Heap-based buffer overflow in Automated Solutions Modbus/TCP Master OPC Server before 3.0.2 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a MODBUS response packet with a crafted length field.
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.
