Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-15106 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2020-15106/ (Markdown: https://insights.sbomify.com/CVE-2020-15106/index.md)","id":"CVE-2020-15106","markdown":"https://insights.sbomify.com/CVE-2020-15106/index.md","name":"CVE-2020-15106","record":{"aliases":["AZL-6388","DEBIAN-CVE-2020-15106","UBUNTU-CVE-2020-15106"],"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":"low_privilege","summary":"An attacker can cause a panic in etcd by forging a large frame size in the WAL file, leading to denial of service for RAFT participants.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"etcd","vendor":"etcd"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"In etcd before versions 3.3.23 and 3.4.10, a large slice causes panic in decodeRecord method.
