How to fix?

Upgrade Alpine:3.23 dnsdist to version 2.0.4-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream dnsdist package and not the dnsdist package as distributed by Alpine. See How to fix? for Alpine:3.23 relevant fixed versions and status.

An attacker might be able to trigger an out-of-bounds read by sending a crafted DNS response packet, when custom Lua code uses newDNSPacketOverlay to parse DNS packets. The out-of-bounds read might trigger a crash, leading to a denial of service, or access unrelated memory, leading to potential information disclosure.
