(you can usually also just write the address a ton of times, eg: "\x88\xf6\xff\xbf"*200 ) That pretty much covers the basics of buffer overflows, stay tuned for a ROP tutorial (Return Oriented Programming) which can also be used to solve buffer. If we have a write - where vulnerability (where we can't control what we write), we can use that to modify the size of the PALETTE object by modifying 1 byte in the cEntries field, the only requirement is that we can precisely set the location, and it should be something other than 0.
