+Subject: [PATCH 3/3] smtp: avoid risk of buffer overflow in strtol
+
+If the incoming len 5, but the buffer does not have a termination
+after 5 bytes, the strtol() call may keep reading through the line
+buffer until is exceeds its boundary. Fix by ensuring that we are
+using a bounded read with a temporary buffer on the stack.
