CVE-2016-9444 [HIGH] CVE-2016-9444: named in ISC BIND 9 named in ISC BIND 9.x before 9.9.9-P5, 9.10.x before 9.10.4-P5, and 9.11.x before 9.11.0-P2 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted DS resource record in an answer.

CVE-2020-8623 [HIGH] CWE-617 CVE-2020-8623: 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 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 "--enable-native-pkcs11" * be signin

CVE-2023-3341 [HIGH] CVE-2023-3341: The code that processes control channel messages sent to `named` calls certain functions recursively during packet parsing The code that processes control channel messages sent to `named` calls certain functions recursively during packet parsing. Recursion depth is only limited by the maximum accepted packet size; depending on the environment, this may cause the packet-parsing code to run out of available stack memory, causing `named` to terminate unexpectedly

CVE-2017-3143 [MEDIUM] CVE-2017-3143: An attacker who is able to send and receive messages to an authoritative DNS server and who has knowledge of a valid TSIG key name for the zone and se An attacker who is able to send and receive messages to an authoritative DNS server and who has knowledge of a valid TSIG key name for the zone and service being targeted may be able to manipulate BIND into accepting an unauthorized dynamic update. Affects BIND 9.4.0->9.8.8, 9.9.0->9.9.10-P1, 9.10.0->9.10.5-P1

CVE-2016-6170 [MEDIUM] CVE-2016-6170: ISC BIND through 9 ISC BIND through 9.9.9-P1, 9.10.x through 9.10.4-P1, and 9.11.x through 9.11.0b1 allows primary DNS servers to cause a denial of service (secondary DNS server crash) via a large AXFR response, and possibly allows IXFR servers to cause a denial of service (IXFR client crash) via a large IXFR response and allows remote authenticated users to cause a denial of service (primary DNS server crash) via a large UPDATE message.

CVE-2026-1519 [HIGH] bind9 vulnerabilities bind9 vulnerabilities Samy Medjahed discovered that Bind incorrectly handled insecure delegation validation. A remote attacker could possibly use this issue to cause excessive NSEC3 iterations, consuming CPU resources, and leading to a denial of service. (CVE-2026-1519) Vitaly Simonovich discovered that Bind incorrectly handled memory when preparing DNSSEC proofs of non-existence. A remote attacker could possibly use this issue to cause memory consump

CVE-2007-2926 [MEDIUM] CVE-2007-2926: ISC BIND 9 through 9 ISC BIND 9 through 9.5.0a5 uses a weak random number generator during generation of DNS query ids when answering resolver questions or sending NOTIFY messages to slave name servers, which makes it easier for remote attackers to guess the next query id and perform DNS cache poisoning.

CVE-2024-0760 [HIGH] CVE-2024-0760: A malicious client can send many DNS messages over TCP, potentially causing the server to become unstable while the attack is in progress A malicious client can send many DNS messages over TCP, potentially causing the server to become unstable while the attack is in progress. The server may recover after the attack ceases. Use of ACLs will not mitigate the attack. This issue affects BIND 9 versions 9.18.1 through 9.18.27, 9.19.0 through 9.19.24, and 9.18.11-S1

CVE-2018-5743 [HIGH] CVE-2018-5743: By design, BIND is intended to limit the number of TCP clients that can be connected at any given time By design, BIND is intended to limit the number of TCP clients that can be connected at any given time. The number of allowed connections is a tunable parameter which, if unset, defaults to a conservative value for most servers. Unfortunately, the code which was intended to limit the number of simultaneous connections contained an error which could be exploit

CVE-2023-2828 [HIGH] CVE-2023-2828: Every `named` instance configured to run as a recursive resolver maintains a cache database holding the responses to the queries it has recently sent Every `named` instance configured to run as a recursive resolver maintains a cache database holding the responses to the queries it has recently sent to authoritative servers. The size limit for that cache database can be configured using the `max-cache-size` statement in the configuration file; it defaults to 90

CVE-2024-1975 [HIGH] CVE-2024-1975: If a server hosts a zone containing a "KEY" Resource Record, or a resolver DNSSEC-validates a "KEY" Resource Record from a DNSSEC-signed domain in cac If a server hosts a zone containing a "KEY" Resource Record, or a resolver DNSSEC-validates a "KEY" Resource Record from a DNSSEC-signed domain in cache, a client can exhaust resolver CPU resources by sending a stream of SIG(0) signed requests. This issue affects BIND 9 versions 9.0.0 through 9.11.37, 9.16.0 thr

CVE-2015-8000 [MEDIUM] CVE-2015-8000: db db.c in named in ISC BIND 9.x before 9.9.8-P2 and 9.10.x before 9.10.3-P2 allows remote attackers to cause a denial of service (REQUIRE assertion failure and daemon exit) via a malformed class attribute.

CVE-2017-3137 [MEDIUM] bind9 vulnerabilities bind9 vulnerabilities It was discovered that the resolver in Bind made incorrect assumptions about ordering when processing responses containing a CNAME or DNAME. An attacker could use this cause a denial of service. (CVE-2017-3137) Oleg Gorokhov discovered that in some situations, Bind did not properly handle DNS64 queries. An attacker could use this to cause a denial of service. (CVE-2017-3136) Mike Lalumiere discovered that in some situations, B
