How to fix?

Upgrade Alpine:3.21 bind to version 9.18.41-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:3.21 relevant fixed versions and status.

In specific circumstances, due to a weakness in the Pseudo Random Number Generator (PRNG) that is used, it is possible for an attacker to predict the source port and query ID that BIND will use. This issue affects BIND 9 versions 9.16.0 through 9.16.50, 9.18.0 through 9.18.39, 9.20.0 through 9.20.13, 9.21.0 through 9.21.12, 9.16.8-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.39-S1, and 9.20.9-S1 through 9.20.13-S1.
