ISC reports:
BIND 9 nameservers using the DNS64 IPv6 transition mechanism are
vulnerable to a software defect that allows a crafted query to
crash the server with a REQUIRE assertion failure. Remote
exploitation of this defect can be achieved without extensive
effort, resulting in a denial-of-service (DoS) vector against
affected servers.
