Never the less there could be a regression if one of those combinations causes an issue when ran where it formerly just was denied on arg parse. Think a script that since Bionic fails (due to this bug) but once enabled will "work" and DUE TO THAT might then trigger actions that are an issue. Never the less, since currently in Bionic this just fails, I'd assume the this is a rather theoretical risk - and being a regression to former releases we should fix it to make LTS->LTS upgraders suffer less. [Other Info] * n/a Hey, netcat shows a usage error if i try to use the "-s" option: Example in Bionic: $ netcat -s 127.0.0.1 127.0.0.1 22 < /dev/null usage: nc [-46CDdFhklNnrStUuvZz] [-I length] [-i interval] [-M ttl] [-m minttl] [-O length] [-P proxy_username] [-p source_port] [-q seconds] [-s source] [-T keyword] [-V rtable] [-W recvlimit] [-w timeout] [-X proxy_protocol] [-x proxy_address[:port]] [destination] [port] Example in Xenial: netcat -s 127.0.0.1 127.0.0.1 22 < /dev/null SSH-2.0-OpenSSH_7.2p2 Ubuntu-4ubuntu2.4 Manpage shows that the option is still availible and should work.
