Remote code execution via heap-based buffer overflow
Published Sep 8, 2026 · Updated Sep 9, 2026
A heap-based buffer overflow in Microsoft Windows Imaging Component allows remote attackers to execute code through crafted image data. Microsoft identifies the affected component and weakness but does not disclose the parsing routine or unchecked length operation that corrupts heap memory. Exploitation requires user interaction; successful code execution can compromise confidentiality, integrity, and availability.
