GLSA-200502-09 : Python: Arbitrary code execution through SimpleXMLRPCServer
High Nessus Plugin ID 16446
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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.
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.
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.
SolutionAll Python users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose dev-lang/python
