3. Problem description:

The util-linux package contains a large variety of low-level system
utilities that are necessary for a Linux system to function. 

A flaw was discovered in the way that the mount and umount utilities
used the setuid and setgid functions, which could lead to privileges being
dropped improperly.  A local user could use this flaw to run mount helper
applications such as, mount.nfs, with additional privileges (CVE-2007-5191).

Users are advised to update to these erratum packages which contain a
backported patch to correct this issue.

4. Solution:

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

This update is available via Red Hat Network.  Details on how to use 
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/FAQ_58_10188

5. Bug IDs fixed (http://bugzilla.redhat.com/):

320041 - CVE-2007-5191 util-linux (u)mount doesn't drop privileges properly when calling helpers
