Descriptions

An issue was discovered in Foxit Reader before 10.1.1 (and before 4.1.1 on macOS) and PhantomPDF before 9.7.5 and 10.x before 10.1.1 (and before 4.1.1 on macOS). An attacker can spoof a certified PDF document via an Evil Annotation Attack because the products fail to consider a null value for a Subtype entry of the Annotation dictionary, in an incremental update.

Se detectó un problema en Foxit Reader versiones anteriores a 10.1.1 (y versiones anteriores a 4.1.1 en macOS) y PhantomPDF versiones anteriores a 9.7.5 y versiones 10.x anteriores a 10.1.1 (y versiones anteriores a 4.1.1 en macOS). Un atacante puede falsificar un documento PDF certificado por medio de un Ataque de Anotación Maliciosa porque los productos no consideran un valor nulo para una entrada Subtype del diccionario Annotation, en una actualización incremental.
