Ubuntu Security Notice USN-401-1
4th January, 2007
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 6.10
- Ubuntu 6.06 LTS
- Ubuntu 5.10
Kimmo Hämäläinen discovered that local users could delete other users'
D-Bus match rules. Applications would stop receiving D-Bus messages,
resulting in a local denial of service, and potential data loss for
applications that depended on D-Bus for storing information.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 6.10:
- dbus 0.93-0ubuntu3.1
- Ubuntu 6.06 LTS:
- dbus 0.60-6ubuntu8.1
- Ubuntu 5.10:
- dbus 0.36.2-0ubuntu7.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to reboot your computer to
effect the necessary changes.
