CVE-2021-26825Public exploit

Code execution via overflowing TGA size calculation

Published Feb 8, 2021 · Updated Aug 3, 2024

Integer overflow in Godot Engine 3.2 and earlier allows attackers to execute code or crash an application via a crafted TGA file. ImageLoaderTGA::load_image() multiplies untrusted image width, height and pixel depth to size a buffer without checking overflow, then decodes attacker-controlled pixel data into it. Opening or importing the file is required; successful exploitation runs code in the application's context, while malformed inputs can instead crash it.
