| Unbound before 1.9.5 allows an assertion failure and denial of service in synth_cname. 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-2019-25035 | 2 Debian, Nlnetlabs | 2 Debian Linux, Unbound | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| Unbound before 1.9.5 allows an out-of-bounds write in sldns_bget_token_par. 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-2019-25034 | 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 sldns_str2wire_dname_buf_origin, leading to an out-of-bounds write. 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-2019-25033 | 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 the ALIGN_UP macro. 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-2019-25032 | 2 Debian, Nlnetlabs | 2 Debian Linux, Unbound | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |

| 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-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-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-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. | |||||
