|---|---|---|---|---|---|
| CVE-2019-25032 | 2 Debian, Nlnetlabs | 2 Debian Linux, Unbound | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| Unbound before 1.9.5 allows an integer overflow in the regional allocator via regional_alloc. NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited | |||||
| CVE-2019-18934 | 3 Fedoraproject, Nlnetlabs, Opensuse | 3 Fedora, Unbound, Leap | 2026-06-17 | 6.8 MEDIUM | 7.3 HIGH |
| Unbound 1.6.4 through 1.9.4 contain a vulnerability in the ipsec module that can cause shell code execution after receiving a specially crafted answer. This issue can only be triggered if unbound was compiled with `--enable-ipsecmod` support, and ipsecmod is enabled and used in the configuration. | |||||
| CVE-2019-16866 | 2 Canonical, Nlnetlabs | 2 Ubuntu Linux, Unbound | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| Unbound before 1.9.4 accesses uninitialized memory, which allows remote attackers to trigger a crash via a crafted NOTIFY query. The source IP address of the query must match an access-control rule. | |||||
| CVE-2019-13207 | 1 Nlnetlabs | 1 Name Server Daemon | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| nsd-checkzone in NLnet Labs NSD 4.2.0 has a Stack-based Buffer Overflow in the dname_concatenate() function in dname.c. | |||||
| CVE-2017-15105 | 3 Canonical, Debian, Nlnetlabs | 3 Ubuntu Linux, Debian Linux, Unbound | 2026-06-17 | 5.0 MEDIUM | 5.3 MEDIUM |
| A flaw was found in the way unbound before 1.6.8 validated wildcard-synthesized NSEC records. An improperly validated wildcard NSEC record could be used to prove the non-existence (NXDOMAIN answer) of an existing wildcard record, or trick unbound into accepting a NODATA proof. | |||||
| CVE-2017-1000232 | 1 Nlnetlabs | 1 Ldns | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| A double-free vulnerability in str2host.c in ldns 1.7.0 have unspecified impact and attack vectors. | |||||
| CVE-2017-1000231 | 1 Nlnetlabs | 1 Ldns | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| A double-free vulnerability in parse.c in ldns 1.7.0 have unspecified impact and attack vectors. | |||||
| CVE-2016-6173 | 1 Nlnetlabs | 1 Nsd | 2026-06-17 | 7.8 HIGH | 7.5 HIGH |
| 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 | 3 Canonical, Debian, Nlnetlabs | 3 Ubuntu Linux, Debian Linux, Unbound | 2026-06-17 | 4.3 MEDIUM | 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 | 2026-06-17 | 2.1 LOW | 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-2013-5661 | 4 Isc, Nic, Nlnetlabs and 1 more | 4 Bind, Knot Resolver, Nsd and 1 more | 2026-06-16 | 2.6 LOW | 5.9 MEDIUM |
| Cache Poisoning issue exists in DNS Response Rate Limiting. | |||||
| CVE-2012-2978 | 1 Nlnetlabs | 1 Nsd | 2026-06-16 | 5.0 MEDIUM | N/A |
| 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 | 2026-06-16 | 6.8 MEDIUM | 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 | 2026-06-16 | 4.3 MEDIUM | 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-2010-0969 | 1 Nlnetlabs | 1 Unbound | 2026-06-16 | 5.0 MEDIUM | 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. | |||||
| CVE-2009-4008 | 1 Nlnetlabs | 1 Unbound | 2026-06-16 | 5.0 MEDIUM | 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-2009-3602 | 1 Nlnetlabs | 1 Unbound | 2026-06-16 | 7.5 HIGH | 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 | 2026-06-16 | 5.0 MEDIUM | 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 | 2026-06-16 | 6.4 MEDIUM | 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. | |||||
