07 Remediation

Future maintenance releases of BIND will correct the regression which introduced this issue but ISC does not believe that replacement security releases of BIND are required, given that several easy, safe, and completely effective configuration workarounds are available for any operators with affected configurations. However, an advance version of the patch diff which will be applied to future versions is available upon request to security-officer@isc.org and a correction for the behavior in question will debut in the release candidates for BIND 9.9.13, BIND 9.10.8, BIND 9.11.4, and BIND 9.12.2.
