| CVE-2020-19860 | 1 Nlnetlabs | 1 Ldns | 2026-06-17 | 4.3 MEDIUM | 6.5 MEDIUM |
| When ldns version 1.7.1 verifies a zone file, the ldns_rr_new_frm_str_internal function has a heap out of bounds read vulnerability. An attacker can leak information on the heap by constructing a zone file payload. | |||||
| CVE-2020-17366 | 1 Nlnetlabs | 1 Routinator | 2026-06-17 | 5.8 MEDIUM | 7.4 HIGH |
| An issue was discovered in NLnet Labs Routinator 0.1.0 through 0.7.1. It allows remote attackers to bypass intended access restrictions or to cause a denial of service on dependent routing systems by strategically withholding RPKI Route Origin Authorisation ".roa" files or X509 Certificate Revocation List files from the RPKI relying party's view. | |||||

| CVE-2020-10772 | 2 Nlnetlabs, Redhat | 2 Unbound, Enterprise Linux | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| An incomplete fix for CVE-2020-12662 was shipped for Unbound in Red Hat Enterprise Linux 7, as part of erratum RHSA-2020:2414. Vulnerable versions of Unbound could still amplify an incoming query into a large number of queries directed to a target, even with a lower amplification ratio compared to versions of Unbound that shipped before the mentioned erratum. This issue is about the incomplete fix for CVE-2020-12662, and it does not affect upstream versions of Unbound. | |||||
