Estado: ModificadaAlta (7.1)—

En read_paint de ttcolr.c, existe una posible lectura fuera de límites debida a un desbordamiento de búfer en el heap. Esto podría provocar la divulgación local de información sin que se necesiten privilegios de ejecución adicionales. No es necesaria la interacción del usuario para la explotación.Product: AndroidVersions: Android-13Android ID: A-254803162
