CVE-2026-39155 1 Knot-dns 1 Knot Dns 2026-07-24 N/A
Knot DNS before 3.4.10 and 3.5.x before 3.5.4 contains a vulnerability in mod-onlinesign where the next NSEC owner name can be computed incorrectly. This can create an overly broad authenticated denial interval, allowing downstream validating resolvers using aggressive negative caching to synthesize negative answers for legitimate names and causing resolver-side denial of service.
CVE-2016-6171 1 Knot-dns 1 Knot Dns 2025-04-20 8.6 High
Knot DNS before 2.3.0 allows remote DNS servers to cause a denial of service (memory exhaustion and slave server crash) via a large zone transfer for (1) DDNS, (2) AXFR, or (3) IXFR.
CVE-2017-11104 2 Debian, Knot-dns 2 Debian Linux, Knot Dns 2025-04-20 5.9 Medium
Knot DNS before 2.4.5 and 2.5.x before 2.5.2 contains a flaw within the TSIG protocol implementation that would allow an attacker with a valid key name and algorithm to bypass TSIG authentication if no additional ACL restrictions are set, because of an improper TSIG validity period check.
