<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 &quot;&gt;=www-apps/moinmoin-1.2.2&quot;
# emerge &quot;&gt;=www-apps/moinmoin-1.2.2&quot;</code>
</resolution>
