Remote code execution via heap buffer overflow
Published Feb 13, 2024 · Updated Aug 10, 2026
Heap-based buffer overflow in Microsoft WDAC OLE DB provider for SQL Server allows remote attackers to execute code after user interaction. Microsoft identifies heap corruption but has not disclosed the malformed input or memory-copy operation that overruns the allocation. Exploitation requires user interaction; successful exploitation runs attacker-controlled code in the affected user's security context.
