Packages       : zope
Vulnerability  : several
Type           : remote
Debian-specific: no
Fixed version  : zope 2.1.6-7

This advisory covers several vulnerabilities in Zope that have been
addressed.

 1. Hotfix 08_09_2000 "Zope security alert and hotfix product"

    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.

 2. Hotfix 2000-10-02 "ZPublisher security update"

    It is sometimes possible to access, through an URL only, objects
    protected by a role which the user has in some context, but not in
    the context of the accessed object.

 3. 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.

 4. Hotfix 2001-02-23 "Class attribute access"

    The issue is related to ZClasses in that a user with through-the-web
    scripting capabilities on a Zope site can view and assign class
    attributes to ZClasses, possibly allowing them to make inappropriate
    changes to ZClass instances.

    A second part fixes problems in the ObjectManager, PropertyManager,
    and PropertySheet classes related to mutability of method return
    values which could be perceived as a security problem.

We recommend you upgrade your zope package immediately.
