Title
seladb PcapPlusPlus Modbus Protocol ModbusLayer.h getLength heap-based overflow
Summary
A security flaw has been discovered in seladb PcapPlusPlus 25.05. This impacts the function pcpp::ModbusLayer::getLength in the library Packet++/header/ModbusLayer.h of the component Modbus Protocol Handler. The manipulation of the argument length results in heap-based buffer overflow. The attack can be launched remotely. A high complexity level is associated with this attack. The exploitability is said to be difficult. The exploit has been released to the public and may be used for attacks. The patch is identified as 4c90c3e3418a2b09dc82b7ca5775e9c1e22fe454.
