New Zope packages are available

New Zope packages are available which fix a security flaw with ZClass.

This package includes a "hotfix" product which addresses a security
problem with ZClasses, as descripbed in the Hotfix_2001-05-01 README.txt
file: "The issue is related to ZClasses in that any user can visit a
ZClass declaration and change the ZClass permission mappings for methods
and other objects defined within the ZClass, possibly allowing for
unauthorized access within the Zope instance."

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.
