NVD Description

Note: Versions mentioned in the description apply to the upstream unbound package. See Remediation section below for Debian:10 relevant versions.

Unbound before 1.4.13p2 attempts to free unallocated memory during processing of duplicate CNAME records in a signed zone, which allows remote DNS servers to cause a denial of service (daemon crash) via a crafted response.

Remediation

Upgrade Debian:10 unbound to version 1.4.14-1 or higher.
