1. Problem Description
If someone uses the wvdial.lxdialog script to configure a ppp dialup,
the config file /var/lib/wvdial/.config is created readable for everyone.
This config file usually contains the login and password for the dialup.
However, the directory where the config file is placed is only accessable
to those in the "dialout" group.
The default wvdial config file of SuSE, which is /etc/wvdial.conf, hasn't
got this problem.
2. Impact
Local users in the "dialout" group might gain access to dialup login
information when the wvdial.lxdialog script is used.
3. Solution
Update the package from our FTP server, or run the command below:
chmod 600 /var/lib/wvdial/.config
