+Subject: [PATCH] xkb: proof GetCountedString against request length attacks
+
+GetCountedString did a check for the whole string to be within the
+request buffer but not for the initial 2 bytes that contain the length
+field. A swapped client could send a malformed request to trigger a
+swaps() on those bytes, writing into random memory.

+Subject: [PATCH] xkb: fix some possible memleaks in XkbGetKbdByName
+
+GetComponentByName returns an allocated string, so let's free that if we
+fail somewhere.
