In
+encode_ie() the bound check did not consider that each byte from
+the IE causes two bytes to be written into buffer. That could
+lead to a kernel oops, but does not allow code injection. This is
+now fixed.
+
+Due to the type of this problem it does not trigger another
+urgent security bugfix release. v0.9.3 is at the door anyway.
