Detail

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS Ubuntu 8.04 LTS Ubuntu 8.10 Ubuntu 9.04

This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the following package versions:

Ubuntu 6.06 LTS:
libdbus-1-2 0.60-6ubuntu8.4

Ubuntu 8.04 LTS:
libdbus-1-3 1.1.20-1ubuntu3.3

Ubuntu 8.10:
libdbus-1-3 1.2.4-0ubuntu1.1

Ubuntu 9.04:
libdbus-1-3 1.2.12-0ubuntu2.1

After a standard system upgrade you need to reboot your computer to effect the necessary changes.

Details follow:

It was discovered that the D-Bus library did not correctly validate signatures. If a local user sent a specially crafted D-Bus key, they could spoof a valid signature and bypass security policies.
