Insight
Insight
Change #4777 (introduced in October 2017) introduced an unforeseen issue in releases which were issued after that date, affecting which clients are permitted to make recursive queries to a BIND nameserver. The intended (and documented) behavior is that if an operator has not specified a value for the 'allow-recursion' setting, it SHOULD default to one of the following: none, if 'recursion no, ' is set in named.conf, a value inherited from the 'allow-query-cache' or 'allow-query' settings IF 'recursion yes, ' (the default for that setting) AND match lists are explicitly set for 'allow-query-cache' or 'allow-query' (see the BIND9 Administrative Reference Manual section 6.2 for more details), or the intended default of 'allow-recursion {localhost, localnets, }, ' if 'recursion yes, ' is in effect and no values are explicitly set for 'allow-query-cache' or 'allow-query'. However, because of the regression introduced by change #4777, it is possible when 'recursion yes, ' is in effect and no match list values are provided for 'allow-query-cache' or 'allow-query' for the setting of 'allow-recursion' to inherit a setting of all hosts from the 'allow-query' setting default, improperly permitting recursion to all clients. Affects BIND 9.9.12, 9.10.7, 9.11.3, 9.12.0-9.12.1-P2, the development release 9.13.0, and also releases 9.9.12-S1, 9.10.7-S1, 9.11.3-S1, and 9.11.3-S2 from BIND 9 Supported Preview Edition.(CVE-2018-5738) Controls for zone transfers may not be properly applied to Dynamically Loadable Zones (DLZs) if the zones are writable Versions affected: BIND 9.9.0 - 9.10.8-P1, 9.11.0 - 9.11.5-P2, 9.12.0 - 9.12.3-P2, and versions 9.9.3-S1 - 9.11.5-S3 of BIND 9 Supported Preview Edition. Versions 9.13.0 - 9.13.6 of the 9.13 development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for vulnerability to CVE-2019-6465.(CVE-2019-6465) 'managed-keys' is a feature which allows a BIND resolver to automatically maintain the keys used by trust anchors which operators configure for use in DNSSEC validation. Due to an error in the managed-keys feature it is possible for a BIND server which uses managed-keys to exit due to an assertion failure if, during key rollover, a trust anchor's keys are replaced with keys which use an unsupported algorithm. Versions affected: BIND 9.9.0 - 9.10.8-P1, 9.11.0 - 9.11.5-P1, 9.12.0 - 9.12.3-P1, and versions 9.9.3-S1 - 9.11.5-S3 of BIND 9 Supported Preview Edition. Versions 9.13.0 - 9.13.6 of the 9.13 development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for vulnerability to CVE-2018-5745.(CVE-2018-5745)
