Technitium DNS Server

An issue in Technitium DNS Server v.13.5 allows a remote attacker to cause a denial of service via the rate-limiting component

Technitium 11.5.3 allows remote attackers to cause a denial of service (bandwidth amplification) because the DNSBomb manipulation causes accumulation of low-rate DNS queries such that there is a large-sized response in a burst of traffic.

An issue was discovered in Technitium through 11.0.2. It enables attackers to launch amplification attacks (3 times more than other "golden model" software like BIND) and cause potential DoS.

An issue was discovered in Technitium through 11.0.2. The forwarding mode enables attackers to create a query loop using Technitium resolvers, launching amplification attacks and causing potential DoS.

An issue was discovered in Technitium 11.0.2. There is a vulnerability (called BadDNS) in DNS resolving software, which triggers a resolver to ignore valid responses, thus causing DoS (denial of service) for normal resolution. The effects of an exploit would be widespread and highly impactful, because the attacker could just forge a response targeting the source port of a vulnerable resolver without the need to guess the correct TXID.

An issue in Technitium through v13.2.2 enables attackers to conduct a DNS cache poisoning attack and inject fake responses by reviving the birthday attack.

An issue was discovered in Technitium through 11.0.3. It enables attackers to conduct a DNS cache poisoning attack and inject fake responses within 1 second, which is impactful.

Technitium DNS Server before 15.0 allows DNS traffic amplification via cyclic name server delegation.

Denial of service in DNS-over-QUIC in Technitium DNS Server <= v13.2.2 allows remote attackers to permanently stop the server from accepting new DNS-over-QUIC connections by triggering unhandled exceptions in listener threads.
