Sebastian Krahmer has reported a vulnerability in KDE, which can be exploited by malicious, local users to cause a DoS (Denial of Service).

The vulnerability is caused due to an error in the authentication process in the DCOP (Desktop Communication Protocol) daemon dcopserver. This can be exploited to lock the dcopserver for arbitrary local users. Successful exploitation may result in decreased desktop functionality for the affected user.

The vulnerability has been reported in versions prior to 3.4.

Solution: Upgrade to KDE 3.4 or apply patch.
