The PEAR XML-RPC and phpxmlrpc libraries allow remote attackers to execute arbitrary PHP script commands.
| Package | dev-php/PEAR-XML_RPC on all architectures |

| Affected versions | < 1.2-r1 |
| Unaffected versions | >= 1.2-r1 |
The PEAR XML-RPC and phpxmlrpc libraries are both PHP implementations of the XML-RPC protocol.
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.
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.
There are no known workarounds at this time.
