An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-10063 in the wild and no public exploit code.\n\nAffected product: Zephyrproject Zephyr. 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-2020-10063/ (Markdown: https://insights.sbomify.com/CVE-2020-10063/index.md)","id":"CVE-2020-10063","markdown":"https://insights.sbomify.com/CVE-2020-10063/index.md","name":"CVE-2020-10063","record":{"aliases":["GHSA-x97p-2r85-4gq4"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Zephyr RTOS","requires_auth":"none","summary":"Remote attackers can cause denial of service in Zephyr RTOS by sending malicious CoAP packets that trigger an integer overflow during option parsing.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zephyr","cpe":[{"product":"zephyr","vendor":"zephyrproject"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"A remote adversary with the ability to send arbitrary CoAP packets to be parsed by Zephyr is able to cause a denial of service.
