	--- 9.18.7 released ---

5962.	[security]	Fix memory leak in EdDSA verify processing.
			(CVE-2022-38178) [GL #3487]

5960.	[security]	Fix serve-stale crash that could happen when
			stale-answer-client-timeout was set to 0 and there was

			(CVE-2022-3080) [GL #3517]

5959.	[security]	Fix memory leaks in the DH code when using OpenSSL 3.0.0
			and later versions. The openssldh_compare(),
			openssldh_paramcompare(), and openssldh_todns()
			functions were affected. (CVE-2022-2906) [GL #3491]

5958.	[security]	When an HTTP connection was reused to get
			statistics from the stats channel, and zlib
			compression was in use, each successive
			response sent larger and larger blocks of memory,
			potentially reading past the end of the allocated
			buffer. (CVE-2022-2881) [GL #3493]

5957.	[security]	Prevent excessive resource use while processing large
			delegations. (CVE-2022-2795) [GL #3394]

5956.	[func]		Make RRL code treat all QNAMEs that are subject to
			wildcard processing within a given zone as the same
			name. [GL #3459]

5955.	[port]		The libxml2 library has deprecated the usage of
			xmlInitThreads() and xmlCleanupThreads() functions. Use
			xmlInitParser() and xmlCleanupParser() instead.
			[GL #3518]

5954.	[func]		Fallback to IDNA2003 processing in dig when IDNA2008
			conversion fails. [GL #3485]

5953.	[bug]		Fix a crash on shutdown in delete_trace_entry(). Add
			mctx attach/detach pair to make sure that the memory
			context used by a memory pool is not destroyed before
			the memory pool itself. [GL #3515]

5952.	[bug]		Use quotes around address strings in YAML output.
			[GL #3511]

5951.	[bug]		In some cases, the dnstap query_message field was
			erroneously set when logging response messages.
			[GL #3501]

5948.	[bug]		Fix nsec3.c:dns_nsec3_activex() function, add a missing
			dns_db_detachnode() call. [GL #3500]

5947.	[func]		Change dnssec-policy to allow graceful transition from
			an NSEC only zone to NSEC3. [GL #3486]

5946.	[bug]		Fix statistics channel's handling of multiple HTTP
			requests in a single connection which have non-empty
			request bodies. [GL #3463]

5945.	[bug]		If parsing /etc/bind.key failed, delv could assert
			when trying to parse the built in trust anchors as
			the parser hadn't been reset. [GL !6468]

5944.	[bug]		Fix +http-plain-get and +http-plain-post options
			support in dig. Thanks to Marco Davids at SIDN for
			reporting the problem. [GL !6672]

5942.	[bug]		Fix tkey.c:buildquery() function's error handling by
			adding the missing cleanup code. [GL #3492]

5941.	[func]		Zones with dnssec-policy now require dynamic DNS or
			inline-siging to be configured explicitly. [GL #3381]

5938.	[bug]		An integer type overflow could cause an assertion
			failure when freeing memory. [GL #3483]

5936.	[bug]		Don't enable serve-stale for lookups that error because
			it is a duplicate query or a query that would be
			dropped. [GL #2982]

5935.	[bug]		Fix DiG lookup reference counting bug, which could
			be observed in NSSEARCH mode. [GL #3478]
