Descriptions

X.org libXi 1.7.1 and earlier allows X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to an unexpected sign extension in the XListInputDevices function.

X.org LibXi v1.7.1 y anteriores permite a los servidores X activar la asignación de memoria insuficiente y provocar un desbordamiento de búfer a través de vectores relacionados con una extensión de signo inesperada en la función XListInputDevices.

A buffer overflow flaw was found in the way the XListInputDevices() function of X.Org X11's libXi runtime library handled signed numbers. A malicious X11 server could possibly use this flaw to execute arbitrary code with the privileges of the user running an X11 client.
