kdelibs security update

Updated kdelibs packages that correct an integer overflow flaw are now
available.

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

The kdelibs package provides libraries for the K Desktop Environment (KDE).
Qt is a GUI software toolkit for the X Window System.

An integer overflow flaw was found in the way Qt handled pixmap images.
The KDE khtml library uses Qt in such a way that untrusted parameters could
be passed to Qt, triggering the overflow. An attacker could for example
create a malicious web page that when viewed by a victim in the Konqueror
browser would cause Konqueror to crash or possibly execute arbitrary code
with the privileges of the victim. (CVE-2006-4811)

Users of KDE should upgrade to these updated packages, which contain a
backported patch to correct this issue.

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