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
-------------------------------------------------------------------

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.

arbitrary code with the privileges of the user running the application.
Workaround
