MoinMoin 1.7.x before 1.7.3 and 1.8.x before 1.8.3 checks parent ACLs in
certain inappropriate circumstances during processing of hierarchical ACLs,
which allows remote attackers to bypass intended access restrictions by
requesting an item, a different vulnerability than CVE-2008-6603.

Hierarchical ACLs were introduced in 1.6.0, so dapper and hardy don't appear to be vulnerable.
