Python is an interpreted, interactive, object-oriented programming language.
An object traversal bug was found in the Python SimpleXMLRPCServer. This bug could allow a remote untrusted user to do unrestricted object traversal and allow them to access or change function internals using the im_ and func_ attributes. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0089 to this issue.
Users of Python are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
