An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-33957 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/notaryproject/notation (Go): affected all versions; fixed in 1.0.0-rc.6\n- github.com/notaryproject/notation (Go): affected all versions; fixed in 1.0.0-rc.6\n- github.com/notaryproject/notation (Go): affected all versions; fixed in 1.0.0-rc.6\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-2023-33957/ (Markdown: https://insights.sbomify.com/CVE-2023-33957/index.md)","id":"CVE-2023-33957","markdown":"https://insights.sbomify.com/CVE-2023-33957/index.md","name":"CVE-2023-33957","record":{"aliases":["GHSA-9m3v-v4r5-ppx7","GO-2023-1829"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OCI artifact signing tool","requires_auth":"high_privilege","summary":"An attacker with registry access can cause denial of service by adding excessive signatures, impacting users running the inspect command.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"notation-go","vendor":"notaryproject"}],"cvss":{"score":2.6,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"notation is a CLI tool to sign and verify OCI artifacts and container images.
