Bug Description

With a strongswan server sending a DNS server to the client, a client running strongswan-nm 5.6.2-1ubuntu2.4 receives random DNS servers. This could lead to a data leak issue, if one of these random DNS servers actually _is_ a DNS server and processes the query (or even a security issue if ths server sends malicious answers).

This was fixed upstream after 5.6.2:
https://git.strongswan.org/?p=strongswan.git;a=commit;h=ee8c25516a97a2c880a8033e1663628b6b05646a

Applying this patch solved the issue.
