if it
can not set the buffer size.
Various cache -slabs options are auto-configured if not specified
in the config file. It uses a power of two close to the number of
threads. When the option is specified in the config file that value
is used instead.
An extra statistic is added to track the number of signature validation
operations by the validator, num.valops.
The unbound-control cache_lookup command prints cache information for
names in the domain given. This prints similar to dump_cache, but only
names under the zone(s) specified. Because of that it locks the caches
for a much shorter time, and this is good for server responsiveness.
The sock-queue-timeout option is adapted to work on FreeBSD as well
as Linux.
Features
Increase default to num-queries-per-thread: 2048, when unbound is
compiled with libevent. It makes saturation of the task queue more
resource intensive and less practical. Thanks to Shiming Liu,
Network and Information Security Lab, Tsinghua University for the
report.
Merge #1276: Auto-configure '-slabs' values.
Change default for so-sndbuf to 1m, to mitigate a cross-layer
issue where the UDP socket send buffers are exhausted waiting

- Merge PR #762: Downstream DNS Server Cookies a la RFC7873 and
RFC9018. Create server cookies for clients that send client cookies.
This needs to be explicitly turned on in the config file with:
`answer-cookie: yes`. A `cookie-secret:` can be configured for
anycast setups. Without one, a random cookie secret is generated.
The acl option `allow_cookie` allows queries with either a valid
cookie or over a stateful transport. The statistics output has
`queries_cookie_valid` and `queries_cookie_client` and
`queries_cookie_invalid` information. The `ip\-ratelimit\-cookie:`
value determines a rate limit for queries with cookies, if desired.
- Fix regional_alloc_init for potential unaligned source of the copy.

- Add testcase for refreshing expired error responses.
9 February 2023: Wouter
- Fix to ignore entirely empty responses, and try at another authority.
This turns completely empty responses, a type of noerror/nodata into
a servfail, but they do not conform to RFC2308, and the retry can
fetch improved content.
- Fix unit tests for spurious empty messages.
- Fix consistency of unit test without roundrobin answers for the
cnametooptout unit test.

- Set max-udp-size default to 1232. This is the same default value as
the default value for edns-buffer-size. It restricts client edns
buffer size choices, and makes unbound behave similar to other DNS
resolvers. The new choice, down from 4096 means it is harder to get
large responses from Unbound. Thanks to Xiang Li, from NISL Lab,
Tsinghua University.
- Add harden-unknown-additional option. It removes
unknown records from the authority section and additional section.
Thanks to Xiang Li, from NISL Lab, Tsinghua University.

not hamper future protocol developments.
- Fix test for new default.
18 January 2023: Wouter
- Fix not following cleared RD flags potentially enables amplification
