1. Topic:

Updated kdelibs packages fixing a security problem, some memory leaks and 
some minor bugs are available.

2. Relevant releases/architectures:



Red Hat Linux 7.1 - i386

3. Problem description:

kdesu created a world-readable temporary file to exchange authentication 
information and delete it shortly after. This can be abused by a local 
user to gain access to the X server and can result in a compromise of the 
account kdesu accesses.

This update also fixes memory leaks in Konqueror (khtml) and KDebug, as 
well as some minor bugs.

kdelibs 2.2alpha1 includes those fixes, as well; if you're using the 
experimental package from rawhide or ftp.kde.org, you don't need to 
downgrade to the errata package for security reasons.

4. Solution:

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains
the
desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed  (http://bugzilla.Red Hat.com/bugzilla for more info):

tampered with, examine only the md5sum with the following command:
    rpm --checksig --nogpg
