Descriptions

The WriteImages function in magick/constitute.c in ImageMagick before 6.9.2-4 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted image file.

La función WriteImages en magick/constitu.c en ImageMagick en versiones anteriores a 6.9.2-4 permite a atacantes remotos provocar una denegación de servicio (referencia a puntero NULL) a través de un archivo de imagen manipulado.

ImageMagick is an image display and manipulation tool for the X Window System that can read and write multiple image formats. Security Fix: It was discovered that ImageMagick did not properly sanitize certain input before using it to invoke processes. A remote attacker could create a specially crafted image that, when processed by an application using ImageMagick or an unsuspecting user using the ImageMagick utilities, would lead to arbitrary execution of shell commands with the privileges of the user running the application.
