---------------------------------------------------------------------

1. Topic:

Updated mount packages fixing a potential security problem are available.

2. Relevant releases/architectures:



Red Hat Linux 7.1 - i386

3. Problem description:

If any swap files were created during installation of Red Hat Linux 7.1 
(they were created during updates if the user requested it), they were 
world-readable, meaning every user could read data in the swap file(s), 
possibly including passwords.

The affected swap files are called /mountpoint/SWAP and 
/mountpoint/SWAP-(numeral)

Also, this release of mount enforces sane permissions on swap space.

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.
