Possible DNS leak in SailfishOS 2.0
asked 2016-01-20 11:53:14 +0300
After upgrading to SailfishOS 2.0 I noticed that the DNS cache is not flushed when chaning networks.
This was noticed In networks which use split-view. For example server.example.com may resolve to 7.7.7.7 when connected to the Internet via mobile network (2G/3G/4G). While on a local WLAN it may resolve to 192.168.7.7.
When changing connection from mobile network to WLAN the public IP address is resolved regardless of what the internal DNS server provides.
