CVE-2023-23402

Code execution via crafted media file double-free

Published Mar 14, 2023 · Updated Jan 1, 2025

Double-free in Windows Media on affected Microsoft Windows releases allows attackers to execute code through a crafted media file. Windows Media releases the same memory allocation twice while processing the file, allowing heap corruption; Microsoft has not disclosed the specific parser or object involved. A user must open the file, and successful code executes with that user's rights.
