Sin perder tiempo y como es de costumbre con la primera semana oficial del mes, ya los parchos de seguridad de Android correspondientes para abril fueron publicados.
Google proporcionó hoy detalles sobre sus parches de seguridad de abril de 2017 para dispositivos Android trabajados desde el mes pasado y los parches o arreglos conectan un número significativo de huecos de seguridad que amenazan o amenazaban a todos los dispositivos Android.
Para este mes, Google encontró más de 60 vulnerabilidades, de las que clasificó a ocho como crítico, o capaz de ejecutar código de forma remota. Muchos de los problemas están relacionados con hardware específico y los drivers asociados que los controlan, como un controlador de pantalla táctil de MediaTek y un controlador de motor de criptografía de Qualcomm.

Google está lanzado dos series de las mejoras para cubrir estas vulnerabilidades, una con fecha 1 de abril y la segunda con fecha de 5 de abril. Como siempre, Google está haciendo disponible las mejoras directamente a sus propios dispositivos de marca Nexus y Pixel primero.
Como ya es de costumbre, la gigante de Internet afirma no tener evidencia que ninguno de estos agujeros de seguridad ha sido explotado en la calle y se les implora a sus socios OEM en adoptar las mejoras.
*Equipos actualizados desde Android 7.0 en adelante no estaban ya en riesgo
**Qualcomm resolvió estos issues con socios durante sus própios boletines entre 2014 y 2017
