      "value": "PDF-XChange Editor PRC File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. 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 PRC files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26734."

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 PRC. El problema se debe a la falta de una validaci\u00f3n adecuada de los datos proporcionados por el usuario, lo que puede provocar una escritura m\u00e1s all\u00e1 del l\u00edmite del b\u00fafer asignado. Un atacante puede aprovechar esta vulnerabilidad para ejecutar c\u00f3digo en el contexto del proceso actual. Anteriormente, se denomin\u00f3 ZDI-CAN-26734."
