CVE-2017-3136: An error handling synthesized records could cause an assertion failure when using DNS64 with "break-dnssec yes;"

First published: Sun Mar 12 2017(Updated: )

A query with a specific set of characteristics could cause a server using DNS64 to encounter an assertion failure and terminate. An attacker could deliberately construct a query, enabling denial-of-service against a server if it was configured to use the DNS64 feature and other preconditions were met. Servers are at risk if they are configured to use DNS64 and if the option "break-dnssec yes;" is in use. External References: <a href="https://kb.isc.org/article/AA-01465">https://kb.isc.org/article/AA-01465</a> Mitigation: Servers which have configurations which require DNS64 and "break-dnssec yes;" should upgrade. Servers which are not using these features in conjunction are not at risk from this defect.
