SuSE Security Announcement
Package: wvdial <= 1.4
Date: Tue, 14 Dec 1999 22:13:51 GMT
Affected SuSE versions: all including 6.3
Vulnerability Type: possible access to dialup passwords
SuSE default package: no
Other affected systems: all unix systems using wvdial
A security hole was discovered in the package mentioned above.
Please update as soon as possible or disable the service if you are
using this software on your SuSE Linux installation(s).
Other Linux distributions or operating systems might be affected
as well, please contact your vendor for information about this
issue.
Please note, that that we provide this information on an “as-is”
basis only. There is no warranty whatsoever and no liability for
any direct, indirect or incidental damage arising from this
information or the installation of the update package.
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
Please verify these md5 checksums of the updates before
installing: (For SuSE 6.0, please use the 6.1 updates)
