Log Message:
- Merge a number of entangled issues from 2.6 / 2.7 audit:
Iteration over sequences could in some cases fail to check access
to an object obtained from the sequence. Subsequent checks (such
as for attributes access) of such an object would still be
performed, but it should not have been possible to obtain the
object in the first place.
List and dictionary instance methods such as the get method of
dictionary objects were not security aware and could return an
object without checking access to that object. Subsequent checks
(such as for attributes access) of such an object would still be
performed, but it should not have been possible to obtain the
object in the first place.
Use of "import as" in Python scripts could potentially rebind
names in ways that could be used to avoid appropriate security
checks.
A number of newer built-ins were either unavailable in untrusted
code or did not perform adequate security checking.
Unpacking via function calls, variable assignment, exception
variables and other contexts did not perform adequate security
checks, potentially allowing access to objects that should have
been protected.
Class security was not properly intialized for PythonScripts,
potentially allowing access to variables that should be protected.
It turned out that most of the security assertions were in fact
activated as a side effect of other code, but this fix is still
appropriate to ensure that all security declarations are properly
applied.
DTMLMethods with proxy rights could incorrectly transfer those
rights via acquisition when traversing to a parent object.
