Description Zack Miele 2024-05-08 20:56:36 UTC
libmodbus v3.1.10 is vulnerable to Buffer Overflow via the modbus_write_bits function. This issue can be triggered when the function is fed with specially crafted input, which leads to out-of-bounds read and can potentially cause a crash or other unintended behaviors.
