      "value": "Ashlar-Vellum Cobalt Out-Of-Bounds Access Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Cobalt. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.\n\nThe specific flaw exists within the parsing of IGS files. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.\n. Was ZDI-CAN-18006."

Esta vulnerabilidad permite a atacantes remotos ejecutar c\u00f3digo arbitrario en las instalaciones afectadas de Ashlar-Vellum Cobalt. Se requiere la interacci\u00f3n del usuario para aprovechar esta vulnerabilidad, ya que el objetivo debe visitar una p\u00e1gina maliciosa o abrir un archivo malicioso. La falla espec\u00edfica existe en el an\u00e1lisis de archivos IGS. El problema se debe a la falta de una validaci\u00f3n adecuada de los datos proporcionados por el usuario, lo que puede provocar un acceso a la memoria m\u00e1s all\u00e1 del final de un b\u00fafer asignado. Un atacante puede aprovechar esta vulnerabilidad para ejecutar c\u00f3digo en el contexto del proceso actual. Era ZDI-CAN-18006."
