Heap buffer overflow in the yr_object_array_set_item() function in object.c in YARA 3.x allows a denial-of-service attack by scanning a crafted .NET file.
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.
