An update for bind is now available for openEuler-24.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-3329 Final 1.0 1.0 2026-08-13 Initial 2026-08-13 2026-08-13 openEuler SA Tool V1.0 2026-08-13 bind security update An update for bind is now available for openEuler-24.03-LTS-SP3 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 is operating properly. Security Fix(es): A DNSSEC validating resolver that is under a random subdomain attack against a DNSSEC-signed zone can suffer from runaway memory usage. The attacker needs to be able to send queries faster than the resolver can perform validation. The increased memory usage can be orders of magnitude beyond the limit configured in the `max-cache-size` parameter. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.24-S1.(CVE-2026-11622) An update for bind is now available for openEuler-24.03-LTS-SP3. openEuler Security has rated this update as having a security impact of high.
