Description

A flaw was found in the way BIND handled requests for TKEY DNS resource records. A remote attacker could use this flaw to make named (functioning as an authoritative DNS server or a DNS resolver) exit unexpectedly with an assertion failure via a specially crafted DNS request packet. (CVE-2015-5477)

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