Delta Electronics Delta Industrial Automation DOPSoft version 4.00.04 and prior utilizes a fixed-length stack buffer where a value larger than the buffer can be read from a .dpa file into the buffer, causing the buffer to be overwritten. This may allow remote code execution or cause the application to crash.
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 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.
