Description

Delta Electronics Delta Industrial Automation DOPSoft version 4.00.04 and prior utilizes a fixed-length heap 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.

• CWE-122Heap-based Buffer OverflowA heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
• CWE-119Improper Restriction of Operations within the Bounds of a Memory BufferThe 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.
