Synopsis
========
TikiWiki and eGroupWare both include PHP XML-RPC code vulnerable to
arbitrary command execution.
Background
==========
TikiWiki is a full featured Free Software Wiki, CMS and Groupware
written in PHP. eGroupWare is a web-based collaboration software suite.
Both TikiWiki and eGroupWare include a PHP library to handle XML-RPC
requests.
Affected packages

Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/tikiwiki < 1.8.5-r2 >= 1.8.5-r2
2 www-apps/egroupware < 1.0.0.009 >= 1.0.0.009
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.

Description
===========
The XML-RPC library shipped in TikiWiki and eGroupWare improperly
handles XML-RPC requests and responses with malformed nested tags.
Impact
======
A remote attacker could exploit this vulnerability to inject arbitrary
PHP script code into eval() statements by sending a specially crafted
XML document to TikiWiki or eGroupWare.
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-1.8.5-r2"
All eGroupWare users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/egroupware-1.0.0.009"
