If control channel input is accepted from the network (limited to localhost by default), an unauthenticated attacker could cause named to crash. (CVE-2016-1285)

An error when parsing signature records for DNAME records having specific properties can lead to named exiting due to an assertion failure in resolver.c or db.c. An attacker able to cause a server to make a query deliberately chosen to generate a malicious response can cause named to stop execution with an assertion failure, resulting in denial of service to clients.
