Fix remote buffer overflow CERT VU#434904

The problem is in the sort_rrset() function and allows a remote
attacker to overwrite memory. Any dnsmasq instance with DNSSEC
enabled is vulnerable.

-version 2.90
-	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. Thanks to Daniel Danzberger for
-	spotting this bug.
-
-	Set the default maximum DNS UDP packet sice to 1232. This
-	has been the recommended value since 2020 because it's the
-	largest value that avoid fragmentation, and fragmentation
-	is just not reliable on the modern internet, especially
-	for IPv6. It's still possible to override this with
-	--edns-packet-max for special circumstances.
-
-	Add --no-dhcpv4-interface and --no-dhcpv6-interface for
-	better control over which inetrfaces are providing DHCP service.
-
-	Fix issue with stale caching: After replying with stale data,
-	dnsmasq sends the query upstream to refresh the cache asynchronously
-	and sometimes sends the wrong packet: packet length can be wrong,
-	and if an EDE marking stale data is added to the answer that can
-	end up in the query also. This bug only seems to cause problems
-	when the usptream server is a DOH/DOT proxy. Thanks to Justin He
-	for the bug report.
-	
-	
-version 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.
-
-
-version 2.88
-	Fix bug in --dynamic-host when an interface has /16 IPv4
-  	address. Thanks to Mark Dietzer for spotting this.
-
-	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. (It attempts to refresh the
-	data with an upstream query after returning the stale data.)
-	This can improve speed and reliability. It comes
-	at the expense of sometimes returning out-of-date data and
-	less efficient cache utilisation, since old data cannot be
-	flushed when its TTL expires, so the cache becomes
-	strictly least-recently-used.
-
-	Add --port-limit option which allows tuning for robustness in
-	the face of some upstream network errors. Thanks to
-	Prashant Kumar Singh, Ravi Nagayach and Mike Danilov,
-	all of Amazon Web Services, for their efforts in developing this
-	and the stale-cache and fast-retry options.
-
-	Make --hostsdir (but NOT --dhcp-hostsdir and --dhcp-optsdir)
-	handle removal of whole files or entries within files.
-	Thanks to Dominik Derigs for the initial patches for this.
-
-	Fix bug, introduced in 2.87, which could result in DNS
-	servers being removed from the configuration when reloading
-	server configuration from DBus, or re-reading /etc/resolv.conf
-	Only servers from the same source should be replaced, but some
-	servers from other sources (i.e., hard coded or another dynamic source)
-	could mysteriously disappear. Thanks to all reporting this,
-	but especially Christopher J. Madsen who reduced the problem
-	to an easily reproducible case which saved much labour in
-	finding it.
-
-	Add --no-round-robin option.
-
-	Allow domain names as well as IP addresses when specifying
-	upstream DNS servers. There are some gotchas associated with this
-	(it will mysteriously fail to work if the dnsmasq instance
-	being started is in the path from the system resolver to the DNS),
-	and a seemingly sensible configuration like
-	--server=domain.name@1.2.3.4 is unactionable if domain.name
-	only resolves to an IPv6 address). There are, however,
-	cases where is can be useful. Thanks to Dominik Derigs for
-	the patch.
-
-	Handle DS records for unsupported crypto algorithms correctly.
-	Such a DS, as long as it is validated, should allow answers
-	in the domain it attests to be returned as unvalidated, and not
-	as a validation error.
-
-	Optimise reading large numbers of --server options. When re-reading
-	upstream servers from /etc/resolv.conf or other sources that
-	can change dnsmasq tries to avoid memory fragmentation by re-using
-	existing records that are being re-read unchanged. This involves
-	seaching all the server records for each new one installed.
-	During startup this search is pointless, and can cause long
-	start times with thousands of --server options because the work
-	needed is O(n^2). Handle this case more intelligently.
-	Thanks to Ye Zhou for spotting the problem and an initial patch.
-	
-	If we detect that a DNS reply from upstream is malformed don't
-	return it to the requestor; send a SEVFAIL rcode instead.
-
-	
-version 2.87
-        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.
-	Thanks to Chen Zhenge for the patch.
-	
-	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.
-	
-	Fix problem with the configuration
-	
-	--server=/some.domain/# --address=/#/<ip> --server=<server_ip>
-
-	This would return <ip> for queries in some.domain, rather than
-	forwarding the query via the default server.
-
-	Tweak DHCPv6 relay code so that packets relayed towards a server
-	have source address on the server-facing network, not the
-	client facing network. Thanks to Luis Thomas for spotting this
-	and initial patch.
