An issue in Technitium DNS Server v.14.3 and before allows a remote attacker to cause a denial of service via the DnsServerApp.exe, DnsServerApp.dll, TechnitiumLibrary.Net/Dns/DnsClient.cs components

Technitium DNS Server aggressively tries to fetch missing RRSIG records or mismatched DNSKEY records. An attacker in control of a domain can cause a vulnerable system to generate excessive network traffic. Fixed in 15.0.

Dual DHCP DNS Server 8.01 improperly accepts and caches UDP DNS responses without validating that the response originates from a legitimate configured upstream DNS server. The implementation matches responses primarily by TXID and inserts results into the cache, enabling a remote attacker to inject forged responses…

Technitium DNS Server before 10.0 allows a self-CNAME denial-of-service attack in which a CNAME loop causes an answer to contain hundreds of records.

An issue was discovered in Technitium DNS Server through 8.0.2 that allows variant V2 of unintended domain name resolution. A revoked domain name can still be resolvable for a long time, including expired domains and taken-down malicious domains. The effects of an exploit would be widespread and highly impactful,…

Improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability in cgi component in Synology DNS Server before 2.2.2-5027 allows remote authenticated users to delete arbitrary files via unspecified vectors.

A vulnerability in the bailiwick checking function in Technitium DNS Server <= v7.0 exists that allows specific malicious users to inject `NS` records of any domain (even TLDs) into the cache and conduct a DNS cache poisoning attack.

An issue was discovered in the trust-dns-server crate before 0.18.1 for Rust. DNS MX and SRV null targets are mishandled, causing stack consumption.

An issue was discovered in Dual DHCP DNS Server 7.40. Due to insufficient access restrictions in the default installation directory, an attacker can elevate privileges by replacing the DualServer.exe binary.

An issue was discovered in Home DNS Server 0.10. Due to insufficient access restrictions in the default installation directory, an attacker can elevate privileges by replacing the HomeDNSServer.exe binary.

In BIND 9.10.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.10.5-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker that can reach a vulnerable system with a specially crafted query packet can trigger a crash. To be vulnerable, the system must: * be running BIND that was built with…

In BIND 9.0.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker on the network path for a TSIG-signed request, or operating the server receiving the TSIG-signed request, could send a truncated response to that request, triggering an…

In BIND 9.14.0 -> 9.16.5, 9.17.0 -> 9.17.3, If a server is configured with both QNAME minimization and 'forward first' then an attacker who can send queries to it may be able to trigger the condition that will cause the server to crash. Servers that 'forward only' are not affected.

Directory traversal vulnerability in the SYNO.DNSServer.Zone.MasterZoneConf in Synology DNS Server before 2.2.1-3042 allows remote authenticated attackers to write arbitrary files via the domain_name parameter.

Buffer overflow in Dual DHCP DNS Server 1.0 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via the DHCP options field.

Multiple implementations of the DNS protocol, including (1) Poslib 1.0.2-1 and earlier as used by Posadis, (2) Axis Network products before firmware 3.13, and (3) Men & Mice Suite 2.2x before 2.2.3 and 3.5.x before 3.5.2, allow remote attackers to cause a denial of service (CPU and network bandwidth consumption) by…
