    Ubuntu Security Notice USN-1948-1

    python-httplib2 vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 13.04
    - Ubuntu 12.10
    - Ubuntu 12.04 LTS
    - Ubuntu 10.04 LTS
    
    Summary:
    
    Fraudulent security certificates could allow sensitive information to
    be exposed when accessing the Internet.
    
    Software Description:
    - python-httplib2: comprehensive HTTP client library written for Python
    
    Details:
    
    It was discovered that httplib2 only validated SSL certificates on the
    first request to a connection, and didn't report validation failures on
    subsequent requests. If a remote attacker were able to perform a
    man-in-the-middle attack, this flaw could possibly be exploited in certain
    scenarios to alter or compromise confidential information in applications
    that used the httplib2 library.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 13.04:
      python-httplib2                 0.7.7-1ubuntu0.1
    
    Ubuntu 12.10:
      python-httplib2                 0.7.4-2ubuntu0.1
    
    Ubuntu 12.04 LTS:
      python-httplib2                 0.7.2-1ubuntu2.1
    
    Ubuntu 10.04 LTS:
      python-httplib2                 0.7.2-1ubuntu2~0.10.04.2
    
    In general, a standard system update will make all the necessary changes.
