There is no fixed version for Debian:10 unbound.
NVD Description
Note: Versions mentioned in the description apply only to the upstream unbound package and not the unbound package as distributed by Debian.
See How to fix? for Debian:10 relevant fixed versions and status.
Unbound before 1.9.5 allows an integer overflow in sldns_str2wire_dname_buf_origin, leading to an out-of-bounds write. NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited
