Description

Updated kdebase packages that fix one security issue are now available for Red Hat Enterprise Linux 4 and 5.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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/'.
