+
+5481.	[security]	"update-policy" rules of type "subdomain" were
+			incorrectly treated as "zonesub" rules, which allowed
+			keys used in "subdomain" rules to update names outside
+			of the specified subdomains. The problem was fixed by
+			making sure "subdomain" rules are again processed as
+			described in the ARM. (CVE-2020-8624) [GL #2055]

-Subject: [PATCH] Fix GeoIP2 memory leak upon reconfiguration
-
-Loaded GeoIP2 databases are only released when named is shut down, but
-not during server reconfiguration.  This causes memory to be leaked
-every time "rndc reconfig" or "rndc reload" is used, as long as any
-GeoIP2 database is in use.  Fix by releasing any loaded GeoIP2 databases
-before reloading them.  Do not call dns_geoip_shutdown() until server
-shutdown as that function releases the memory context used for caching
-GeoIP2 lookup results.
-
-(cherry picked from commit 670afbe84a87e202fa795079d9d6d1639bcf391d)
-(cherry picked from commit 95a5589fa2ac3956fecfef780158a2745718c860)

-Subject: [PATCH] Change the invalid CIDR from parser error to warning
-
-In [RT #43367], the BIND 9 changed the strictness of address / prefix
-length checks:
-
-    Check prefixes in acls to make sure the address and
-    prefix lengths are consistent.  Warn only in
-    BIND 9.11 and earlier.
-
-Unfortunately, a regression slipped in and the check was made an error
-also in the BIND 9.11.  This commit fixes the regression, but turning
-the error into a warning.
