CVE-2018-16643

Estado: ModificadaMedia (6.5)—

Las funciones ReadDCMImage en coders/dcm.c, ReadPWPImage en coders/pwp.c, ReadCALSImage en coders/cals.c y ReadPICTImage en coders/pict.c en ImageMagick 7.0.8-4 no comprueban el valor de retorno de la función fputc, lo que permite que los atacantes remotos provoquen una denegación de servicio (DoS) mediante un archivo de imagen manipulado.
