An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-9gp7-6833-wv89 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- go.etcd.io/etcd/client/v3 (Go): affected all versions; fixed in 3.3.23\n- go.etcd.io/etcd/client/v3 (Go): affected all versions; fixed in 3.3.23\n- go.etcd.io/etcd/client/v3 (Go): affected from 3.4.0; fixed in 3.4.10\n- go.etcd.io/etcd/client/v3 (Go): affected from 3.4.0; fixed in 3.4.10\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/GHSA-9gp7-6833-wv89/ (Markdown: https://insights.sbomify.com/GHSA-9gp7-6833-wv89/index.md)","id":"GHSA-9gp7-6833-wv89","markdown":"https://insights.sbomify.com/GHSA-9gp7-6833-wv89/index.md","name":"GHSA-9gp7-6833-wv89","record":{"aliases":[],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"etcd distributed key-value store","requires_auth":"none","summary":"An attacker can cause a denial of service in etcd by providing a negative cluster size during service discovery, leading to a panic.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Vulnerability type\nData Validation\n\n### Detail\nWhen an etcd instance attempts to perform service discovery, if a cluster size is provided as a negative value, the etcd instance will panic without recovery.\n\n### References\nFind out more on this vulnerability in the [security audit report](https://github.com/etcd-io/etcd/blob/master/security/SECURITY_AUDIT.pdf)\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Contact the [etcd security committee](https://github.com/etcd-io/etcd/blob/master/security/security-release-process.md#product-security-committee-psc)","ecosystems":["Go"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"etcd having a negative value for cluster node size results in an index out-of-bound panic during service discovery","id":"GHSA-9gp7-6833-wv89","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":4,"n_references":null,"packages":[{"ecosystem":"Go","fixed":["3.3.23"],"introduced":["0"],"last_affected":[],"package":"go.etcd.io/etcd/client/v3","purl":null,"source":"GHSA-9gp7-6833-wv89"},{"ecosystem":"Go","fixed":["3.3.23"],"introduced":["0"],"last_affected":[],"package":"go.etcd.io/etcd/client/v3","purl":"pkg:golang/go.etcd.io/etcd/client/v3","source":"GHSA-9gp7-6833-wv89"},{"ecosystem":"Go","fixed":["3.4.10"],"introduced":["3.4.0"],"last_affected":[],"package":"go.etcd.io/etcd/client/v3","purl":null,"source":"GHSA-9gp7-6833-wv89"},{"ecosystem":"Go","fixed":["3.4.10"],"introduced":["3.4.0"],"last_affected":[],"package":"go.etcd.io/etcd/client/v3","purl":"pkg:golang/go.etcd.io/etcd/client/v3","source":"GHSA-9gp7-6833-wv89"}],"products":null,"published":"2022-10-06","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"An attacker can cause a denial of service in etcd by providing a negative cluster size during service discovery, leading to a panic.","url":"https://insights.sbomify.com/GHSA-9gp7-6833-wv89/"}
