+	  <p>Olivier Fourdan from Red Hat has discovered a protocol handling
+	    issue in the way the X server code base handles the XkbSetGeometry
+	    request.</p>
+	  <p>The issue stems from the server trusting the client to send valid
+	    string lengths in the request data. A malicious client with string
+	    lengths exceeding the request length can cause the server to copy
+	    adjacent memory data into the XKB structs. This data is then
+	    available to the client via the XkbGetGeometry request. The
+	    data length is at least up to 64k, it is possible to obtain
+	    more data by chaining strings, each string length is then
+	    determined by whatever happens to be in that 16-bit region of
+	    memory.</p>
+	  <p>A similarly crafted request can likely cause the X server
+	    to crash.</p>
