Security Fixes

    A race condition could trigger an assertion failure when a large number of incoming packets were being rejected. This flaw is disclosed in CVE-2019-6471. [GL #942]

Bug Fixes

    When qname-minimization was set to relaxed, some improperly configured domains would fail to resolve, but would have succeeded if minimization were disabled. named will now fall back to normal resolution in such cases, and also uses type A rather than NS for minimal queries in order to reduce the likelihood of encountering the problem. [GL #1055]
