It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-8939 in the wild and no public exploit code.\n\nAffected product: Google LLC Asylo. 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-2020-8939/ (Markdown: https://insights.sbomify.com/CVE-2020-8939/index.md)","id":"CVE-2020-8939","markdown":"https://insights.sbomify.com/CVE-2020-8939/index.md","name":"CVE-2020-8939","record":{"aliases":["GHSA-8mgg-4h42-8rj6"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Asylo enclave library","requires_auth":"low_privilege","summary":"An out-of-bounds read in Asylo allows attackers to read memory from the enclave heap via the inet_ntop function.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[{"product":"asylo","vendor":"google"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"An out of bounds read on the enc_untrusted_inet_ntop function allows an attack to extend the result size that is used by memcpy() to read memory from within the enclave heap.
