| Package | Affected versions | Patched versions |
|---|---|---|
| unbound | ≥ 1.22.0, < 1.25.2 | 1.25.2 |
In NLnet Labs Unbound 1.22.0 up to and including 1.25.1, a single client query for a deeply nested name under a DNSSEC-signed parent can cause Unbound to send more upstream packets per client query than the configured 'max-global-quota'. This effectively bypasses a security configuration that limits upstream amplification traffic.
