Descriptions
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Samsung Galaxy S8 G950FXXU1AQL5. User interaction is required to exploit this vulnerability in that the target must have their cellular radios enabled. The specific flaw exists within the handling of IPCP headers. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length, stack-based buffer. An attacker can leverage this vulnerability to execute code under the context of the baseband processor. Was ZDI-CAN-5368.
Esta vulnerabilidad permite que los atacantes remotos ejecuten código arbitrario en instalaciones vulnerables de Samsung Galaxy S8 G950FXXU1AQL5. Se requiere de interacción del usuario para explotar esta vulnerabilidad en la que el objetivo debe tener la radio de su móvil habilitada. Este error en concreto existe en el manejo de cabeceras IPCP. Este error deriva de la falta de validación adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos en un búfer basado en pila con un tamaño determinado. Un atacante podría aprovecharse de esta vulnerabilidad para ejecutar código en el contexto del procesador de banda base. Anteriormente era ZDI-CAN-5368.
