* Wed Feb 14 2024 Reinhard Max <max@suse.com>
- update to 2.90:
* CVE-2023-50387, CVE-2023-50868, bsc#1219823, bsc#1219826:
Denial Of Service while trying to validate specially crafted
DNSSEC responses
* CVE-2023-49441, bsc#1226091: integer overflow via forward_query
* Fix reversion in --rev-server introduced in 2.88 which caused
breakage if the prefix length is not exactly divisible by 8
(IPv4) or 4 (IPv6).
* Fix possible SEGV when there server(s) for a particular domain
are configured, but no server which is not qualified for a
particular domain.
* Set the default maximum DNS UDP packet sice to 1232.
Obsoletes: dnsmasq-CVE-2023-28450.patch
* Add --no-dhcpv4-interface and --no-dhcpv6-interface for better
control over which inetrfaces are providing DHCP service.
* Fix issue with stale caching
* Add configurable caching for arbitrary RR-types.
* Add --filter-rr option, to filter arbitrary RR-types.
* Fri Oct 13 2023 Thorsten Kukuk <kukuk@suse.com>
- SLP got dropped, remove config (bsc#1214884)
* Sat May 13 2023 Callum Farmer <gmbr3@opensuse.org>
- Correct rundir from /var/run to /run for pid file
* Tue Apr 25 2023 Reinhard Max <max@suse.com>
- bsc#1209358, CVE-2023-28450, dnsmasq-CVE-2023-28450.patch:
default maximum EDNS.0 UDP packet size should be 1232
* Mon Feb 06 2023 Paolo Stivanin <info@paolostivanin.com>
- update to 2.89:
* Fix bug introduced in 2.88 (commit fe91134b) which can result
in corruption of the DNS cache internal data structures and
logging of "cache internal error". This has only been seen
in one place in the wild, and it took considerable effort
to even generate a test case to reproduce it, but there's
no way to be sure it won't strike, and the effect is to break
the cache badly. Installations with DNSSEC enabled are more
likely to see the problem, but not running DNSSEC does not
guarantee that it won't happen. Thanks to Timo van Roermund
for reporting the bug and for his great efforts in chasing
it down. (boo#1207174)
- remove no longer needed rpmlintrc filters
* Fri Dec 23 2022 Dirk Müller <dmueller@suse.com>
- update to 2.88:
* Fix bug in --dynamic-host when an interface has /16 IPv4
* address.
* Add --fast-dns-retry option. This gives dnsmasq the ability
to originate retries for upstream DNS queries itself, rather
than relying on the downstream client. This is most useful
when doing DNSSEC over unreliable upstream networks. It comes
with some cost in memory usage and network bandwidth.
* Add --use-stale-cache option. When set, if a DNS name exists
in the cache, but its time-to-live has expired, dnsmasq will
return the data anyway.
* handle removal of whole files or entries within files.
* Wed Oct 26 2022 Dirk Müller <dmueller@suse.com>
- update to 2.87 (bsc#1197872, CVE-2022-0934):
* Allow arbitrary prefix lengths in --rev-server and
- -domain=....,local
* Replace --address=/#/..... functionality which got
missed in the 2.86 domain search rewrite.
* Add --nftset option, like --ipset but for the newer nftables.
* Add --filter-A and --filter-AAAA options, to remove IPv4 or IPv6
addresses from DNS answers.
* Fix crash doing netbooting when --port is set to zero
to disable the DNS server. Thanks to Drexl Johannes
for the bug report.
* Generalise --dhcp-relay. Sending via broadcast/multicast is
now supported for both IPv4 and IPv6 and the configuration
syntax made easier (but backwards compatible).
* Add snooping of IPv6 prefix-delegations to the DHCP-relay system.
* Finesse parsing of --dhcp-remoteid and --dhcp-subscrid. To be treated
as hex, the pattern must consist of only hex digits AND contain
at least one ':'. Thanks to Bengt-Erik Sandstrom who tripped
over a pattern consisting of a decimal number which was interpreted
surprisingly.
* Include client address in TFTP file-not-found error reports.
Thanks to Stefan Rink for the initial patch, which has been
re-worked by me (srk). All bugs mine.
* Note in manpage the change in behaviour of -address. This behaviour
actually changed in v2.86, but was undocumented there. From 2.86 on,
(eg) --address=/example.com/1.2.3.4 ONLY applies to A queries. All other
types of query will be sent upstream. Pre 2.86, that would catch the
whole example.com domain and queries for other types would get
a local NODATA answer. The pre-2.86 behaviour is still available,
by configuring --address=/example.com/1.2.3.4 --local=/example.com/
* Fix problem with binding DHCP sockets to an individual interface.
Despite the fact that the system call tales the interface _name_ as
a parameter, it actually, binds the socket to interface _index_.
Deleting the interface and creating a new one with the same name
leaves the socket bound to the old index. (Creating new sockets
always allocates a fresh index, they are not reused). We now
take this behaviour into account and keep up with changing indexes.
* Add --conf-script configuration option.
* Enhance --domain to accept, for instance,
- -domain=net2.thekelleys.org.uk,eth2 so that hosts get a domain
which relects the interface they are attached to in a way which
doesn't require hard-coding addresses. Thanks to Sten Spans for
the idea.
* Fix write-after-free error in DHCPv6 server code.
CVE-2022-0934 refers.
* Add the ability to specify destination port in
DHCP-relay mode. This change also removes a previous bug
where --dhcp-alternate-port would affect the port used
to relay _to_ as well as the port being listened on.
The new feature allows configuration to provide bug-for-bug
compatibility, if required. Thanks to Damian Kaczkowski
for the feature suggestion.
* Bound the value of UDP packet size in the EDNS0 header of
forwarded queries to the configured or default value of
edns-packet-max. There's no point letting a client set a larger
value if we're unable to return the answer. Thanks to Bertie
Taylor for pointing out the problem and supplying the patch.

network part from the network of a local interface. Useful
for routers with dynamically prefixes.

- Update to 2.83:
* bsc#1177077: Fixed DNSpooq vulnerabilities
* Use the values of --min-port and --max-port in outgoing
TCP connections to upstream DNS servers.
* Fix a remote buffer overflow problem in the DNSSEC code.
Any dnsmasq with DNSSEC compiled in and enabled is vulnerable
to this, referenced by CVE-2020-25681, CVE-2020-25682,
CVE-2020-25683 CVE-2020-25687.
* Be sure to only accept UDP DNS query replies at the address
from which the query was originated. This keeps as much
entropy in the {query-ID, random-port} tuple as possible, to
help defeat cache poisoning attacks. Refer: CVE-2020-25684.
* Use the SHA-256 hash function to verify that DNS answers
received are for the questions originally asked. This replaces
the slightly insecure SHA-1 (when compiled with DNSSEC) or
the very insecure CRC32 (otherwise). Refer: CVE-2020-25685
* Handle multiple identical near simultaneous DNS queries better.
Previously, such queries would all be forwarded independently.
This is, in theory, inefficent but in practise not a problem,
_except_ that is means that an answer for any of the forwarded
queries will be accepted and cached.
An attacker can send a query multiple times, and for each
repeat, another {port, ID} becomes capable of accepting the
answer he is sending in the blind, to random IDs and ports.
The chance of a succesful attack is therefore multiplied by the
number of repeats of the query. The new behaviour detects
repeated queries and merely stores the clients sending repeats
so that when the first query completes, the answer can be sent
to all the clients who asked. Refer: CVE-2020-25686.
