Packages : zope
Vulnerability : several
Type : remote
Debian-specific: no
Fixed version : zope 2.1.6-9

This is an addition to DSA 043-1 which fixes several vulnerabilities in Zope. Something went wrong so it has to be corrected. The previous security release 2.1.6-7 has two severe problems: 1. zope 2.1.6-7 erronously included Hotfix 2000-10-02 (a fix for a vulnerability, which does only affect Zope 2.2.0 and later). The inclusion of this Hotfix completely broke the authentification, which rendered zope 2.1.6-7 practically unusable.

The Hotfix 2000-10-02 is removed in 2.1.6-9.

2. The Hotfix 2000-10-11 in zope 2.1.6-7 was non-functional, leaving the package vulnerable to the possible exploit fixed by this Hotfix:

Hotfix 2000-10-11 "ObjectManager subscripting"

The issue involves the fact that the 'subscript notation' that can be used to access items of ObjectManagers (Folders) did not correctly restrict return values to only actual sub items. This made it possible to access names that should be private from DTML (objects with names beginning with the underscore '_' character). This could allow DTML authors to see private implementation data structures and in certain cases possibly call methods that they shouldn't have access to from DTML.

Hotfix 2000-10-11 is fixed in 2.1.6-9 and fixes this vulnerability.

We recommend that you upgrade your zope package immediately.
