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

Ubuntu Security Notice (C) 2006-2016 Canonical, Inc. / NASL script (C) 2007-2016 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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

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)
