Descriptions

An exploitable code execution vulnerability exists in the rendering functionality of Nitro Pro 13.13.2.242 and 13.16.2.300. When drawing the contents of a page and selecting the stroke color from an 'ICCBased' colorspace, the application will read a length from the file and use it as a loop sentinel when writing data into the member of an object. Due to the object member being a buffer of a static size allocated on the heap, this can result in a heap-based buffer overflow. A specially crafted document must be loaded by a victim in order to trigger this vulnerability.

Se presenta una vulnerabilidad de ejecución de código explotable en la funcionalidad de renderizado de Nitro Pro versiones 13.13.2.242 y 13.16.2.300. Al dibujar el contenido de una página y seleccionar el color de trazo de un espacio de color "ICCBased", la aplicación leerá una longitud del archivo y lo usará como un centinela de bucle cuando escribe datos en el miembro de un objeto. Debido a que el miembro del objeto es un búfer de tamaño estático asignado en la pila, esto puede resultar en un desbordamiento del búfer en la región heap de la memoria. La víctima debe cargar un documento especialmente diseñado para activar esta vulnerabilidad
