RHSA-2005:109 - Security Advisory

Topic

Updated Python packages that fix a security issue are now available for Red
Hat Enterprise Linux 3.

Description

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 this issue.
