Descriptions

PDF-XChange Editor EMF 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.

The specific flaw exists within the parsing of EMF files. Crafted data in a EMF can trigger 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-18790.

Vulnerabilidad de ejecución remota de código de escritura fuera de los límites en el análisis de archivos EMF del editor PDF-XChange. Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en instalaciones afectadas de PDF-XChange Editor. Se requiere la interacción del usuario para aprovechar esta vulnerabilidad, ya que el objetivo debe visitar una página maliciosa o abrir un archivo malicioso. La falla específica existe en el análisis de archivos EMF. Los datos elaborados en un EMF pueden desencadenar una escritura más allá del final de un búfer asignado. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. Era ZDI-CAN-18790.
