[Zope] SECURITY alert and hotfix release

[Brian Lloyd]

Hi all,

  Aleksander Salwa has brought a security issue to our attention
  that affects all Zope versions up to and including Zope 2.2.4.
  We have released a Hotfix product to address the issue that can
  be downloaded from zope.org. (Thanks to Aleksander for finding
  this and to Shane Hathaway for his quick response in resolving
  it!)

  The issue involves security registration of "legacy" names for
  certain object constructors such as the constructors for DTML
  Method objects. Security was not being applied correctly for the
  legacy names, making it possible to call those constructors without
  the permissions that should have been required. This issue could allow
  anonymous users with enough internal knowledge of Zope to instantiate
  new DTML Method instances through the Web.

  The hotfix for this issue is available on the zope.org web site:

    o
http://www.zope.org/Products/Zope/Hotfix_2000-12-08/Hotfix_2000-12-08.tgz

  We *highly* recommend that any Zope site running versions of
  Zope up to and including 2.2.4  have this hotfix product installed
  to mitigate the issue.

  The hotfix will work for all versions of Zope 2.2.0 and higher. A
  future version of Zope will contain the fix for this
  issue, and you will be able to uninstall the hot fix after upgrading.
