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 References ========== [ 1 ] CAN-2005-0089 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0089 [ 2 ] Python PSF-2005-001 http://www.python.org/security/PSF-2005-001/ Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200502-09.xml 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.
