Description

The Ubunto installer contains a flaw that may lead to an unauthorized password exposure. The installer log files fail to sanitize passwords used during the installation. The installer log files are world-readable, thus any local user can see the password of the first user account, which has full sudo privileges by default, thus leading to a loss of confidentiality.
