Official description
A heap-based buffer overflow was found in GIMP’s GIF export plug-in. Exporting an image with very large width and height can cause 32-bit overflow when computing the pixel buffer size. The plug-in allocates a buffer based on the wrapped value while GEGL writes using the true image extent, rooted in integer overflow
