A programming error in the nxdomain-redirect feature can cause an assertion
failure in query.c if the alternate namespace used by nxdomain-redirect is
a descendant of a zone that is served locally. The most likely scenario
where this might occur is if the server, in addition to performing NXDOMAIN
redirection for recursive clients, is also serving a local copy of the root
zone or using mirroring to provide the root zone, although other
configurations are also possible. Versions affected: BIND 9.12.0-> 9.12.4,
9.14.0. Also affects all releases in the 9.13 development branch.
