A stack-based buffer overflow in Panasonic Control FPWIN Pro versions 7.6.0.3 and all previous versions may allow arbitrary code execution when opening specially crafted project files.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
The product writes data past the end, or before the beginning, of the intended buffer.
