RHSA-2006:0582 - Security Advisory

Topic

Updated kdebase packages that resolve several bugs are now available.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

Description

The kdebase packages provide the core applications for KDE, the K Desktop
Environment. These core packages include the file manager Konqueror.

Ilja van Sprundel discovered a lock file handling flaw in kcheckpass. If
the directory /var/lock is writable by a user who is allowed to run
kcheckpass, that user could gain root privileges. In Red Hat Enterprise
Linux, the /var/lock directory is not writable by users and therefore this
flaw could only have been exploited if the permissions on that directory
have been badly configured. A patch to block this issue has been included
in this update. (CVE-2005-2494)

The following bugs have also been addressed:

• kstart --tosystray does not send the window to the system tray in Kicker
• When the customer enters or selects URLs in Firefox's address field, the

desktop freezes for a couple of seconds

• fish kioslave is broken on 64-bit systems

All users of kdebase should upgrade to these updated packages, which
contain patches to resolve these issues.
