Synopsis: Moderate: python security, bug fix, and enhancement update

Advisory ID: RHSA-2013:1582-02

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-1582.html

Issue date: 2013-11-21

CVE Names: CVE-2013-4238

=====================================================================

 

1. Summary:

 

Updated python packages that fix one security issue, several bugs, and add

one enhancement are now available for Red Hat Enterprise Linux 6.

 

The Red Hat Security Response Team has rated this update as having moderate

security impact. A Common Vulnerability Scoring System (CVSS) base score,

which gives a detailed severity rating, is available from the CVE link in

the References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64

Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64

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

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

 

5. Bugs fixed (https://bugzilla.redhat.com/):

 

521898 - Fix instances of #!/usr/bin/env python in python-tools
