This may cause the program to crash when a long character string is used. 10 allows to overflow the buffer allocated for the Modbus response if the Buffer overflows are one of the most difficult category of bugs to both detect and locate on an embedded system. This vulnerability occurs when the software attempts to send a reply to a Modbus request that contains an unexpected length, potentially leading to compromised system integrity and unauthorized A buffer overflow is basically when a crafted section (or buffer) of memory is written outside of its intended bounds. If an attacker can manage to make this happen from outside of a program it can cause security problems as it could potentially allow them to manipulate arbitrary memory locations, although many modern operating systems protect libmodbus v3.
