The following errata for CentOS-2 have been built and uploaded the the centos mirror:

RHSA-2004:412-01 Updated kdelibs and kdebase packages correct security issues

Files available: arts-2.2.2-13.i386.rpm kdelibs-2.2.2-13.i386.rpm kdelibs-devel-2.2.2-13.i386.rpm kdelibs-sound-2.2.2-13.i386.rpm kdelibs-sound-devel-2.2.2-13.i386.rpm

At the moment, kdebase has not been released for 2.1AS (only ES & WS). It seems like it should be so I will try and figure out what is going on.

More details are available from the RedHat web site at https://rhn.redhat.com/errata/rh21as-errata.html

The easy way to make sure you are up to date with all the latest patches is to run: # yum update
