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

A security issue affects these releases of Ubuntu and its derivatives:

– Ubuntu 13.10
– Ubuntu 12.10
– Ubuntu 12.04 LTS

Summary:

Python could be made to crash or run programs if it received specially
crafted network traffic.

Software Description:
– python2.7: An interactive high-level object-oriented language
– python3.3: An interactive high-level object-oriented language
– python3.2: An interactive high-level object-oriented language

use this issue to cause Python to crash, resulting in denial of service, or
possibly execute arbitrary code.
