KNOPPIX CD Default Configuration May Let Local Users Grab Root Privileges
SecurityTracker Alert ID: 1007142
CVE Reference: GENERIC-MAP-NOMATCH (Links to External Site)
Date: Jul 9 2003
Impact: Modification of system information, Modification of user information, Root access via local system
Exploit Included: Yes
Description: A vulnerability was reported in the default configuration of the KNOPPIX CD. A local user can obtain root privileges.
It is reported that the "knx-hdinstall" default configuration creates unsafe temporary files in the '/tmp/.qt/' directory: 'qt_plugins_3.0rc', and 'qt_plugins_3.0rc.lock'. A local user can create a symbolic link (symlink) from a critical file on the system to one of these temporary files. Then, when a target user logs in, the symlinked file will be overwritten with the privileges of the target user, potentially including the root user.
Impact: A local user can cause a target user to overwrite a file on the system with the privileges of the target user. This can be exploited by a local user to potentially obtain root privileges.
Solution: No solution was available at the time of this entry.
Vendor URL: www.knoppix.org/ (Links to External Site)
Cause: Access control error, State error
Reported By: Hugo "Vazquez" "Carames" <overclocking_a_la_abuela@hotmail.com>
Message History: None.

I installed with an older build of 3.2 and have no such directory.
The solution is to reboot your pc... all user created files in /tmp will be deleted, even on a hard drive install.
This is (IMHO) a very LOW risk (but one I want to be aware of regardless). Here's why I would consider this low risk: you need local (hands on) access to install or use knoppix from a cd anyways! When you have physical access, and boot from a knoppix cd, root access is readily available. After you do a hard drive install and reboot, the system security is only going to be as good as your setup guarding against know vulnerabilities.
My two cents, and worth every penny.
