| SmileBASIC 3.x
| Subscripted TIME$/DATE$ allow write access to DATA/BSS
| Utf-16 characters can be assigned to subscripted TIME$/DATE$ interpreter sysvars which results in write-only access to all of DATA and some BSS in userland.
TIME$[0]/DATE$[0] actually point to somewhere in rodata, and an overly large subscript can be used to write well past it and into the aforementioned areas. Demo [https://github.com/zoogie/smilehax-IIe here.]

| Buffer overflow via unchecked string size
| Buffer overflow via unchecked string size
| The game stores some utf-16 messages in the savefile. Right before the message is the length(u32) for the string, the game uses this size to memcpy the message from the savefile to the stack without checking the length. This allows one to overwrite to some function addresses on the stack and form a rop chain.

| String Buffer Overflow via unchecked string length
| The game stores plaintext profile names in the savefile. The profile names are strcpy/memcpy to different areas of the game's functions in the stack. Using a large extensive profile name, a user can overwrite some stack-registers and point to stack buffer addresses to eventually gain control of the stack to lead and form a rop-chain.

| Picross 3D: Round 2
| Out of bounds array access allowing to point to fabricated objects and vtable
| Game only checks save header. With the last interacted save slot index at +0xb270 in the save data unchecked we can achieve a predictable out of bounds access, as well inserting ROP data without detecting save corruption. Game references an object from an array of 3 elements and passes it to a function that will read object pointers and hit a vtable call. With a copy save data left in memory and a properly calculated index, we can point to a fake object position in the save, vtable jump to a stack pivot and start the ROP chain.

* "Angry Birds Star Wars": Strings in the savefile are preceded by their lengths. These strings are never stored on the stack and are memcpy'd into heap memory. If the size is invalid the alloc will fail and thus the memcpy will operate on a nullptr resulting in a useless data abort.
* "Gem Smashers": Overwriting the savefile with random bytes results in useless crashes.
* "Luxor:" Strings/plaintext in the savefile are present and these's no checks. Overwriting the whole save (excluding the header), with /dev/random cause a useless crash.
* "Luv Me Buddies Wonderland:" Doesn't crash at all with the entire savedata overwritten. Overwriting some areas, points to useless nulls

| 3DS [[System Settings]] stack smash via title strings in [[DSiWare_Exports]]
| DSiWare export banners contain 16 consecutive 0x100 byte, utf-16 game title strings for different languages. Nintendo correctly limits the string's max length by placing a NULL at str[127] before it's copied to the stack. However, they didn't allocate enough space for all 128 wchars (char/wchar type confusion?), so an attacker can craft a valid full-length string that will crash the stack at about str+0xEC. ROP execution can then be obtained from this crash in DSiWare Data Management as demonstrated [https://github.com/zoogie/Bannerbomb3 here].
Interesting note: A line feed wchar (00 0A) at any point in the string before the crash offset will prevent the crash from occurring.

| 3DS SAFE_MODE [https://www.3dbrew.org/wiki/System_Settings#System_Updater System Updater] stack smash from proxy-url string
| During [[Recovery Mode]] and after all 3 wifi slots fail to find an access point for sysupdate, a user is permitted to access the wifi settings mode to make changes. Here, if the proxy-url field string's NULL terminator had been altered beforehand, a stack smash can occur when the user selects Proxy Settings -> Detailed Setup and the corrupted url string is displayed.
This is a difficult crash to control because the url string is converted from ascii to utf-16 between the slot and stack, effectively reducing the available gadgets to 0.4% of the normal amount. It's possible to improvise an "escape" using an eoreq pc w/shift gadget to combine registers and form a jump that can access 1/2 of all available gadgets.
Because this exploit runs *under* SAFE_MODE, it's possible to run safehax with one's choice of k11 and arm9 hax. Prerequisite: a userland exploit with cfg:s/i access to modify the wifi slot. A demonstration can be viewed [https://github.com/zoogie/unSAFE_MODE here].

| When creating an audio decoder object for the moflex movie player, if the audio codec is PCM16, the application uses an uninitialized value as a pointer. One can spray the heap to get control of that pointer and achieve ROP.

| u8 brightness setting OOB index (menuhax67)
| Config block 0x50001, which contains a u8 brightness setting that indexes a table of u32 addresses, can be set to an out-of-bounds index (it's normally 1-5). Located within cfg block 0x50009, there exists a single controllable u32 that's located within the u8's range. With these set properly, one can eventually redirect a function pointer to an address of their choice. This is triggered after the Home Menu quick launch tab is activated. POC [https://github.com/zoogie/menuhax67 here].
