Summary
PDF-XChange Editor App Untrusted Pointer Dereference 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 handling of App objects. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-20729.

La falla espec\u00edfica existe en el manejo de objetos de la aplicaci\u00f3n. El problema se debe a la falta de validaci\u00f3n adecuada de un valor proporcionado por el usuario antes de eliminar la referencia a \u00e9l como puntero.
