Heap-based buffer overflow in XnView before 1.99 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted ImageLeftPosition value in an ImageDescriptor structure in a GIF image.
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.
