Synopsis
========

Multiple vulnerabilities have been discovered in TikiWiki, possibly
resulting in the remote execution of arbitrary code.

Background
==========

TikiWiki is an open source content management system written in PHP.

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

    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  www-apps/tikiwiki      < 1.9.8.3                       >= 1.9.8.3

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

Stefan Esser reported that a previous vulnerability (CVE-2007-5423,
GLSA 200710-21) was not properly fixed in TikiWiki 1.9.8.1
(CVE-2007-5682). The TikiWiki development team also added several
checks to avoid file inclusion.

Impact
======

A remote attacker could exploit these vulnerabilities to inject
arbitrary code with the privileges of the user running the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All TikiWiki users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-apps/tikiwiki-1.9.8.3"
