EUVD-2026-31110

Undefined behavior may result due to a race condition leading to a use-after-free violation. If BIND receives an incoming DNS message signed with SIG0, it begins work to validate that signature. If, during that validation, the "recursive-clients" limit is reached as would occur during a query...

OESA-2026-2058 bind security update

BIND Berkeley Internet Name Domain is an implementation of the DNS Domain Name System protocols. BIND includes a DNS server named, which resolves host names to IP addresses; a resolver library routines for applications to use when interfacing with DNS; and tools for verifying that the DNS server ...

SUSE CVE-2026-3591

A use-after-return vulnerability exists in the named server when handling DNS queries signed with SIG0. Using a specially-crafted DNS request, an attacker may be able to cause an ACL to improperly mismatch an IP address. In a default-allow ACL denying only specific IP addresses, this may lead to...

CVE-2025-13878

Malformed BRID/HHIT records can cause named to terminate unexpectedly. This issue affects BIND 9 versions 9.18.40 through 9.18.43, 9.20.13 through 9.20.17, 9.21.12 through 9.21.16, 9.18.40-S1 through 9.18.43-S1, and 9.20.13-S1 through 9.20.17-S1...

SUSE CVE-2025-40777

If a named caching resolver is configured with serve-stale-enable yes, and with stale-answer-client-timeout set to 0 the only allowable value other than disabled, and if the resolver, in the process of resolving a query, encounters a CNAME chain involving a specific combination of cached or...

Astra Linux - уязвимость в bind9

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...

UBUNTU-CVE-2024-11187

It is possible to construct a zone such that some queries to it will generate responses containing numerous records in the Additional section. An attacker sending many such queries can cause either the authoritative server itself or an independent resolver to use disproportionate resources...

UBUNTU-CVE-2024-4076

Client queries that trigger serving stale data and that also require lookups in local authoritative zone data may result in an assertion failure. This issue affects BIND 9 versions 9.16.13 through 9.16.50, 9.18.0 through 9.18.27, 9.19.0 through 9.19.24, 9.11.33-S1 through 9.11.37-S1, 9.16.13-S1...

CVE-2023-2829 Malformed NSEC records can cause named to terminate unexpectedly when synth-from-dnssec is enabled

A named instance configured to run as a DNSSEC-validating recursive resolver with the Aggressive Use of DNSSEC-Validated Cache RFC 8198 option synth-from-dnssec enabled can be remotely terminated using a zone with a malformed NSEC record. This issue affects BIND 9 versions 9.16.8-S1 through...

To be vulnerable, the system must: be running BIND tha...

SUSE CVE-2021-25219

In BIND 9.3.0 - 9.11.35, 9.12.0 - 9.16.21, and versions 9.9.3-S1 - 9.11.35-S1 and 9.16.8-S1 - 9.16.21-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 - 9.17.18 of the BIND 9.17 development branch, exploitation of broken authoritative servers using a flaw in response...

CVE-2022-3094 An UPDATE message flood may cause named to exhaust all available memory

Sending a flood of dynamic DNS updates may cause named to allocate large amounts of memory. This, in turn, may cause named to exit due to a lack of free memory. We are not aware of any cases where this has been exploited. Memory is allocated prior to the checking of access permissions ACLs and is...
