Peter Hutterer reports:

+
Olivier Fourdan from Red Hat has discovered a protocol handling + issue in the way the X server code base handles the XkbSetGeometry + request.
+
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.
+
A similarly crafted request can likely cause the X server + to crash.
