Vulnerability from fkie_nvd - Published: 2024-09-03 20:15 - Updated: 2025-09-04 18:48
Severity ?
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L
Summary
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.
