GLSA-200502-09 : Python: Arbitrary code execution through SimpleXMLRPCServer

This script is Copyright (C) 2005-2015 Tenable Network Security, Inc.

Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200502-09
(Python: Arbitrary code execution through SimpleXMLRPCServer)

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.

Solution :

All Python users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose dev-lang/python

Risk factor :

High / CVSS Base Score : 7.5
