Descriptions
The functions ReadDCMImage in coders/dcm.c, ReadPWPImage in coders/pwp.c, ReadCALSImage in coders/cals.c, and ReadPICTImage in coders/pict.c in ImageMagick 7.0.8-4 do not check the return value of the fputc function, which allows remote attackers to cause a denial of service via a crafted image file.
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.
