CVE-2018-4884

Estado: ModificadaMedia (6.5)—

Se ha descubierto un problema en Adobe Acrobat Reader 2018.009.20050 y anteriores, 2017.011.30070 y anteriores y 2015.006.30394 y anteriores. Esta vulnerabilidad ocurre como resultado de un cálculo que lee datos más allá del final del búfer objetivo; el cálculo forma parte del motor de conversión de imágenes cuando gestiona datos Enhanced Metafile Format (EMF) que embebe una imagen en formato de archivo bitmap (BMP). Un ataque con éxito podría conducir a la exposición de datos sensibles.
