How to fix?

Upgrade Alpine:3.11 bind to version 9.14.7-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream bind package and not the bind package as distributed by Alpine. See How to fix? for Alpine:3.11 relevant fixed versions and status.

A defect in code added to support QNAME minimization can cause named to exit with an assertion failure if a forwarder returns a referral rather than resolving the query. This affects BIND versions 9.14.0 up to 9.14.6, and 9.15.0 up to 9.15.4.
