A buffer overflow vulnerability exists in the GIF image parsing functionality of SDL2_image-2.0.2. A specially crafted GIF image can lead to a buffer overflow on a global section. An attacker can display an image to trigger this vulnerability.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
