Code execution via image-dimension integer overflow
Published Feb 24, 2022 · Updated Aug 2, 2024
Integer overflow in Blender before 2.83.19, before 2.93.8, and before 3.1 allows attackers to execute code via a crafted 2D image. IMB_flipx and IMB_flipy multiply image dimensions and pixel-stride values in narrow integer intermediates that silently overflow before pointer arithmetic. A user must load the image; the resulting out-of-bounds read or attacker-directed write discloses process data or executes code in Blender's context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
