More information:

Tony Finch and Marco Davids reported an assertion failure in BIND, a DNS server implementation, which causes the server process to terminate. This denial-of-service vulnerability is related to a defect in the processing of responses with DNAME records from authoritative servers and primarily affects recursive resolvers.

For the stable distribution (jessie), this problem has been fixed in version 1:9.9.5.dfsg-9+deb8u8.

We recommend that you upgrade your bind9 packages.
