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       < 1.3.1                       >= 1.3.1
  2  dev-php/phpxmlrpc          < 1.1.1                       >= 1.1.1
    -------------------------------------------------------------------
     2 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

Description
===========

James Bercegay of GulfTech Security Research discovered that the PEAR
XML-RPC and phpxmlrpc libraries fail to sanatize input sent using the
"POST" method.

Impact
======

A remote attacker could exploit this vulnerability to execute arbitrary
PHP script code 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-1.3.1"

All phpxmlrpc users should upgrade to the latest available version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-php/phpxmlrpc-1.1.1"
