Think of it like receiving an official-looking package where the delivery guy forgot to check what’s inside — you open it, and suddenly, there’s a surprise party you definitely didn’t want! The issue stems from improper validation of array indices when parsing SFD files, leading to a write past an allocated array. This oversight opens the door for remote code execution in the context of the user.
