Detail
A security issue affects the following Ubuntu releases: Ubuntu 5.10 (Breezy Badger) The following packages are affected: base-config passwd The problem can be corrected by upgrading the affected package to version 2.67ubuntu20 (base-config) and 1:4.0.3-37ubuntu8 (passwd). In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Karl Øie discovered that the Ubuntu 5.10 installer failed to clean passwords in the installer log files. Since these files were world-readable, any local user could see the password of the first user account, which has full sudo privileges by default. The updated packages remove the passwords and additionally make the log files readable only by root. This does not affect the Ubuntu 4.10, 5.04, or the upcoming 6.04 installer. However, if you upgraded from Ubuntu 5.10 to the current development version of Ubuntu 6.04 ('Dapper Drake'), please ensure that you upgrade the passwd package to version 1:4.0.13-7ubuntu2 to fix the installer log files. |

23868 | Ubuntu Installer Log File Cleartext Password Disclosure 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. |
