A flaw in the way named processes these records may trigger an attempt to add the same RRset to the ANSWER section more than once. This causes an assertion check in BIND to fail.  DNAME records are processed by both authoritative and recursive servers. For authoritative servers, the DNAME record triggering the flaw can be retrieved from a zone database. For servers performing recursion, such a record is processed in the course of a query sent to an authoritative server.  Affects BIND 9.0.0 -\u003e 9.11.29, 9.12.0 -\u003e 9.16.13, and versions BIND 9.9.3-S1 -\u003e 9.11.29-S1 and 9.16.8-S1 -\u003e 9.16.13-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -\u003e 9.17.11 of the BIND 9.17 development branch.",
