Stack-based buffer overflow in the imb_loadhdr function in Blender 2.45 allows user-assisted remote attackers to execute arbitrary code via a .blend file that contains a crafted Radiance RGBE 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.