-
-
-version 2.86
-	Handle DHCPREBIND requests in the DHCPv6 server code.
-	Thanks to Aichun Li for spotting this omission, and the initial
-	patch.
-
-	Fix bug which caused dnsmasq to lose track of processes forked
-	to handle TCP DNS connections under heavy load. The code
-	checked that at least one free process table slot was
-	available before listening on TCP sockets, but didn't take
-	into account that more than one TCP connection could
-	arrive, so that check was not sufficient to ensure that
-	there would be slots for all new processes. It compounded
-	this error by silently failing to store the process when
-	it did run out of slots. Even when this bug is triggered,
-	all the right things happen, and answers are still returned.
-	Only under very exceptional circumstances, does the bug
-	manifest itself: see
-	https://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2021q2/014976.html
-	Thanks to Tijs Van Buggenhout for finding the conditions under
-	which the bug manifests itself, and then working out
-	exactly what was going on.
-
-	Major rewrite of the DNS server and domain handling code.
-	This should be largely transparent, but it drastically
-	improves performance and reduces memory foot-print when
-	configuring large numbers domains of the form
-	local=/adserver.com/
-	or
-	local=/adserver.com/#
-	Lookup times now grow as log-to-base-2 of the number of domains,
-	rather than greater than linearly, as before.
-	The change makes multiple addresses associated with a domain work
-	address=/example.com/1.2.3.4
-	address=/example.com/5.6.7.8
-	It also handles multiple upstream servers for a domain better; using
-	the same try/retry algorithms as non domain-specific servers. This
-	also applies to DNSSEC-generated queries.
-	Finally, some of the oldest and gnarliest code in dnsmasq has had
-	a significant clean-up. It's far from perfect, but it _is_ better.
-
-	Revise resource handling for number of concurrent DNS queries. This
-	used to have a global limit, but that has a problem when using
-	different servers for different upstream domains. Queries which are
-	routed by domain to an upstream server which is not responding will
-	build up and trigger the limit, which breaks DNS service for
-	all other domains which could be handled by other servers. The
-	change is to make the limit per server-group, where a server group
-	is the set of servers configured for a particular domain. In the
-	common case, where only default servers are declared, there is
-	no effective change.
-
-	Improve efficiency of DNSSEC. The sharing point for DNSSEC RR data
-	used to be when it entered the cache, having been validated. After
-	that queries requiring the KEY or DS records would share the cached
-	values. There is a common case in dual-stack hosts that queries for
-	A and AAAA records for the same domain are made simultaneously.
-	If required keys were not in the cache, this would result in two
-	requests being sent upstream for the same key data (and all the
-	subsequent chain-of-trust queries.) Now we combine these requests
-	and elide the duplicates, resulting in fewer queries upstream
-	and better performance. To keep a better handle on what's
-	going on, the "extra" logging mode has been modified to associate
-	queries and answers  for DNSSEC queries in the same way as ordinary
-	queries. The requesting address and port have been removed from
-	DNSSEC logging lines, since this is no longer strictly defined.
-
-	Connection track mark based DNS query filtering. Thanks to
-	Etan Kissling for implementing this It extends query filtering
-	support beyond what is currently possible
-	with the `--ipset` configuration option, by adding support for:
-	1) Specifying allowlists on a per-client basis, based on their
-	   associated Linux connection track mark.
-	2) Dynamic configuration of allowlists via Ubus.
-	3) Reporting when a DNS query resolves or is rejected via Ubus.
-	4) DNS name patterns containing wildcards.
-	Disallowed queries are not forwarded; they are rejected
-	with a REFUSED error code.
-
-	Allow smaller than 64 prefix lengths in synth-domain, with caveats.
-	--synth-domain=1234:4567::/56,example.com is now valid.
-
-	Make domains generated by --synth-domain appear in replies
-	when in authoritative mode.
-
-	Ensure CAP_NET_ADMIN capability is available when
-	conntrack is configured. Thanks to Yick Xie for spotting
-	the lack of this.
-
-	When --dhcp-hostsfile --dhcp-optsfile and --addn-hosts are
-	given a directory as argument, define the order in which
-	files within that directory are read (alphabetical order
-	of filename). Thanks to Ed Wildgoose for the initial patch
-	and motivation for this.
-
-	Allow adding IP address to nftables set in addition to
-	ipset.
-
-	
-version 2.85
-        Fix problem with DNS retries in 2.83/2.84.
