| CVE-2026-18664 | 심각9.1 | When ranges are used for access control (i.e. of the form 1.2.3.4-1.2.3.25), because NSD wrongly compares the IP address with the range on little endian systems, IPs that were meant to be allowed may be denied, and, IPs that were meant to be denied access could be allowed. An IPv4 address is compared with IPv4 ranges a | 26/08/2026 |
| CVE-2026-12490 | 높음7.5 | When a provide-xfr is given with a tls-auth-name, a secondary requesting a transfer should provide a client certificate with that name. However, no client certificate is needed when the request comes in over TLS over the regular tls-port (and not the tls-auth-port) or over over TCP over the regular port, when the other | 25/06/2026 |
| CVE-2026-12246 | 높음8.1 | NSD version 4.14.0 introduced a bug where a specially crafted APL RR, with an adflength larger than permitted for the address family will overwrite the stack when the zone is written to disk, with a maximum of 111 attacker controlled bytes. | 25/06/2026 |
| CVE-2026-12245 | 높음7.5 | NSD from version 4.13.0 has a heap use-after-free bug in logging errors on TLS connections, causing a crash of the server process, which can be triggered trivially by sending a DNS query over a DoT connection, and closing the connection without reading the response. | 25/06/2026 |
| CVE-2026-12244 | 높음8.8 | If NSD is configured as secondary for a zone, the primary of that zone can crash NSD with an AXFR containing a DNS message with a special crafted SVCB RR with an rdata size of 65512, that let's an (uint16_t) variable that is used to allocate space needed for the RR wrap (because total size > 65535), causing a heap over | 25/06/2026 |
| CVE-2013-5661 | 보통5.9 | Cache Poisoning issue exists in DNS Response Rate Limiting. | 05/11/2019 |
| CVE-2016-6173 | 높음7.5 | 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. | 09/02/2017 |

| CVE-2009-1755 | 보통5.0 | 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. | 22/05/2009 |
