{"id":"CVE-2020-15112","details":"In etcd before versions 3.3.23 and 3.4.10, it is possible to have an entry index greater then the number of entries in the ReadAll method in wal/wal.go. This could cause issues when WAL entries are being read during consensus as an arbitrary etcd consensus participant could go down from a runtime panic when reading the entry.","aliases":["BIT-etcd-2020-15106","BIT-etcd-2020-15112","CVE-2020-15106","GHSA-m332-53r6-2w93","GHSA-p4g4-wgrh-qrg2","GO-2020-0005"],"modified":"2026-03-13T22:01:42.579462Z","published":"2020-08-05T20:15:14.553Z","related":["CGA-92v5-v29p-6fhv","GHSA-m332-53r6-2w93","SUSE-SU-2020:3760-1","SUSE-SU-2024:3656-1"],"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L6B6R43Y7M3DCHWK3L3UVGE2K6WWECMP/"},{"type":"ADVISORY","url":"https://github.com/etcd-io/etcd/security/advisories/GHSA-m332-53r6-2w93"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/etcd-io/etcd","events":[{"introduced":"0"},{"fixed":"4873f5516bd98c82dddb81247038337f25abac4e"},{"introduced":"898bd1351fcf6e0ebce8d7c8bbbbf3f3e42aa42c"},{"fixed":"18dfb9cca345bb2b2fbe73d5fc31028c2477bef1"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"3.3.23"},{"introduced":"3.4.0"},{"fixed":"3.4.10"}]}}],"versions":["v3.4.0","v3.4.1","v3.4.2","v3.4.3","v3.4.4","v3.4.5","v3.4.6","v3.4.7","v3.4.8","v3.4.9"],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"32"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-15112.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
