    <p>
    MoinMoin contains a bug in the code handling administrative group ACLs.
    A user created with the same name as an administrative group gains the
    privileges of the administrative group.
    </p>
  </description>
  <impact type="normal">
    <p>
    If an administrative group called AdminGroup existed an attacker could
    create a user called AdminGroup and gain the privileges of the group
    AdminGroup. This could lead to unauthorized users gaining
    administrative access.
    </p>
  </impact>
  <workaround>
    <p>
    For every administrative group with special privileges create a user
    with the same name as the group.
    </p>
  </workaround>
  <resolution>
    <p>
    All users should upgrade to the latest available version of MoinMoin,
    as follows:
    </p>
    <code>
    # emerge sync
    
    # emerge -pv "&gt;=www-apps/moinmoin-1.2.2"
    # emerge "&gt;=www-apps/moinmoin-1.2.2"</code>
  </resolution>
