Descriptions

There is a stack-based buffer over-read in calling GLib in the function gxps_images_guess_content_type of gxps-images.c in libgxps through 0.3.0 because it does not reject negative return values from a g_input_stream_read call. A crafted input will lead to a remote denial of service attack.

Hay una sobrelectura de búfer basada en pila en la llamada a GLib en la función gxps_images_guess_content_type de gxps-images.c en libgxps hasta la versión 0.3.0 debido a que no rechaza los valores de retorno de una llamada g_input_stream_read. Se podría realizar un ataque de denegación de servicio remoto con una entrada especialmente manipulada.

GNOME is the default desktop environment of Red Hat Enterprise Linux. Issues addressed include buffer overflow, denial of service, and null pointer vulnerabilities.
