Synopsis
=======
The PEAR XML-RPC and phpxmlrpc libraries allow remote attackers to
execute arbitrary PHP script commands.
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"
