1. Topic:

Remote vulnerabilities exist with all Zope-2.0 releases.

2. Relevant releases/architectures:

3. Problem description:

This hotfix corrects issues with an inadequately protected method in one of the 
base classes in the DocumentTemplate package that could allow the contents of 
DTMLDocuments or DTMLMethods to be changed remotely or through DTML code without 
forcing proper user authorization.

4. Solution:

Users of Red Hat Powertools 6.1 who have not upgraded Zope to the version of 
Zope released in Red Hat Powertools 6.2 (2.1.2-5) need to do so prior to 
installing this Zope update. The Zope packages from 6.2 are located at:

After you have upgraded to Zope-2.1.2-5 install the Zope-Hotfix package. To 
install the update, use this command:

rpm -Uvh Zope-Hotfix-06_16_2000-1.noarch.rpm

Once the Zope-Hotfix package is installed, restart Zope.
