Descripción
Apple iOS, macOS y iPadOS contienen una vulnerabilidad de escritura fuera de límites en CoreGraphics que podría derivar en la ejecución de código arbitrario.
Acción recomendada
Aplicar las mitigaciones del fabricante y revisar los equipos afectados en busca de señales de compromiso (triaje forense) antes de darlos por remediados. Evaluar la exposición a internet de cada activo para priorizar la aplicación de parches. En servicios en la nube, seguir las recomendaciones de seguridad del proveedor; si no hay mitigaciones disponibles, discontinuar el uso del producto.
