How to fix?

Upgrade Wolfi bind to version 9.20.29-r1 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 Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

In a query response, an attacker may send named multiple copies of a record that should only exist once (such as an SOA record). If the RDATA is the same on all the copies, the record is appended to the in-memory RDATA set, which can cause increased memory usage of the negative cache and possibly lead to other memory attack vectors. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1.
