      "value": "XnSoft XnView Classic RWZ File Parsing Integer Underflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of XnSoft XnView Classic. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.\n\n\nThe specific flaw exists within the parsing of RWZ files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22913."

Esta vulnerabilidad permite a atacantes remotos ejecutar c\u00f3digo arbitrario en las instalaciones afectadas de XnSoft XnView Classic. Se requiere la interacci\u00f3n del usuario para explotar 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 RWZ. El problema es el resultado de la falta de una validaci\u00f3n adecuada de los datos proporcionados por el usuario, lo que puede provocar un desbordamiento de enteros antes de escribir en la memoria. Un atacante puede aprovechar esta vulnerabilidad para ejecutar c\u00f3digo en el contexto del proceso actual. Era ZDI-CAN-22913."
