An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-8619 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2020-8619/ (Markdown: https://insights.sbomify.com/CVE-2020-8619/index.md)","id":"CVE-2020-8619","markdown":"https://insights.sbomify.com/CVE-2020-8619/index.md","name":"CVE-2020-8619","record":{"aliases":["ALPINE-CVE-2020-8619","DEBIAN-CVE-2020-8619","GHSA-fw3j-5rrr-7j3r","UBUNTU-CVE-2020-8619"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"DNS server software","requires_auth":"high_privilege","summary":"An attacker with high privileges can cause a denial of service in ISC BIND9 by introducing specific zone records that trigger an assertion failure.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"isc","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"bind","vendor":"isc"},{"product":"steelstore_cloud_integrated_storage","vendor":"netapp"},{"product":"leap","vendor":"opensuse"}],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-404","name":"Improper Resource Shutdown or Release"}],"description":"In ISC BIND9 versions BIND 9.11.14 -\u003e 9.11.19, BIND 9.14.9 -\u003e 9.14.12, BIND 9.16.0 -\u003e 9.16.3, BIND Supported Preview Edition 9.11.14-S1 -\u003e 9.11.19-S1: Unless a nameserver is providing authoritative service for one or more zones and at least one zone contains an empty non-terminal entry containing an asterisk (\"*\") character, this defect cannot be encountered.
