How to fix?

There is no fixed version for Debian:9 adns.

NVD Description

Note: Versions mentioned in the description apply only to the upstream adns package and not the adns package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

An issue was discovered in adns before 1.5.2. It fails to ignore apparent answers before the first RR that was found the first time. when this is fixed, the second answer scan finds the same RRs at the first. Otherwise, adns can be confused by interleaving answers for the CNAME target, with the CNAME itself. In that case the answer data structure (on the heap) can be overrun. With this fixed, it prefers to look only at the answer RRs which come after the CNAME, which is at least arguably correct.
