Sistemas Afectados

1. Descripción

   Mandriva liberó una actualización para xine-lib. Esta repara una vulnerabilidad que podría explotarse por personas maliciosas para comprometer el sistema de un usuario.

   Ulf Harnhammar descubrió un error de formato de cadena en el modulo de CDDB que maneja la cache en la biblioteca de Xine, esta es utilizada por paquetes como xine-ui, totem-xine, y gxine. Podría ser explotado para ejecutar código arbitrario al engañar a un usuario a ingresar a un servidor CDDB malicioso.
