Update to stunnel 5.22
The stunnel package is currently on 5.01 this is considerably old and this should be updated. Updating this fixes a number of severe security issues.
There are other problems with the APKBUILD too.
* checkpath: owner `root:stunnel' not found * checkpath: owner `stunnel:stunnel' not found
It doesn’t appear to create the correct user stunnel and group stunnel. The process should be run by this user and the configurations in /etc/stunnel should be owned by this user/group.
Updating this APKBUILD would silence this warning.

stunnel is required by those who experience some sort of DPI (deep packet inspection) which involves throttling/blocking of OpenVPN connections.
