"value": "In Artifex Ghostscript through 9.25, the setpattern operator did not properly validate certain types. A specially crafted PostScript document could exploit this to crash Ghostscript or, possibly, execute arbitrary code in the context of the Ghostscript process. This is a type confusion issue because of failure to check whether the Implementation of a pattern dictionary was a structure type."

Un documento PostScript especialmente manipulado podr\u00eda explotar esto para provocar el cierre inesperado de Ghostscript o ejecutar c\u00f3digo arbitrario en el contexto del proceso Ghostscript. Este es un problema de confusi\u00f3n de tipos debido al error a la hora de comprobar si la implementaci\u00f3n de un diccionario de patrones era un tipo de estructura."
