Descriptions

Integer overflow in the GatewayService component in 3S CoDeSys 3.4 SP4 Patch 2 allows remote attackers to execute arbitrary code via a large size value in the packet header, which triggers a heap-based buffer overflow.

Desbordamiento de entero en el componente GatewayService en 3S CoDeSys v3.4 Parche 2 SP4 permite a atacantes remotos ejecutar código arbitrario mediante un valor de gran tamaño en la cabecera del paquete, lo que provoca un desbordamiento de búfer basado en heap (montón).
