Red Hat: RHSA-2010:0348-01 Important: kdebase Privilege Escalation

red hat
Calendar Grey April 14, 2010
Dist Redhat Esm H88
Red Hat Security Bulletin outlines important kdebase patch with significant repercussions for RHEL versions 4 and 5. Upgrade suggested.
Updated kdebase packages that fix one security issue are now available for Red Hat Enterprise Linux 4 and 5

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at

Summary

The K Desktop Environment (KDE) is a graphical desktop environment for the X Window System. The kdebase packages include core applications for KDE.
A privilege escalation flaw was found in the KDE Display Manager (KDM). A local user with console access could trigger a race condition, possibly resulting in the permissions of an arbitrary file being set to world writable, allowing privilege escalation. (CVE-2010-0436)
Red Hat would like to thank Sebastian Krahmer of the SuSE Security Team for responsibly reporting this issue.
Users of KDE should upgrade to these updated packages, which contain a backported patch to correct this issue. The system should be rebooted for this update to take effect. After the reboot, administrators should manually remove all leftover user-owned dmctl-* directories in "/var/run/xdmctl/".
