{"id":"CVE-2024-41434","details":"PingCAP TiDB v8.1.0 was discovered to contain a buffer overflow via the component (*Column).GetDecimal. This allows attackers to cause a Denial of Service (DoS) via a crafted input to the 'RemoveUnnecessaryFirstRow', it will check the expression between 'Agg' and 'GroupBy', but does not check the return type. NOTE: PingCAP disputes this, arguing that reproduction did not cause the security impact of service interruption to other users. They maintain it is a complex query bug in the product but not a DoS.","modified":"2026-08-12T03:51:21.894809784Z","published":"2024-09-03T00:00:00Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/41xxx/CVE-2024-41434.json","cna_assigner":"mitre","isDisputed":true},"references":[{"type":"WEB","url":"https://gist.github.com/ycybfhb/4aa6809695b9e8a1cd1429e597c17517"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/41xxx/CVE-2024-41434.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-41434"},{"type":"REPORT","url":"https://github.com/pingcap/tidb/issues/53733"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pingcap/tidb","events":[{"introduced":"945d07c5d5c7a1ae212f6013adfb187f2de24b23"},{"last_affected":"945d07c5d5c7a1ae212f6013adfb187f2de24b23"}],"database_specific":{"source":"CPE_STRING","cpe":"cpe:2.3:a:pingcap:tidb:8.1.0:-:*:*:*:*:*:*","extracted_events":[{"introduced":"8.1.0-NA"},{"last_affected":"8.1.0-NA"}]}}],"versions":["8.1.0-NA","v8.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-41434.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L"}]}
