|
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>

|
<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>
