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

high Nessus Plugin ID 27892

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.
