    Synopsis
    ========

    MoinMoin contains a bug allowing anonymous users to bypass ACLs (Access
    Control Lists) and carry out operations that should be limited to
    authorized users.

    Background
    ==========

    MoinMoin is a Python clone of WikiWiki, based on PikiPiki.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-www/moinmoin <= 1.2.2 >= 1.2.3

    Description
    ===========

    MoinMoin contains two unspecified bugs, one allowing anonymous users
    elevated access when not using ACLs, and the other in the ACL handling
    in the PageEditor.

    Impact
    ======

    Restrictions on anonymous users were not properly enforced. This could
    lead to unauthorized users gaining administrative access to functions
    such as "revert" and "delete". Sites are vulnerable whether or not they
    are using ACLs.

    Workaround
    ==========

    There is no known workaround.

    Resolution
    ==========

    All users should upgrade to the latest available version of MoinMoin,
    as follows:

        # emerge sync

        # emerge -pv ">=net-ww/moinmoin-1.2.3"
        # emerge ">=net-ww/moinmoin-1.2.3"
