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): N/A 6. RPMs required: Red Hat Powertools 6.2: noarch: ftp://updates.redhat.com/powertools/6.2/noarch/Zope-Hotfix-DTML-08_17_2000-1.noarch.rpm sources: ftp://updates.redhat.com/powertools/6.2/SRPMS/Zope-Hotfix-DTML-08_17_2000-1.src.rpm 7. Verification: MD5 sum Package Name -------------------------------------------------------------------------- 89f08b0f1e53da3c1945132ce1736516 6.2/SRPMS/Zope-Hotfix-DTML-08_17_2000-1.src.rpm 0e6d83f627f9daee652001f07fd4d668 6.2/noarch/Zope-Hotfix-DTML-08_17_2000-1.noarch.rpm These packages are GPG signed by Red Hat, Inc. for security. Our key is available at: http://www.redhat.com/corp/contact.html You can verify each package with the following command: rpm --checksig <filename> If you only wish to verify that each package has not been corrupted or tampered with, examine only the md5sum with the following command: rpm --checksig --nogpg <filename> 8.
