Fixes

Solution

Upgrade to the patched release most closely related to your current version of BIND. These can all be downloaded from http://www.isc.org/downloads. BIND 9 version 9.9.9-P6 BIND 9 version 9.10.4-P6 BIND 9 version 9.11.0-P3 BIND Supported Preview Edition is a special feature preview branch of BIND provided to eligible ISC support customers. BIND 9 version 9.9.9-S8


Workaround

While it is possible to avoid the condition by removing either DNS64 or RPZ from the configuration, or by carefully restricting the contents of the policy zone, for an affected configuration the most practical and safest course of action is to upgrade to a version of BIND without this vulnerability.
