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" References ========== [ 1 ] CAN-2005-2498 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2498 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200508-14.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
