Descriptions

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Foxit Reader 10.1.1.37576. 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 handling of U3D objects embedded in PDF 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. Was ZDI-CAN-13241.

Esta vulnerabilidad permite a atacantes remotos revelar información confidencial sobre instalaciones afectadas de Foxit Reader versión 10.1.1.37576. Es requerida una interacción del usuario para explotar esta vulnerabilidad, ya que el objetivo debe visitar una página maliciosa o abrir un archivo malicioso. El fallo específico se presenta dentro del manejo de objetos U3D insertados en archivos PDF. El problema es debido a una falta de comprobación apropiada de los datos suministrados por el usuario, lo que puede resultar en una lectura más allá del final de un objeto asignado. Un atacante puede aprovechar esto junto con otras vulnerabilidades para ejecutar código arbitrario en el contexto del proceso actual.
