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"
