Synopsis
========

Several vulnerabilities have been reported in MoinMoin Wiki Engine.

Background
==========

MoinMoin is an advanced, easy to use and extensible Wiki Engine.

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

    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  www-apps/moinmoin       < 1.6.1                          >= 1.6.1

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

Multiple vulnerabilities have been discovered:

* A vulnerability exists in the file wikimacro.py because the
  _macro_Getval function does not properly enforce ACLs
  (CVE-2008-1099).

* A directory traversal vulnerability exists in the userform action
  (CVE-2008-0782).

* A Cross-Site Scripting vulnerability exists in the login action
  (CVE-2008-0780).

* Multiple Cross-Site Scripting vulnerabilities exist in the file
  action/AttachFile.py when using the message, pagename, and target
  filenames (CVE-2008-0781).

* Multiple Cross-Site Scripting vulnerabilities exist in
  formatter/text_gedit.py (aka the gui editor formatter) which can be
  exploited via a page name or destination page name, which trigger an
  injection in the file PageEditor.py (CVE-2008-1098).

Impact
======

These vulnerabilities can be exploited to allow remote attackers to
inject arbitrary web script or HTML, overwrite arbitrary files, or read
protected pages.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All MoinMoin users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-apps/moinmoin-1.6.1"
