"The remote Redhat Enterprise Linux 4 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2005:108 advisory.

    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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
