Synopsis
=======
Python-based XML-RPC servers may be vulnerable to remote execution of
arbitrary code.

Background
=========
Python is an interpreted, interactive, object-oriented, cross-platform
programming language.

Affected packages
================
    -------------------------------------------------------------------
     Package          /  Vulnerable  /                      Unaffected
    -------------------------------------------------------------------
  1  dev-lang/python      <= 2.3.4                         >= 2.3.4-r1
                                                          *>= 2.3.3-r2
                                                          *>= 2.2.3-r6

Description
==========
Graham Dumpleton discovered that XML-RPC servers making use of the
SimpleXMLRPCServer library that use the register_instance() method to
register an object without a _dispatch() method are vulnerable to a
flaw allowing to read or modify globals of the associated module.

Impact
=====
A remote attacker may be able to exploit the flaw in such XML-RPC
servers to execute arbitrary code on the server host with the rights of
the XML-RPC server.

Workaround
=========
Python users that don't make use of any SimpleXMLRPCServer-based
XML-RPC servers, or making use of servers using only the
register_function() method are not affected.

Resolution
=========
All Python users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose dev-lang/python
