Ubuntu 6.06 LTS : Installer vulnerability (USN-316-1)

Ubuntu Security Notice (C) 2006-2013 Canonical, Inc. / NASL script (C) 2007-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

Iwan Pieterse discovered that, if you select 'Go Back' at the final
message displayed by the alternate or server CD installer
('Installation complete') and then continue with the installation from
the installer's main menu, the root password is left blank rather than
locked. This was due to an error while clearing out the root password
from the installer's memory to avoid possible information leaks.

Installations from the alternate or server CDs when the user selected
'Continue' when the 'Installation complete' message was first
displayed are not affected by this bug. Installations from the desktop
CD are not affected by this bug at all.

When you upgrade your passwd package to the newest version, it will
detect this condition and lock the root password if it was previously
blank. The next point release of Ubuntu 6.06 LTS will include a
corrected installer.

Solution :

Update the affected login, passwd and / or user-setup packages.

Risk factor :

High / CVSS Base Score : 7.2
(CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C)
