boot1

Summary Description Successful exploitation result Fixed in boot1 version Discovered Discovered by
Poor System Menu TMD size check boot1 loads the System Menu's TMD for verification and loading, and it attempts to check the size. However, instead of checking if size > capacity, it checks if size > size, which is always false, resulting in a buffer overflow. Code execution under boot1 Unfixed August 2017 Nocash

System Menu

Summary Description Successful exploitation result Discovered Discovered by
DS games are not patched to verify overlays. While the System Menu checks all cartridge overlays to prevent unauthorized software, no such check exists when the overlays are actually loaded, despite an MIOS-like patcher being possible to implement. By changing the overlay after it is checked, it is possible to run arbitrary code. Code execution under any DS game with overlays. January 2010 Datel, blasty (by reverse engineering Action Replay)
