Hotfix_2000-12-15a

  This is a "hotfix" product. Hotfix products can be installed to 
  incorporate modifications to Zope at runtime without requiring 
  an immediate installation upgrade. Hotfix products are installed 
  just as you would install any other Zope product.

  This hotfix addresses an important security issue that affects all 
  released Zope versions up to and including Zope 2.2.4 final.

  The issue involves the computation of local roles.  In some situations
  the computation was not climbing the correct hierarchy of folders,
  sometimes granting local roles inappropriately.  This could allow
  users with privileges in one folder to gain the same privileges in
  another folder.

  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 if the site is accessible by untrusted users 
  who may have localized privileges.
