Descriptions

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Samsung Galaxy S10 Firmware G973FXXS3ASJA, O(8.x), P(9.0), Q(10.0) devices with Exynos chipsets. User interaction is required to exploit this vulnerability in that the target must answer a phone call. The specific flaw exists within the Call Control Setup messages. 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 in the context of the baseband processor. Was ZDI-CAN-9658.

Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en las instalaciones afectadas de los dispositivos Samsung Galaxy S10 G973FXXS3ASJA, versiones de firmware O(8.x), P(9.0), Q(10.0) con chipsets Exynos. Es requerida una interacción del usuario para explotar esta vulnerabilidad, ya que el objetivo debe responder a una llamada telefónica. El fallo específico se presenta dentro de los mensajes Call Control Setup. El problema resulta de la falta de comprobación apropiada de la longitud de los datos suministrados por el usuario antes de copiarlos en un búfer de longitud fija en la región stack de la memoria. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del procesador de banda base. Fue ZDI-CAN-9658.
