Low: util-linux security and bug fix update

An updated util-linux package that corrects a security issue and fixes
several bugs is now available.

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

The util-linux package contains a collection of basic system utilities.

A flaw was found in the way the login process handled logins which did not
require authentication. Certain processes which conduct their own
authentication could allow a remote user to bypass intended access policies
which would normally be enforced by the login process. (CVE-2006-7108)

This update also fixes the following bugs:

* The partx, addpart and delpart commands were not documented.

* The "umount -l" command did not work on hung NFS mounts with cached data.

* The mount command did not mount NFS V3 share where sec=none was specified.

* The mount command did not read filesystem LABEL from unpartitioned disks.

* The mount command did not recognize labels on VFAT filesystems.

* The fdisk command did not support 4096 sector size for the "-b" option.

* The mount man page did not list option "mand" or information about
/etc/mtab limitations.

All users of util-linux should upgrade to these updated packages, which
contain backported patches to correct these issues.
