Description Arvid Requate

Upstream Debian package version 1:9.8.4.dfsg.P1-6+nmu2+deb7u12 fixes this issue:

* ISC BIND 9.1.0 through 9.8.4-P2 and 9.9.0 through 9.9.2-P2 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via malformed options data in an OPT resource record. (CVE-2016-2848)
