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.
