Code execution via unchecked TGA size multiplication
Published Aug 24, 2021 · Updated Aug 4, 2024
Integer overflow in PLIB 1.8.5 and earlier allows context-dependent attackers to execute arbitrary code via a crafted TGA image. ssgLoadTGA() multiplies attacker-controlled bit depth, width, and height values to size a heap allocation without checking whether the product wraps. Exploitation requires an application using PLIB to open the image, and successful memory corruption executes code in that application's context.
