CVE-2017-18272

Estado: ModificadaMedia (6.5)—

Hay un uso de memoria previamente liberada en ImageMagick 7.0.7-16 Q16 x86_64 2017-12-25 en la función ReadOneMNGImage en coders/png.c. Esta vulnerabilidad permite que los atacantes provoquen una denegación de servicio (DoS) mediante un archivo de imagen MNG manipulado que se gestiona de manera incorrecta durante una llamada MngInfoDiscardObject.
