=========================================================== Ubuntu Security Notice USN-262-1 March 12, 2006 Ubuntu 5.10 installer vulnerability CVE-2006-1183 =========================================================== 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.
