Cross reference:
______________________________________________________________________________


1. Problem Description

The OSSP mm library (libmm) allows a local Apache user to gain
privileges via temporary files, possibly via a symbolic link.


2. Vulnerable Supported Versions

System Package

3. Solution

The proper solution is to install the latest packages. Many
customers find it easier to use the Caldera System Updater, called
cupdate (or kcupdate under the KDE environment), to update these
packages rather than downloading and installing them by hand.
