{"id":"CVE-2024-41433","details":"PingCAP TiDB v8.1.0 was discovered to contain a buffer overflow via the component expression.ExplainExpressionList. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted input. NOTE: PingCAP maintains that the actual reproduction of this issue did not cause the security impact of service interruption to other users. They argue that this is a complex query bug and not a DoS vulnerability.","modified":"2026-04-10T05:13:39.778186Z","published":"2024-09-03T21:15:16.050Z","references":[{"type":"ADVISORY","url":"https://gist.github.com/ycybfhb/eec3a1eefe4c85eb22f1bca6114359a1"},{"type":"REPORT","url":"https://github.com/pingcap/tidb/issues/53796"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pingcap/tidb","events":[{"introduced":"0"},{"last_affected":"945d07c5d5c7a1ae212f6013adfb187f2de24b23"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"8.1.0-NA"}]}}],"versions":["Beta20160630","Beta20160730","Pre-GA","beta4","rc1","rc2","rc2-preview","rc3","rc4","v1.0.0","v1.1.0-alpha","v1.1.0-alpha.1","v1.1.0-beta","v2.0.0-rc.1","v2.0.0-rc.3","v2.0.0-rc.4","v2.1.0-alpha","v2.1.0-beta","v2.1.0-rc.1","v2.1.0-rc.2","v2.1.0-rc.3","v3.0.0-beta","v3.0.0-beta.1","v3.0.0-rc.1","v4.0.0-alpha","v4.0.0-beta","v4.0.0-beta.2","v5.1.0-alpha","v5.2.0-alpha","v5.3.0-alpha","v5.4.0-alpha","v5.5.0-alpha","v6.0.0-alpha","v6.1.0-alpha","v6.2.0-alpha","v6.3.0-alpha","v6.4.0-alpha","v6.5.0-alpha","v6.6.0-alpha","v6.7.0-alpha","v7.1.0-alpha","v7.2.0-alpha","v7.3.0-alpha","v7.4.0-alpha","v7.5.0-alpha","v7.6.0-alpha","v8.0.0-alpha","v8.1.0","v8.1.0-alpha"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-41433.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
