CVE request: Invalid pointer dereference in the GNOME librest library

[Florian Weimer <fweimer () redhat com>]

The OAuth implementation in librest, a helper library for RESTful
services part of the GNOME project, incorrectly truncates the pointer
returned by the rest_proxy_call_get_url function call, leading to an
application crash, or worse.
