User updates for Python packages address security issues and bugs in Red Hat Enterprise Linux, ensuring enhancement.
Updated python packages that fix one security issue, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 6

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258

Summary

Python is an interpreted, interactive, object-oriented programming language.
A flaw was found in the way the Python SSL module handled X.509 certificate fields that contain a NULL byte. An attacker could potentially exploit this flaw to conduct man-in-the-middle attacks to spoof SSL servers. Note that to exploit this issue, an attacker would need to obtain a carefully crafted certificate signed by an authority that the client trusts. (CVE-2013-4238)
These updated python packages include numerous bug fixes and one enhancement. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.5 Technical Notes, linked to in the References, for information on the most significant of these changes.
All users of python are advised to upgrade to these updated packages, which fix these issues and add this enhancement.
