Products.Zope_Hotfix_20111024 1.0

Overview

This hotfix addresses a serious vulnerability in the Zope2 application server. Affected versions of Zope2 include:

• 2.12.x <= 2.12.20

• 2.13.x <= 2.13.6

Older releases (2.11.x, 2.10.x, etc.) are not vulnerable.

The Zope2 security response team recommends that all users of these releases upgrade to an unaffected release (2.12.21 or 2.13.11) as soon as they become available.

Until that upgrade is feasible, deploying this hotfix also mitigates the vulnerability.

Installing the Hotfix: Via ‘easy_install’

If the Python which runs your Zope instance has ‘setuptools’ installed (or is a ‘virtualenv’), you can install the hotfix directly from PyPI:

$ /prefix/bin/easy_install Products.Zope_Hotfix_20111024

and then restart the Zope instance, e.g.:

$ /path/to/instance/bin/zopectl restart

Installing the Hotfix: Via ‘zc.buildout’

If your Zope instance is managed via ‘zc.buildout’, you can install the hotfix directly from PyPI. Edit the ‘buildout.cfg’ file, adding “Products.Zope_Hotfix_20111024” to the “eggs” section of the instance. E.g.:

[instance]
recipe = plone.recipe.zope2instance
#...
eggs =
  ${buildout:eggs}
  Products.Zope_Hotfix_20111024

Next, re-run the buildout:

$ /path/to/buildout/bin/buildout

and then restart the Zope instance, e.g.:

$ /path/to/buildout/bin/instance restart

Installing the Hotfix: Manual Installation

You may also install this hotfix by unpacking the tarball and adding a ‘products’ key to the ‘etc/zope.conf’ of your instance. E.g.:

products /path/to/Products.Zope_Hotfix_20111024/Products

Verifying the Installation

After restarting the Zope instance, check the ‘Control_Panel/Products’ folder in the Zope Management Interface, e.g.:

http://localhost:8080/Control_Panel/Products/manage_main

You should see the ‘Zope_Hotfix_20111024’ product folder there.
