Descriptions

The Xinput module (modules/im/ximcp/imLcIm.c) in X.Org libX11 1.0.2 and 1.0.3 opens a file for reading twice using the same file descriptor, which causes a file descriptor leak that allows local users to read files specified by the XCOMPOSEFILE environment variable via the duplicate file descriptor.

El módulo Xinput (modules/im/ximcp/imLcIm.c) en X.Org libX11 1.0.2 y 1.0.3 abre un fichero para lectura dos veces utilizando el mismo descriptor de fichero, que provoca un agujero en los descriptores de fichero permitiendo a los usuarios locales, leer ficheros concretos con la variable de entorno XCOMPOSEFILE mediante un descriptor de fichero duplicado.
