-Subject: [PATCH] dix: Disallow GenericEvent in SendEvent request.
-
-The SendEvent request holds xEvent which is exactly 32 bytes long, no more,
-no less. Both ProcSendEvent and SProcSendEvent verify that the received data
-exactly match the request size. However nothing stops the client from passing
-in event with xEvent::type = GenericEvent and any value of
-xGenericEvent::length.
-
-In the case of ProcSendEvent, the event will be eventually passed to
-WriteEventsToClient which will see that it is Generic event and copy the
-arbitrary length from the receive buffer (and possibly past it) and send it to
-the other client. This allows clients to copy unitialized heap memory out of X
-server or to crash it.
-
-In case of SProcSendEvent, it will attempt to swap the incoming event by
-calling a swapping function from the EventSwapVector array. The swapped event
-is written to target buffer, which in this case is local xEvent variable. The
-xEvent variable is 32 bytes long, but the swapping functions for GenericEvents
-expect that the target buffer has size matching the size of the source
-GenericEvent. This allows clients to cause stack buffer overflows.
