En el stack inal\u00e1mbrico de chips Qualcomm se han identificado<\/a><\/noindex> tres vulnerabilidades que se presentan bajo el nombre en clave \u00abQualPwn\u00bb. El primer problema (CVE-2019-10539) permite atacar dispositivos basados en la plataforma Android de forma remota a trav\u00e9s de Wi-Fi. El segundo problema se encuentra en el firmware propietario con la pila inal\u00e1mbrica de Qualcomm y permite acceder al m\u00f3dem baseband (CVE-2019-10540). El tercer problema hay<\/a><\/noindex> est\u00e1 en el controlador icnss (CVE-2019-10538) y permite ejecutar c\u00f3digo en el nivel del n\u00facleo de la plataforma Android. En caso de que se exploten con \u00e9xito las vulnerabilidades mencionadas, el atacante puede controlar remotamente el dispositivo del usuario en el que Wi-Fi est\u00e1 activo (para el ataque, se requiere que la v\u00edctima y el atacante est\u00e9n conectados a la misma red inal\u00e1mbrica).<\/p>\n

La posibilidad de ataque ha sido demostrada para los smartphones Google Pixel 2 y Pixel 3. Seg\u00fan los investigadores, el problema potencialmente afecta a m\u00e1s de 835,000 dispositivos basados en SoC Qualcomm Snapdragon 835 y chips m\u00e1s nuevos (a partir de Snapdragon 835, el firmware WLAN fue integrado con el subsistema del m\u00f3dem y funcionaba como una aplicaci\u00f3n aislada en el espacio del usuario). Por los datos<\/a><\/noindex> Qualcomm, el problema afecta a varias docenas de chips diferentes. <\/p>\n

En la actualidad, solo hay informaci\u00f3n general sobre las vulnerabilidades, y los detalles est\u00e1 previsto<\/a><\/noindex> se revelar\u00e1n el 8 de agosto en la conferencia Black Hat. Las empresas Qualcomm y Google fueron notificadas sobre los problemas en marzo y ya han emitido correcciones (Qualcomm inform\u00f3 sobre los inconvenientes en el informe de junio<\/a><\/noindex>, mientras que Google abord\u00f3 las vulnerabilidades en el actualizaci\u00f3n de agosto<\/a><\/noindex> de la plataforma Android). Se recomienda a todos los usuarios de dispositivos con chips Qualcomm que instalen las actualizaciones disponibles.<\/p>\n

Adem\u00e1s de los problemas relacionados con los chips Qualcomm, la actualizaci\u00f3n de agosto de la plataforma Android tambi\u00e9n resolvi\u00f3 una vulnerabilidad cr\u00edtica (CVE-2019-11516) en el stack Bluetooth de Broadcom, que permite al atacante ejecutar su c\u00f3digo en el contexto de un proceso privilegiado mediante el env\u00edo de una solicitud de transmisi\u00f3n de datos especialmente dise\u00f1ada. Tambi\u00e9n se ha solucionado una vulnerabilidad en los componentes del sistema de Android (CVE-2019-2130), que permite ejecutar c\u00f3digo con privilegios elevados al procesar archivos PAC especialmente creados.<\/p>\n
