NVD Description

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

iterator.c in NLnet Labs Unbound before 1.5.1 does not limit delegation chaining, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a large or infinite number of referrals.

Remediation

Upgrade Debian:10 unbound to version 1.4.22-3 or higher.
