Code execution via media-processing heap overflow
Published Dec 12, 2023 · Updated Jan 1, 2025
Heap-based buffer overflow in Windows Media on affected Windows releases allows attackers to execute code after user interaction. Microsoft identifies the weakness class but has not disclosed the affected parser or the operation that mishandles media data. Exploitation requires user interaction on the affected host; the delivery path and resulting execution context remain undisclosed.
