malformed DNSSEC keys. A remote attacker could use this flaw to send a
specially crafted DNS query (for example, a query requiring a response
from a zone containing a deliberately malformed key) that would cause
named functioning as a validating resolver to crash. (CVE-2015-5722)

After installing the update, the BIND daemon (named) will be restarted
automatically."
