Comment 6 for bug 1047318

The issue sounds like it's probably still present in Zope 2.12+. Once we get a patch for the issue I can release new 2.12 and 2.13 releases.

The issue doesn't warrant a hotfix as it's only related to restricted code. Restricted code doesn't actually protect against malicious users. It's only a best-effort attempt against introducing accidental security issues for semi-professional developers.
