Descriptions

In ImageMagick 7.0.7-23 Q16 x86_64 2018-01-24, there is a heap-based buffer over-read in ReadSUNImage in coders/sun.c, which allows attackers to cause a denial of service (application crash in SetGrayscaleImage in MagickCore/quantize.c) via a crafted SUN image file.

Hay una sobrelectura de búfer basada en memoria dinámica (heap) en ImageMagick 7.0.7-23 Q16 x86_64 2018-01-24, en ReadSUNImage en coders/sun.c que permite que atacantes provoquen una denegación de servicio (cierre inesperado de la aplicación en SetGrayscaleImage en MagickCore/quantize.c) mediante un archivo de imagen SUN manipulado.

It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.
