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"
