An incomplete fix for CVE-2020-12662 was shipped for Unbound in Red Hat
Enterprise Linux 7, as part of erratum RHSA-2020:2414. Vulnerable versions
of Unbound could still amplify an incoming query into a large number of
queries directed to a target, even with a lower amplification ratio
compared to versions of Unbound that shipped before the mentioned erratum.
This issue is about the incomplete fix for CVE-2020-12662, and it does not
affect upstream versions of Unbound.
