Description Mark J. Cox 2005-03-17 12:46:10 UTC

+++ This bug was initially created as a clone of Bug #150090 +++

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 by stalling the DCOP authentication process.

Although it is not possible to by pass the authentication process this way, it
can cause a significant reduction in desktop functionality for the affected users.
