Description Andrej Nemec 2017-03-03 14:52:17 UTC 
When saned receives a SANE_NET_CONTROL_OPTION with value_type == SANE_TYPE_STRING and value_size larger than the actual length of the requested string, the response packet from the server contains a string object as long as value_size in the request. The bytes following the actual string appear to contain memory contents of the server.
