Description

The input path in routed(8) will accept queries from any source and attempt to answer them. However, the output path assumes that the destination address for the response is on a directly connected network. Impact : Upon receipt of a query from a source which is not on a directly connected network, routed(8) will trigger an assertion and terminate. The affected system
