Vulnerability Assessment Details
Ubuntu 5.10 installer vulnerability
Detailed Explanation for this Vulnerability Assessment
These remote packages are missing security patches :
Karl Řie 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 rights 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.
Upgrade to :
- base-config-2.67ubuntu20 (Ubuntu 5.10)
- login-4.0.3-37ubuntu8 (Ubuntu 5.10)
- passwd-4.0.3-37ubuntu8 (Ubuntu 5.10)
