RPG Maker Bug Unleashes Integer Overflow Apocalypse: Brace for Impact!
An RPG Maker save file can cause chaos in liblcf’s ReadInt function, thanks to a crafty integer overflow. The result? Out-of-bounds reads, memory mishaps, and potential denial of service. Who knew saving your game could lead to such a digital drama?
Hot Take:
Move over, RPG Maker. It seems like your save files are becoming the newest weapon of mass corruption! Who knew your harmless little pixelated world could pack such a punch? It’s like the digital version of finding out your grandma is a secret ninja. Beware of seemingly innocent `.lsd` files; they might just crash your dreams – literally!
Key Points:
- Vulnerability in liblcf v0.8.1 allows for integer overflow.
- The flaw is triggered by a crafted RPG Maker `.lsd` save file.
- Involves unbounded shifts and accumulation loops in `ReadInt()`.
- Results in out-of-bounds memory reads and potential denial of service.
- Proof of concept involves a malformed integer containing 11 bytes of `0xFF`.
