Ubuntu 5.10 : Ubuntu 5.10 installer vulnerability (USN-262-1)

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


Synopsis :

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

Description :

Karl Oie 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.

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 base-config, login and / or passwd packages.

Risk factor :

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