+Subject: [PATCH 1/3] 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.
