+ <title>Python: Arbitrary code execution through SimpleXMLRPCServer</title>

+ <description>
+ <p>
+ 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.
+ </p>
+ </description>
+ <impact type="high">
+ <p>
+ 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.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ 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.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All Python users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose dev-lang/python</code>
+ </resolution>
