From: "Brian Lloyd" <brian@digicool.com> To: <zope-announce@zope.org>, <zope@zope.org> Subject: [Zope] SECURITY alert and hotfix release Date: Fri, 8 Dec 2000 15:48:52 -0500 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.
