Descriptions

A divide-by-zero flaw was found in ImageMagick 6.9.11-57 and 7.0.10-57 in gem.c. This flaw allows an attacker who submits a crafted file that is processed by ImageMagick to trigger undefined behavior through a division by zero. The highest threat from this vulnerability is to system availability.

Se encontró un fallo en ImageMagick en el archivo MagickCore/gem.c. Un atacante que envía un archivo diseñado que es procesado por ImageMagick podría desencadenar un comportamiento indefinido en la forma de una división matemática por cero. Esto probablemente conllevaría a un impacto en la disponibilidad de la aplicación, pero podría causar potencialmente otros problemas relacionados con un comportamiento indefinido. Este fallo afecta a ImageMagick versiones anteriores a 7.0.10-56
