Summary

Microsoft SQL Server from 14.0.0 before 14.0.2140.2 (2017 GDR), from 14.0.3006.16 before 14.0.3560.2 (2017 CU31), from 15.0.0 before 15.0.2200.2 (2019 GDR), from 15.0.4003.23 before 15.0.4500.2 (2019 CU32), from 16.0.0 before 16.0.1210.3 (2022 GDR), from 16.0.4003.1 before 16.0.4305.5 (2022 CU27), from 17.0.4006.2 before 17.0.5015.4 (2025 CU9), and from 17.0.1050.2 before 17.0.1145.4 (2025 GDR) are affected. A heap-based buffer overflow (CWE-122) lets code run over the network. An authorized attacker can execute code remotely, and the attack is hard to carry out.
