Description

Background

The PEAR XML-RPC and phpxmlrpc libraries are both PHP implementations of the XML-RPC protocol.

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"
