kdelibs -- local DCOP denial of service vulnerability

A KDE Security Advisory reports:

Sebastian Krahmer of the SUSE LINUX Security Team
reported a local denial of service vulnerability in KDE’s
Desktop Communication Protocol (DCOP) daemon better known
as dcopserver.
A local user can lock up the dcopserver of arbitrary
other users on the same machine. This can cause a
significant reduction in desktop functionality for the
affected users including, but not limited to, the
inability to browse the internet and the inability to
start new applications.
