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.

Delta Electronics Delta Industrial Automation DOPSoft version 4.00.04 and prior performs read operations on a memory buffer where the position can be determined by a value read from a .dpa file. This may cause improper restriction of operations within the bounds of the memory buffer, allow remote code execution, alter the intended control flow, allow reading of sensitive information, or cause the application to crash.

A Stack-based Buffer Overflow issue was discovered in Delta Electronics Delta Industrial Automation DOPSoft, Version 4.00.01 or prior. Stack-based buffer overflow vulnerabilities caused by processing specially crafted .dop or .dpb files may allow an attacker to remotely execute arbitrary code.
