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"
