"A denial of service flaw was found in the way BIND processed certain
records with malformed class attributes. A remote attacker could use
this flaw to send a query to request a cached record with a malformed
class attribute that would cause named functioning as an authoritative
or recursive server to crash. (CVE-2015-8000)

Note: This issue affects authoritative servers as well as recursive
servers, however authoritative servers are at limited risk if they
perform authentication when making recursive queries to resolve
addresses for servers listed in NS RRSETs.

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