Background ========== The PEAR XML-RPC and phpxmlrpc libraries are both PHP implementations of the XML-RPC protocol. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-php/PEAR-XML_RPC < 1.4.0 >= 1.4.0 2 dev-php/phpxmlrpc < 1.2-r1 >= 1.2-r1 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Stefan Esser of the Hardened-PHP Project discovered that the PEAR XML-RPC and phpxmlrpc libraries were improperly handling XMLRPC 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 web applications making use of these libraries. Workaround ========== There are no known workarounds at this time. Resolution ========== All PEAR-XML_RPC users should upgrade to the latest available version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-php/PEAR-XML_RPC-1.4.0" All phpxmlrpc users should upgrade to the latest available version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-php/phpxmlrpc-1.2-r1" References ========== [ 1 ] CAN-2005-2498 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2498 [ 2 ] Hardened-PHP 14/2005 Advisory http://www.hardened-php.net/advisory_142005.66.html [ 3 ] Hardened-PHP 15/2005 Advisory http://www.hardened-php.net/advisory_152005.67.html Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200508-13.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.
