holy FUCK.

Windows Snipping Tool is vulnerable to Acropalypse too.

An entirely unrelated codebase.

The same exploit script works with minor changes (the pixel format is RGBA not RGB)

Tested myself on Windows 11

@ItsSimonTime @David3141593 I've got a fun one for you all to look at.

I opened a 198 byte PNG with Microsoft's Snipping Tool, chose "Save As" to overwrite a different PNG file (no editing), and saves a 4,762 byte file with all that extra after the PNG IEND chunk.

Sounds similar :D
