This vulnerability allows remote attackers to execute arbitrary code 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 GIF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.

Esta vulnerabilidad permite a atacantes remotos ejecutar c\u00f3digo arbitrario en 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 GIF. El problema se debe a la falta de una validaci\u00f3n adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos a un b\u00fafer basado en mont\u00f3n de longitud fija.
