CVE-2018-9133

Estado: ModificadaMedia (6.5)—

ImageMagick 7.0.7-26 Q16 tiene una iteración excesiva en las funciones DecodeLabImage y EncodeLabImage (coders/tiff.c), lo que resulta en un bloqueo de varios minutos con un archivo PoC pequeño. Los atacantes remotos podrían aprovechar esta vulnerabilidad para provocar una denegación de servicio (DoS) mediante un archivo tiff manipulado.
