Severity: High Title: Python: Arbitrary code execution through SimpleXMLRPCServer Date: February 08, 2005 Bugs: #80592 ID: 200502-09

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

Availability ============
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:

Concerns? =========
Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
