3. Description:
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.
4. Solution:
Before applying this update, make sure all previously-released errata
