| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2026-49943 | CZ.NIC BIRD Internet Routing Daemon through 2.19.0 contains a stack-based buffer overflow in the BGP AS_PATH mask matching implementation in nest/a-path.c. The as_path_match() function uses a fixed-size stack array of 2048 + 1 pm_pos entries, while parse_path() expands AS_PATH segments from a received BGP UPDATE without enforcing a corresponding capacity limit. When RFC 8654 BGP Extended Messages are enabled and a BIRD filter evaluates an AS path mask expression such as "bgp_path ~ [= ... =]", a | [email protected] | 6.3 | 0.30% | 2026-06-02 | 2026-06-17 |
| CVE-2023-50387 | 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. | [email protected] | 7.5 | 100.00% | 2024-02-14 | 2026-06-17 |
| CVE-2023-46317 | Knot Resolver before 5.7.0 performs many TCP reconnections upon receiving certain nonsensical responses from servers. | [email protected] | 7.5 | 0.64% | 2023-10-22 | 2026-06-17 |
| CVE-2023-26249 | Knot Resolver before 5.6.0 enables attackers to consume its resources, launching amplification attacks and potentially causing a denial of service. Specifically, a single client query may lead to a hundred TCP connection attempts if a DNS server closes connections without providing a response. | [email protected] | 7.5 | 0.71% | 2023-02-20 | 2026-06-17 |
| CVE-2022-40188 | Knot Resolver before 5.5.3 allows remote attackers to cause a denial of service (CPU consumption) because of algorithmic complexity. During an attack, an authoritative server must return large NS sets or address sets. | [email protected] | 7.5 | 1.45% | 2022-09-23 | 2026-06-17 |
| CVE-2022-32983 | Knot Resolver through 5.5.1 may allow DNS cache poisoning when there is an attempt to limit forwarding actions by filters. | [email protected] | 5.3 | 0.76% | 2022-06-20 | 2026-06-17 |
| CVE-2021-40083 | Knot Resolver before 5.3.2 is prone to an assertion failure, triggerable by a remote attacker in an edge case (NSEC3 with too many iterations used for a positive wildcard proof). | [email protected] | 7.5 | 1.38% | 2021-08-24 | 2026-06-17 |
| CVE-2021-26928 | BIRD through 2.0.7 does not provide functionality for password authentication of BGP peers. Because of this, products that use BIRD (which may, for example, include Tigera products in some configurations, as well as products of other vendors) may have been susceptible to route redirection for Denial of Service and/or Information Disclosure. NOTE: a researcher has asserted that the behavior is within Tigera’s area of responsibility; however, Tigera disagrees | [email protected] | 6.8 | 1.01% | 2021-06-04 | 2026-06-16 |
| CVE-2018-1110 | A flaw was found in knot-resolver before version 2.3.0. Malformed DNS messages may cause denial of service. | [email protected] | 7.5 | 1.11% | 2021-03-29 | 2026-06-16 |
| CVE-2021-3346 | Foris before 101.1.1, as used in Turris OS, lacks certain HTML escaping in the login template. | [email protected] | 9.8 | 1.59% | 2021-01-29 | 2026-06-17 |
| CVE-2020-12667 | Knot Resolver before 5.1.1 allows traffic amplification via a crafted DNS answer from an attacker-controlled server, aka an "NXNSAttack" issue. This is triggered by random subdomains in the NSDNAME in NS records. | [email protected] | 7.5 | 2.62% | 2020-05-19 | 2026-06-16 |
| CVE-2019-19331 | knot-resolver before version 4.3.0 is vulnerable to denial of service through high CPU utilization. DNS replies with very many resource records might be processed very inefficiently, in extreme cases taking even several CPU seconds for each such uncached message. For example, a few thousand A records can be squashed into one DNS message (limit is 64kB). | [email protected] | 7.5 | 2.17% | 2019-12-16 | 2026-06-16 |
| CVE-2013-5661 | Cache Poisoning issue exists in DNS Response Rate Limiting. | [email protected] | 5.9 | 3.45% | 2019-11-05 | 2026-06-16 |
| CVE-2019-16159 | BIRD Internet Routing Daemon 1.6.x through 1.6.7 and 2.x through 2.0.5 has a stack-based buffer overflow. The BGP daemon's support for RFC 8203 administrative shutdown communication messages included an incorrect logical expression when checking the validity of an input message. Sending a shutdown communication with a sufficient message length causes a four-byte overflow to occur while processing the message, where two of the overflow bytes are attacker-controlled and two are fixed. | [email protected] | 7.5 | 3.15% | 2019-09-09 | 2026-06-16 |
| CVE-2019-10191 | A vulnerability was discovered in DNS resolver of knot resolver before version 4.1.0 which allows remote attackers to downgrade DNSSEC-secure domains to DNSSEC-insecure state, opening possibility of domain hijack using attacks against insecure DNS protocol. | [email protected] | 7.5 | 1.93% | 2019-07-16 | 2026-06-16 |
| CVE-2019-10190 | A vulnerability was discovered in DNS resolver component of knot resolver through version 3.2.0 before 4.1.0 which allows remote attackers to bypass DNSSEC validation for non-existence answer. NXDOMAIN answer would get passed through to the client even if its DNSSEC validation failed, instead of sending a SERVFAIL packet. Caching is not affected by this particular bug but see CVE-2019-10191. | [email protected] | 7.5 | 1.99% | 2019-07-16 | 2026-06-16 |
| CVE-2018-10920 | Improper input validation bug in DNS resolver component of Knot Resolver before 2.4.1 allows remote attacker to poison cache. | [email protected] | 6.8 | 3.24% | 2018-08-02 | 2026-06-16 |
| CVE-2014-0486 | Knot DNS before 1.5.2 allows remote attackers to cause a denial of service (application crash) via a crafted DNS message. | [email protected] | 7.5 | 3.46% | 2018-03-27 | 2026-06-16 |
| CVE-2018-1000002 | Improper input validation bugs in DNSSEC validators components in Knot Resolver (prior version 1.5.2) allow attacker in man-in-the-middle position to deny existence of some data in DNS via packet replay. | [email protected] | 3.7 | 1.09% | 2018-01-22 | 2026-06-16 |
