CVE-2019-12980

Estado: ModificadaMedia (6.5)—

En Ming (aka libming) versión 0.4.8, hay un desbordamiento de enteros (causado por un desplazamiento izquierdo fuera de rango) en la función SWFInput_readSBits en blocks/input.c. Los atacantes remotos podrían aprovechar esta vulnerabilidad para causar una denegación de servicio a través de un archivo swf diseñado.
