This vulnerability allows remote attackers to disclose sensitive information on affected installations of PDF-XChange Editor. 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 U3D files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.

Esta vulnerabilidad permite a atacantes remotos divulgar informaci\u00f3n confidencial sobre las instalaciones afectadas del editor PDF-XChange. Para explotar esta vulnerabilidad, se requiere la interacci\u00f3n del usuario, ya que el objetivo debe visitar una p\u00e1gina maliciosa o abrir un archivo malicioso. La falla espec\u00edfica se encuentra en el an\u00e1lisis de archivos U3D. El problema se debe a la falta de una validaci\u00f3n adecuada de los datos proporcionados por el usuario, lo que puede provocar una lectura m\u00e1s all\u00e1 del final de un objeto asignado.
