Posted to LWN.net: "A potential security issue exists in versions of Zope up to and
including 2.2.4. This 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
privileges to update the raw data of a File or Image object via DTML
though they did not have editing privileges on the objects themselves.
This update replaces the previous Zope update noted in MDKSA-2000:083."
