UBUNTU-CVE-2026-44690

In NLnet Labs Unbound 1.7.0 up to and including 1.25.1, insufficient validation of the RRSIG.Labels field combined with premature cache writes during RFC 8198 aggressive NSEC processing leads to cache poisoning that permits a malicious actor controlling a single delegated zone to poison arbitrary...

CVE-2026-13321

The CVE relates to BIND DNSSEC validation: the resolver accepts validly-signed NSEC records whose Next Domain Name points outside the signer's zone, enabling potential DNSSEC validation bypass. Affected are BIND 9 releases across multiple series: 9.11.0–9.18.50, 9.20.0–9.20.24, 9.21.0–9.21.23, an...

CVE-2026-13204

If a provably insecure domain is covered by both an NSEC and NSEC3 record at the parent, and there exist an RRSIG for only one of these types, then BIND may exit unexpectedly with an assertion while validating this proof. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through...

CVE-2026-13204

CVE-2026-13204 affects BIND 9 up to 9.18.50, 9.20.24, 9.21.23 and related S1 variants. If a provably insecure domain is covered by both NSEC and NSEC3 at the parent and an RRSIG exists for only one type, BIND may exit unexpectedly with an assertion during proof validation. Mitigation is to upgrad...

unbound: Unbound: Cache poisoning via insufficient RRSIG.Labels validation and premature cache writes

A flaw was found in Unbound. Insufficient validation of the RRSIG.Labels field, combined with premature cache writes during RFC 8198 aggressive NSEC processing, can lead to cache poisoning. This vulnerability allows a malicious actor, controlling a single delegated zone, to poison arbitrary sibli...

CVE-2026-11605 Unnecessary validation of DNSSEC signed records

The issue is a resource exhaustion vulnerability associated with DNSSEC validation. BIND always validates all RRSIG records in an answer, even if they are not strictly needed. A query to an authoritative server/zone which returns many valid but superfluous RRSIG records causes the validator to...

CVE-2026-56416 Possible heap buffer overflow when validator canonicalizes RDATA that contains domain name

In NLnet Labs Unbound up to and including version 1.25.1, when the validator builds the canonical RDATA form for an RRSIG-covered PX/RP/MINFO/SOA RRset, it computes the address of the second embedded domain name as 'datstart + dnamevaliddatstart, ...' and passes it straight to 'querydnametolower'...

CVE-2026-54478

In NLnet Labs Unbound 1.18.0 up to and including 1.25.1, when Unbound listens on a 'proxy-protocol-port' interface with 'answer-cookie: yes', the RFC 9018 server-cookie SipHash is computed over the proxy's wire address instead of the PROXYv2-declared client. One server cookie obtained through a...

CVE-2026-50045 'max-global-quota' reset by DNSSEC validation restarts

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...

CVE-2026-46582

Affected software/versions: NLnet Labs Unbound 1.6.0 up to and including 1.25.1. Issue: a replay of a wildcard RRset as another piece of data can be momentarily treated as DNSSEC secure based on RRSIG validation and cached, then misvalidated on the serve-expired path due to later NSEC validation,...

CVE-2026-46582 A wildcard replay, as another piece of data, triggers poisoning in the serve expired reply path

In NLnet Labs Unbound 1.6.0 up to and including 1.25.1, a replay of a wildcard rrset as another piece of data, could be briefly considered DNSSEC secure based only on the RRSIG validation and stored into cache, before later validation treats it as bogus based on NSEC validation. When the resolvin...
