Description


Alexander Mader has reported a security issue in Debian apt-setup, which can be exploited by malicious, local users to gain knowledge of sensitive information.

The security issue is caused due to the file "apt.conf" being created by "apt-setup" with world readable permission during installation. This makes it possible to gain knowledge of its content, which may contain sensitive information such as the proxy password.

The security issue has been reported in Debian 3.1, "apt" version 0.5.28.1. Other versions may also be affected.


Solution:
Grant only trusted users access to affected systems.
