| CVE-2025-11411 | 1 Nlnetlabs | 1 Unbound | 2025-10-23 | 6.9 Medium |
| NLnet Labs Unbound up to and including version 1.24.0 is vulnerable to possible domain hijack attacks. Promiscuous NS RRSets that complement positive DNS replies in the authority section can be used to trick resolvers to update their delegation information for the zone. Usually these RRSets are used to update the resolver's knowledge of the zone's name servers. A malicious actor can exploit the possible poisonous effect by injecting NS RRSets (and possibly their respective address records) in a reply. This could be done for example by trying to spoof a packet or fragmentation attacks. Unbound would then proceed to update the NS RRSet data it already has since the new data has enough trust for it, i.e., in-zone data for the delegation point. Unbound 1.24.1 includes a fix that scrubs unsolicited NS RRSets (and their respective address records) from replies mitigating the possible poison effect. | ||||
| CVE-2023-39916 | 1 Nlnetlabs | 1 Routinator | 2025-10-03 | 9.3 Critical |
| NLnet Labs’ Routinator 0.9.0 up to and including 0.12.1 as well as 0.14.0 up to and including 0.14.2 contains a possible path traversal vulnerability in the optional, off-by-default keep-rrdp-responses feature that allows users to store the content of responses received for RRDP requests. The location of these stored responses is constructed from the URL of the request. Due to insufficient sanitation of the URL, it is possible for an attacker to craft a URL that results in the response being stored outside of the directory specified for it. | ||||
| CVE-2025-0638 | 1 Nlnetlabs | 1 Routinator | 2025-07-21 | 7.5 High |
| The initial code parsing the manifest did not check the content of the file names yet later code assumed that it was checked and panicked when encountering illegal characters, resulting in a crash of Routinator. | ||||
| CVE-2023-50387 | 8 Fedoraproject, Isc, Microsoft and 5 more | 18 Fedora, Bind, Windows Server 2008 and 15 more | 2025-05-12 | 7.5 High |
| Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records. | ||||
| CVE-2022-3204 | 3 Fedoraproject, Nlnetlabs, Redhat | 4 Fedora, Unbound, Enterprise Linux and 1 more | 2025-05-05 | 7.5 High |
| A vulnerability named 'Non-Responsive Delegation Attack' (NRDelegation Attack) has been discovered in various DNS resolving software. The NRDelegation Attack works by having a malicious delegation with a considerable number of non responsive nameservers. The attack starts by querying a resolver for a record that relies on those unresponsive nameservers. The attack can cause a resolver to spend a lot of time/resources resolving records under a malicious delegation point where a considerable number of unresponsive NS records reside. It can trigger high CPU usage in some resolver implementations that continually look in the cache for resolved NS records in that delegation. This can lead to degraded performance and eventually denial of service in orchestrated attacks. Unbound does not suffer from high CPU usage, but resources are still needed for resolving the malicious delegation. Unbound will keep trying to resolve the record until hard limits are reached. Based on the nature of the attack and the replies, different limits could be reached. From version 1.16.3 on, Unbound introduces fixes for better performance when under load, by cutting opportunistic queries for nameserver discovery and DNSKEY prefetching and limiting the number of times a delegation point can issue a cache lookup for missing records. | ||||

| CVE-2016-6173 | 1 Nlnetlabs | 1 Nsd | 2025-04-20 | N/A |
| NSD before 4.1.11 allows remote DNS master servers to cause a denial of service (/tmp disk consumption and slave server crash) via a zone transfer with unlimited data. | ||||
| CVE-2014-8602 | 4 Canonical, Debian, Nlnetlabs and 1 more | 4 Ubuntu Linux, Debian Linux, Unbound and 1 more | 2025-04-12 | N/A |
| 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. | ||||
| CVE-2014-3209 | 1 Nlnetlabs | 1 Ldns | 2025-04-12 | N/A |
| The ldns-keygen tool in ldns 1.6.x uses the current umask to set the privileges of the private key, which might allow local users to obtain the private key by reading the file. | ||||
| CVE-2009-4008 | 1 Nlnetlabs | 1 Unbound | 2025-04-11 | N/A |
| Unbound before 1.4.4 does not send responses for signed zones after mishandling an unspecified query, which allows remote attackers to cause a denial of service (DNSSEC outage) via a crafted query. | ||||
| CVE-2010-0969 | 1 Nlnetlabs | 1 Unbound | 2025-04-11 | N/A |
| Unbound before 1.4.3 does not properly align structures on 64-bit platforms, which allows remote attackers to cause a denial of service (daemon crash) via unspecified vectors. | ||||

| query.c in NSD 3.0.x through 3.0.8, 3.1.x through 3.1.1, and 3.2.x before 3.2.12 allows remote attackers to cause a denial of service (NULL pointer dereference and child process crash) via a crafted DNS packet. | ||||
| CVE-2011-3581 | 1 Nlnetlabs | 1 Ldns | 2025-04-11 | N/A |
| Heap-based buffer overflow in the ldns_rr_new_frm_str_internal function in ldns before 1.6.11 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a Resource Record (RR) with an unknown type containing input that is longer than a specified length. | ||||
| CVE-2011-1922 | 1 Nlnetlabs | 1 Unbound | 2025-04-11 | N/A |
| daemon/worker.c in Unbound 1.x before 1.4.10, when debugging functionality and the interface-automatic option are enabled, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted DNS request that triggers improper error handling. | ||||
| CVE-2009-3602 | 1 Nlnetlabs | 1 Unbound | 2025-04-09 | N/A |
| Unbound before 1.3.4 does not properly verify signatures for NSEC3 records, which allows remote attackers to cause secure delegations to be downgraded via DNS spoofing or other DNS-related attacks in conjunction with crafted delegation responses. | ||||
| CVE-2009-1755 | 1 Nlnetlabs | 1 Nsd | 2025-04-09 | N/A |
| Off-by-one error in the packet_read_query_section function in packet.c in nsd 3.2.1, and process_query_section in query.c in nsd 2.3.7, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors that trigger a buffer overflow. | ||||
| CVE-2009-1086 | 1 Nlnetlabs | 1 Ldns | 2025-04-09 | N/A |
| Heap-based buffer overflow in the ldns_rr_new_frm_str_internal function in ldns 1.4.x allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code via a DNS resource record (RR) with a long (1) class field (clas variable) and possibly (2) TTL field. | ||||
| CVE-2023-0158 | 1 Nlnetlabs | 1 Krill | 2025-04-04 | 7.5 High |
| NLnet Labs Krill supports direct access to the RRDP repository content through its built-in web server at the "/rrdp" endpoint. Prior to 0.12.1 a direct query for any existing directory under "/rrdp/", rather than an RRDP file such as "/rrdp/notification.xml" as would be expected, causes Krill to crash. If the built-in "/rrdp" endpoint is exposed directly to the internet, then malicious remote parties can cause the publication server to crash. The repository content is not affected by this, but the availability of the server and repository can cause issues if this attack is persistent and is not mitigated. | ||||
| CVE-2024-1622 | 2 Fedoraproject, Nlnetlabs | 2 Fedora, Routinator | 2025-02-27 | 7.5 High |
| Due to a mistake in error checking, Routinator will terminate when an incoming RTR connection is reset by the peer too quickly after opening. | ||||
