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.
Due to a large number of issues discovered in GhostScript that prevent it from being used by ImageMagick safely, this update includes a default policy change that disables support for the Postscript and PDF formats in ImageMagick. This policy can be overridden if necessary by using an alternate ImageMagick policy configuration. It was discovered that several memory leaks existed when handling certain images in ImageMagick. An attacker could use this to cause a denial of service. Various other issues were also addressed.
