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
Fraudulent security certificates could allow sensitive information to
be exposed when accessing the Internet.
- python-httplib2: comprehensive HTTP client library written for Python
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.
The problem can be corrected by updating your system to the following
Ubuntu 12.04 LTS:
Ubuntu 10.04 LTS:
In general, a standard system update will make all the necessary changes.
To make sure your system is not vulnerable go on to Linux terminal and type " locate python-httplib2" then navigate into the file with command cd in my case was " cd /usr/share/sbin/doc/python-httplib2" Read the copyright documents ... with "less copyright" command and then ...
Upgrade it by running "sudo apt-get install python-httplib2 "
