This page lists vulnerabilities / exploits for 3DS applications and applets. Exploiting these initially results in ROP.
Non-system applications

---|---|---|---|---|---|---|
The Legend of Zelda: Ocarina of Time 3D | UTF-16 name string buffer overflow via unchecked u8 length field | The u8 at offfset 0x2C in the savefile is the character-length of the UTF-16 string at offset 0x1C. When copying this string, it's essentially a memory-copy with lenval*2, not a string-copy. This can be used to trigger buffer overflows at various locations depending on the string length.
Length value>=0xCD causes a crash while loading the saveslot, via a heap buffer overflow. When value is >=0x6E it crashes when saving the saveslot. With value >=0x9A, it crashes via stack-smash in-game once any dialogs are opened(touching buttons on the touch-screen to enter certain menu(s) can trigger it too). |

---|---|---|---|---|---|
3DS System Settings DS profile string stack-smash | Too long or corrupted strings (01Ah 2 Nickname length in characters 050h 2 Message length in characters) in the NVRAM DS user settings (System Settings->Other Settings->Profile->Nintendo DS Profile) cause it to crash in 3DS-mode due to a stack-smash. The DSi is not vulnerable to this, DSi launcher(menu) and DSi System Settings will reset the NVRAM user-settings if the length field values are too long(same result as when the CRCs are invalid). TWL_FIRM also resets the NVRAM user-settings when the string-length(s) are too long. | 7.0.0-13 | 7.0.0-13 | 2012 | Ichfly |
