03 Oct 2024 — NLnet Labs Unbound up to and including version 1.21.0 contains a vulnerability when handling replies with very large RRsets that it needs to perform name compression for. Malicious upstreams responses with very large RRsets can cause Unbound to spend a considerable time applying name compression to downstream replies. This can lead to degraded performance and eventually denial of service in well orchestrated attacks. The vulnerability can be exploited by a malicious actor querying Unbound for the specially ... • https://www.nlnetlabs.nl/downloads/unbound/CVE-2024-8508.txt • CWE-606: Unchecked Input for Loop Condition •
CVSS: 7.8EPSS: 4%CPEs: 21EXPL: 3CVE-2023-50387 – bind9: KeyTrap - Extreme CPU consumption in DNSSEC validator
https://notcve.org/view.php?id=CVE-2023-50387
13 Feb 2024 — Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records. Ciertos aspectos DNSSEC del protocolo DNS (en RFC 4035 y RFC relacionados) permiten a ataca... • https://github.com/knqyf263/CVE-2023-50387 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2022-3204
26 Sep 2022 — A vulnerability named 'Non-Responsive Delegation Attack' (NRDelegation Attack) has been discovered in various DNS resolving software. The NRDelegation Attack works by having a malicious delegation with a considerable number of non responsive nameservers. The attack starts by querying a resolver for a record that relies on those unresponsive nameservers. The attack can cause a resolver to spend a lot of time/resources resolving records under a malicious delegation point where a considerable number of unrespo... • https://lists.debian.org/debian-lts-announce/2023/03/msg00024.html • CWE-400: Uncontrolled Resource Consumption •
CVSS: 6.8EPSS: 0%CPEs: 3EXPL: 0CVE-2022-30699 – Novel "ghost domain names" attack by updating almost expired delegation information
https://notcve.org/view.php?id=CVE-2022-30699
01 Aug 2022 — NLnet Labs Unbound, up to and including version 1.16.1, is vulnerable to a novel type of the "ghost domain names" attack. The vulnerability works by targeting an Unbound instance. Unbound is queried for a rogue domain name when the cached delegation information is about to expire. The rogue nameserver delays the response so that the cached delegation information is expired. Upon receiving the delayed answer containing the delegation information, Unbound overwrites the now expired entries. • https://lists.debian.org/debian-lts-announce/2023/03/msg00024.html • CWE-613: Insufficient Session Expiration •

01 Aug 2022 — NLnet Labs Unbound, up to and including version 1.16.1 is vulnerable to a novel type of the "ghost domain names" attack. The vulnerability works by targeting an Unbound instance. Unbound is queried for a subdomain of a rogue domain name. The rogue nameserver returns delegation information for the subdomain that updates Unbound's delegation cache. This action can be repeated before expiry of the delegation information by querying Unbound for a second level subdomain which the rogue nameserver provides new de... • https://lists.debian.org/debian-lts-announce/2023/03/msg00024.html • CWE-613: Insufficient Session Expiration •
