Red Hat, Inc. Security Advisory
Synopsis: Zope update
Advisory ID: RHSA-2000:052-04
Issue date: 2000-08-11
Updated on: 2000-08-18
Product: Red Hat Powertools
Keywords: Zope
Cross references: N/A
---------------------------------------------------------------------
1. Topic:
Vulnerabilities exist with all Zope-2.0 releases. This advisory
supercedes the advisory issued on 2000-08-11. Please use the packages
listed in this advisory instead of the packages refered to previously.
2. Relevant releases/architectures:
Red Hat Powertools 6.1 - noarch
Red Hat Powertools 6.2 - noarch
3. Problem description:
The issue involves the fact that the getRoles method of user objects
contained in the default UserFolder implementation returns a mutable
Python type. Because the mutable object is still associated with the
persistent User object, 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.
Further investigation revealed that it was possible to access the
mutable attribute directly to perform the same exploit.
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:
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_17_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):
