NVD Description

Note: Versions mentioned in the description apply only to the upstream bind9 package and not the bind9 package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

ISC BIND 9.x before 9.9.9-P2, 9.10.x before 9.10.4-P2, and 9.11.x before 9.11.0b2, when lwresd or the named lwres option is enabled, allows remote attackers to cause a denial of service (daemon crash) via a long request that uses the lightweight resolver protocol.
