Summary

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.
