+
+ A flaw in delegation handling could be exploited to put
+ named into an infinite loop, in which
+ each lookup of a name server triggered additional lookups
+ of more name servers. This has been addressed by placing
+ limits on the number of levels of recursion
+ named will allow (default 7), and
+ on the number of queries that it will send before
+ terminating a recursive query (default 50).
+
+
+ The recursion depth limit is configured via the
+ option, and the query limit
+ via the option.
+
+
+ The flaw was discovered by Florian Maury of ANSSI, and is
+ disclosed in CVE-2014-8500. [RT #37580]

+
+ Two separate problems were identified in BIND's GeoIP code that
+ could lead to an assertion failure. One was triggered by use of
+ both IPv4 and IPv6 address families, the other by referencing
+ a GeoIP database in named.conf which was
+ not installed. Both are covered by CVE-2014-8680. [RT #37672]
+ [RT #37679]
+
+
+ A less serious security flaw was also found in GeoIP: changes
+ to the geoip-directory option in
+ named.conf were ignored when running
+ rndc reconfig. In theory, this could allow
+ named to allow access to unintended clients.
