including an automatically generated SSL certificate, used by the quasselcore

daemon.

Software Description:

- quassel: KDE/Qt-based IRC client

Details:

Felix Geyer discovered that the quassel-core post installation script created

data and logging directories which were readable by all users. The post

installation script also generated a certificate, in the data directory, which

was readable by all users.
