DESCRIPTION
The Zope authors have released a new hotfix that addresses a
vulnerability with ZClasses. A user with through-the-web scripting
capabilities on a Zope site can view and assign class attributes to
ZClasses, possibly allowing them to make inappropriate changes to
ZClass instances.
This hotfix also fixes problems in the ObjectManager,
PropertyManager, and PropertySheet classes related to mutability of
method return values which could be perceived as a security problem.
SOLUTION
It is recommended that all Zope users upgrade this software.

upgrades of RPM packages:
