An issue was discovered in Artifex Ghostscript before 10.03.1. contrib/opvp/gdevopvp.c allows arbitrary code execution via a custom Driver library, exploitable via a crafted PostScript document. This occurs because the Driver parameter for opvp (and oprp) devices can have an arbitrary name for a dynamic library; this library is then loaded.
Se descubrió un problema en Artifex Ghostscript antes de la versión 10.03.1. contrib/opvp/gdevopvp.c permite la ejecución de código arbitrario a través de una librería de controladores personalizada, explotable a través de un documento PostScript manipulado. Esto ocurre porque el parámetro Controlador para dispositivos opvp (y oprp) puede tener un nombre arbitrario para una librería dinámica; luego se carga esta librería.
A flaw was found in Ghostscript. The "Driver" parameter for the "opvp"/"oprp" device specifies the name of a dynamic library and allows any library to be loaded. This flaw allows a malicious user to send a specially crafted document that, when processed by Ghostscript, could potentially lead to arbitrary code execution with the privileges of the Ghostscript process on the system.
