| KFH frame count overflow
| The KFH frame count field should not be >= 0x3E8, but it wasn't checked and so uncontrolled data were written over pointers, causing an unexploitable crash.

| KMI paper color overflow
| Paper color field (and similar color fields) in KMI chunks was not checked, a too high value caused a jump to an uncontrolled location.

|-
| KSN BGM data size overflow
| The size of the BGM data in the KSN chunk was not checked, it was used in a memcpy so with a big enough size one could overwrite a thread stack on linear mem and achieve ROP (notehax v1).

|-
| KMC chunk unchecked
| The KMC chunk was not verified at all, the CRC32 and the size were not checked. A big enough size caused an integer overflow and made the game read the file backward.

| KMI layer size unchecked
| The 3 layer size fields in KMI chunks were not checked, leading to some crashes in the editor.

| Bad "queue" implementation
| When a KWZ was parsed, frames were copied in a kind of queue, bounds were not checked obviously, so with the KMI layer size flaw one was able to fill completely the queue, then write past the buffer and overwrite a heap chunk header (notehax v2). This is not possible anymore, the queue cannot be filled because layer sizes are checked. Moreover each time an element is removed from the queue, the whole content is memmoved *facepalm*.
