[Zope] ANNOUNCE: Zope security alert and hotfix release

2000-12-18 Thread Brian Lloyd

Hi all -

  

  Peter Kelly has brought another potential security issue to
  our attention that is important enough to make a Hotfix
  available for those who allow untrusted users to edit DTML
  on their sites.

  The issue involves incorrect protection of a data updating method
  on Image and File objects. Because the method was not correctly
  protected, it was possible for users with DTML editing priveleges
  to update the raw data of a File or Image object via DTML though
  they did not have editing priveleges on the objects themselves.

  We 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 have DTML
  editing privileges.

  http://www.zope.org/Products/Zope/Hotfix_2000-12-18/Hotfix_2000-12-18.tgz

  The hotfix will work for all versions of Zope 2.1.x and higher. A
  Zope 2.2.5 release later this week will contain the fix for this
  issue (as well as all hot fixes to date) and you will be able to
  uninstall the hot fix after upgrading.

[Zope] ANNOUNCE: Zope security alert and hotfix release

2000-12-15 Thread Brian Lloyd

Hi all -

  A security issue has recently come to our attention (thanks to
  Erik Enge for identifying this) that affects Zope versions up to
  and including Zope 2.2.4.

  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.

  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.

  Note that we will be making a Zope 2.2.5 release early next week
  that includes the fix for this issue as well as the issue addressed
  by the recent 12/08 hotfix.
