NVD Description

Note: Versions mentioned in the description apply only to the upstream bind-pkcs11-libs package and not the bind-pkcs11-libs package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

While backporting a feature for a newer branch of BIND9, RedHat introduced a path leading to an assertion failure in buffer.c:420. Affects RedHat versions bind-9.9.4-65.el7 -> bind-9.9.4-72.el7. No ISC releases are affected. Other packages from other distributions who made the same error may also be affected.