-        The new logic in 2.83/2.84 which merges distinct requests
-	for the same domain causes problems with clients which do
-	retries as distinct requests (differing IDs and/or source ports.)
-	The retries just get piggy-backed on the first, failed, request.
-        The logic is now changed so that distinct requests for repeated
-        queries still get merged into a single ID/source port, but
-	they now always trigger a re-try upstream.
-        Thanks to Nicholas Mu for his analysis.
-
-	Tweak sort order of tags in get-version. v2.84 sorts
-	before v2.83, but v2.83 sorts before v2.83rc1 and 2.83rc1
-	sorts before v2.83test1. This fixes the problem which lead
-	to 2.84 announcing itself as 2.84rc2.
-
- 	Avoid treating a --dhcp-host which has an IPv6 address
-	as eligible for use with DHCPv4 on the grounds that it has
-	no address, and vice-versa. Thanks to Viktor Papp for
-	spotting the problem. (This bug was fixed was back in 2.67, and
-	then regressed in 2.81).
-
-	Add --dynamic-host option: A and AAAA records which take their
-	network part from the network of a local interface. Useful
-	for routers with dynamically prefixes. Thanks
-	to Fred F for the suggestion.
-
-	Teach --bogus-nxdomain and --ignore-address to take an IPv4 subnet.
-
-	Use random source ports where possible if source
-	addresses/interfaces in use.
-	CVE-2021-3448 applies. Thanks to Petr Menšík for spotting this.
-	It's possible to specify the source address or interface to be
-	used when contacting upstream name servers: server=8.8.8.8@1.2.3.4
-	or server=8.8.8.8@1.2.3.4#66 or server=8.8.8.8@eth0, and all of
-	these have, until now, used a single socket, bound to a fixed
-	port. This was originally done to allow an error (non-existent
-	interface, or non-local address) to be detected at start-up. This
-	means that any upstream servers specified in such a way don't use
-	random source ports, and are more susceptible to cache-poisoning
-	attacks.
-	We now use random ports where possible, even when the
-	source is specified, so server=8.8.8.8@1.2.3.4 or
-	server=8.8.8.8@eth0 will use random source
-	ports. server=8.8.8.8@1.2.3.4#66 or any use of --query-port will
-	use the explicitly configured port, and should only be done with
-	understanding of the security implications.
-	Note that this change changes non-existing interface, or non-local
-	source address errors from fatal to run-time. The error will be
-	logged and communication with the server not possible.
-
-	Change the method of allocation of random source ports for DNS.
-	Previously, without min-port or max-port configured, dnsmasq would
-	default to the compiled in defaults for those, which are 1024 and
-	65535. Now, when neither are configured, it defaults instead to
-	the kernel's ephemeral port range, which is typically
-	32768 to 60999 on Linux systems. This change eliminates the
-	possibility that dnsmasq may be using a registered port > 1024
-	when a long-running daemon starts up and wishes to claim it.
-	This change does likely slightly reduce the number of random ports
-	and therefore the protection from reply spoofing. The older
-	behaviour can be restored using the min-port and max-port config
-	switches should that be a concern.
-
-	Scale the size of the DNS random-port pool based on the
-	value of the --dns-forward-max configuration.
-
-	Tweak TFTP code to check sender of all received packets, as
-	specified in RFC 1350 para 4.
-
-	Support some wildcard matching of input tags to --tag-if.
-	Thanks to Geoff Back for the idea and the patch.
-
-	
-version 2.84
-	Fix a problem, introduced in 2.83, which could see DNS replies
-	being sent via the wrong socket. On machines running both
-	IPv4 and IPv6 this could result in sporadic messages of
-	the form "failed to send packet: Network is unreachable" and
-	the lost of the query. Since the error is sporadic and of
-	low probability, the client retry would normally succeed.
-
-	Change HAVE_NETTLEHASH compile-time to HAVE_CRYPTOHASH.
-
-
 version 2.83
-	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, inefficient 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
-	successful 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.

+Summary: A lightweight caching nameserver
+
+%description
+Dnsmasq is lightweight, easy to configure DNS forwarder and DHCP server. It 
+is designed to provide DNS and, optionally, DHCP, to a small network. It can
+serve the names of local machines which are not in the global DNS. The DHCP 
+server integrates with the DNS server and allows machines with DHCP-allocated
+addresses to appear in the DNS with names configured either in each host or 
+in a central configuration file. Dnsmasq supports static and dynamic DHCP 
+leases and BOOTP for network booting of diskless machines.
