Updated kdelibs packages that fix a local denial of service issue are now available. This update has been rated as having moderate security impact by the Red Hat Security Response Team.
The kdelibs package provides libraries for the K Desktop Environment. Sebastian Krahmer discovered a flaw in dcopserver, the KDE Desktop Communication Protocol (DCOP) daemon. A local user could use this flaw to stall the DCOP authentication process, affecting any local desktop users and causing a reduction in their desktop functionality. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0396 to this issue. Users of KDE should upgrade to these erratum packages, which contain backported patches to correct these issues.
