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

high Nessus Plugin ID 21069

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.
