Panasonic FPWIN Pro 5.x through 7.x before 7.130 allows local users to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact by triggering a crafted index value, as demonstrated by an integer overflow.
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.
