    March 03, 2014
    
    python2.6, python2.7, python3.2, python3.3 vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 13.10
    - Ubuntu 12.10
    - Ubuntu 12.04 LTS
    - Ubuntu 10.04 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
    - python2.6: An interactive high-level object-oriented language
    
    Details:
    
    Ryan Smith-Roberts discovered that Python incorrectly handled buffer sizes
    when using the socket.recvfrom_into() function. An attacker could possibly
    use this issue to cause Python to crash, resulting in denial of service, or
    possibly execute arbitrary code.
