Synopsis:          Zope update
Advisory ID:       RHSA-2000:052-02
Issue date:        2000-08-11

1. Topic:

Vulnerabilities exist with all Zope-2.0 releases.

2. Relevant releases/architectures:

Red Hat Powertools 6.1 - noarch
Red Hat Powertools 6.2 - noarch

3. Problem description:

This HotFix corrects issues in the getRoles method of user objects
contained in the default UserFolder implementation. Users with the ability
to edit DTML could arrange to give themselves extra roles for the duration
of a single request by mutating the roles list as a part of the request
processing.

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:=20

ftp://ftp.redhat.com/pub/redhat/powertools/6.2/

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-DTML-08_09_2000-1.noarch.rpm

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

5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
